Building an npk production line requires a compound fertilizer granulator. There are many compound fertilizer processing and granulation equipment. Some companies do not know how to choose a suitable compound fertilizer granulator. What is the compound fertilizer granulation equipment introduced today? There are three main types of compound fertilizer granulator: drum granulator, disc granulator and double-roller granulator. What is the difference between these compound fertilizer granulators? What are the advantages and disadvantages of each method?

The disc granulator mainly uses the rolling of the disc surface and the granulation of the granules themselves, and is used together with the upper mixer to achieve a high spheroidization rate. The investment cost of granulator equipment is low, and the production capacity is strong, but the dust of open-air granulation is relatively large.

The barrel of the drum granulator equipment is lined with a special rubber plate or an acid-resistant stainless steel lining to realize automatic scar removal and tumor removal, eliminating the traditional scraper device. A drum granulator is a forming machine that shapes materials into specific shapes.

The main working method is granule wet granulation. With a certain amount of water or steam, the basic fertilizer can fully react after being humidified in the tank. Under certain liquid phase conditions, with the help of the rotating motion of the cylinder, the extrusion force between the material particles condenses into balls. The investment cost of chemical fertilizer equipment is high, the production capacity is strong, and the dust of drum granulation is relatively small.

The double-roll granulator adopts non-drying normal temperature process to produce, one-time molding. The equipment has low investment, quick effect and good economic benefit. The whole set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., and the product granulation rate is high. Various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.) can be produced.

For friends who are preparing to start production of organic fertilizers, there are many things that need to be done, such as project establishment, production plan, process selection, equipment purchase, plant construction, and there may be bidding matters. Since 2020, due to the rising price of raw materials, which has a greater impact on the price of equipment, many friends are very concerned about how much it costs to put into production an organic fertilizer equipment?

First of all, in the case of equipment purchase alone, the price of a set of organic fertilizer production equipment may range from tens of thousands to several million. There are many factors that affect the price of organic fertilizer equipment. Production capacity, raw materials, and equipment selection must also consider the rise and fall of equipment raw materials. Today, I will use two different customer production cases last year to explain the price of the equipment in detail and see which situation is suitable for you.

1. Simple configuration of organic fertilizer equipment to produce fermented organic fertilizer

If the organic fertilizer is produced on a small scale, commercial sales are not required, only the pre-fermentation process is required, and the subsequent deep processing is not required. At present, there are three forms of organic fertilizer fermentation equipment:

1. Choose an organic fertilizer fermentation tank.

Fermentation tank processing organic fertilizer is suitable for the conditions of strict environmental protection requirements and high fermentation aging requirements. At present, the use of fermentation tanks to process organic fertilizer can produce raw materials within 48 hours. The fermentation tank can be equipped with a deodorization system to completely solve the environmental pollution problem. It is not affected by the external temperature and environmental terrain, and can be produced at any time.

2. Adopt small trough type compost turning machine.

The trough-type manure compost turning machine runs stably, and can be changed by one turning-and-turning machine. It can handle multiple trough materials with large output and uniform turning and polishing. Most organic fertilizer processing plants are used. The small 2-meter trough-type turning and polishing machine is only priced at 5 thousand dollars.

3. Use self-propelled compost turning machine.

The self-propelled manure composting machine is divided into wheel type and crawler type. It is characterized by large processing capacity and free movement. It is suitable for organic fertilizer dumping operations in a wide area, and is suitable for organic fertilizer processing plants that do not want to carry out a large amount of civil engineering. The price of the type turning machine is about 10,000 dollars.

2. Simple configuration of equipment for producing powdered organic fertilizer

The production of powdered organic fertilizer is finely pulverized after the fermentation of organic fertilizer. The required equipment: fermentation dumper, forklift silo, semi-wet material shredder, drum screening machine, automatic packaging is called powder organic fertilizer. This low-end configuration of powder organic fertilizer production equipment can be realized at a price of about 30,000-90,000 dollars.

3. Equipment for producing granular organic fertilizer

The production process of granular organic fertilizer is relatively complete and complicated at present, and it is also based on continuous fermentation process and powder organic fertilizer processing. Therefore, the required equipment is relatively more, including fermentation machine, forklift silo, semi-wet material crusher, horizontal mixer, organic fertilizer granulator machine, dryer, cooler, drum screening machine, fertilizer film coating machine and automatic packaging machine. When the process has special needs, dynamic ingredients are also needed. The price of a small complete set of equipment is about $100,000-$140,000.

For professional fertilizer processing enterprises, the production capacity requirements are relatively large. For an organic fertilizer production line with an annual output of 50,000 tons, the equipment price is between $90,000 and $150,000. Such a price range is a reasonable range that takes into account the different needs of different customers.

The above is the approximate price of organic fertilizer production equipment. Since 2021, the price of metals has soared, pushing up the price of equipment, and the specific situation should be based on real-time quotation.

However, in the actual process design, because the production capacity requirements of each project, the ground processing site, and the configuration of the entire set of organic fertilizer production equipment are not fixed, there are often many different situations, so the specific price depends on the situation. FPC will generally provide customers with process design, equipment processing and installation, and production training for free according to the actual situation of the customer. Let customers achieve mass production without any worries.

High-temperature composting technology generally uses aerobic tank fermentation to make compost, and uses a tank turning machine to ferment and turn the pile. For large yields, a roulette turning machine can be used to ferment and turn. It can also be decomposed by strip-chop fermentation, using a crawler turning machine or walking type turning machine. It can ensure enough high temperature to kill the parasites and roundworm eggs, and kill the vegetative cells of pathogenic bacteria, and kill weed seeds, and consume the energy such as carbohydrates in the materials as much as possible, so as not to be applied to the soil in the future. After the middle, it causes undesirable phenomena such as burning roots and seedlings. At the same time, the high temperature has the conditions to consume as much as possible the crude fiber in the feces and the hydrocarbons in the straw. If the hydrocarbons in the crude fiber and straw are not removed, after applying this fertilizer to the soil in the future, one will burn the roots, and the other is because the carbon-nitrogen ratio of this fertilizer is too high, which will cause a large number of microorganisms to heat up. At the same time, it will compete for the nitrogen source in the soil to balance the carbon-nitrogen ratio, which will result in an unfavorable situation of competing with plants for fertilizer, resulting in slender roots and seedlings. At the same time, the use of a trough-type compost turner for fermentation and aerobic fermentation can ensure rapid fermentation and keep farmers in the middle of the two crops. In a short period of time, the straw decomposing process is fully completed.

Fermentation of organic fertilizers is to use chain plate type compost turning machines that can process livestock and poultry manure and strip-type crawler turning and throwing machines to ferment and decompose. The second is to use aerobic fecal fermentation tank for fermentation, which has a short operating period and high processing efficiency. The heat generated by the fermentation in the fermenter rises, which can preheat the upper layer of feces and facilitate the flow of air and the supply of oxygen. The fermentation tank is divided into multiple layers, and each layer can be fermented. After the manure is put into the fermentation tank, the manure is transferred and turned over by the turning of the flap. The operation is simple, the energy consumption is low, and the floor space is small and the maintenance is convenient. The third is that the flap is provided with vent holes, and the flap is directly left with fine slits. The bottom of each layer of fermentation chamber is arranged with air pipes, which improves the aeration capacity, reduces the energy consumption of the fan, and makes the air distribution more uniform. However, it is difficult for the staff to understand the processing conditions of high-temperature fermentation of livestock and poultry manure from the outside. The livestock and poultry manure after high temperature treatment can be slowly dropped to the top of the transfer truck or on the receiving conveyor to complete the automation of the device, and the waste gas generated during fermentation is processed by a dedicated waste gas processor. The exhaust gas treated by the processor meets the emission requirements. The fecal material that has been fermented and decomposed needs to be thoroughly decomposed in the aging field. The aging field is also called the secondary fermentation plant. The secondary fermentation generally takes 5-7 days, and the secondary fermentation time can also be determined according to the production volume. The maximum time should not exceed 20 days. The white mycelium inside the fermentation product and the aroma of distiller’s grains will be produced at the same time. The secondary fermentation field can also be used as a raw material storage field. The pellets made of raw materials that are not fermented and decomposed are easy to swell after bagging.

Granular and powder organic fertilizer production line

Next, the fermented raw materials are crushed, and a special crusher can be used to crush to the granulation requirements, generally 0.5-0.08mm (24-50 mesh). At this time, the crushed raw materials are put into a horizontal mixer for mixing, and humic acid can be added or nitrogen, phosphorus, potassium, reinforcing powder, and organic matter can be added to meet the requirements of the formula and meet the national standards. The agitated raw materials are crushed by a chain pulverizer and then sent to an organic fertilizer granulator for granulation. During granulation, the angle of the granulator and the pressure of the water supply can be adjusted according to the required particle size to form balls, and the ball formation rate can reach 95%.

At this time, the manufactured particles are sent to the dryer for drying. The length and diameter of the dryer are determined according to the output. The retention time of particles in the dryer is generally about 30-40 minutes. The particles are dispersed in the dryer through the lifting device to fully absorb heat. The heat is generated by the hot blast stove and sent to the dryer through the induced draft fan to dry the particles, suck away the moisture, and enter the dust removal room. After the gas entering the dust removal room is processed, it meets the air emission requirements, and then is discharged into the atmosphere. This meets the requirements of air environmental protection. At the same time, the dried semi-finished product is sent to the cooler for cooling. The feed temperature is generally 60-80 degrees, and the temperature of the cooled material is generally about 30 degrees. Then the cooled semi-finished product is sent to the sieving machine for screening For classification, the particle size of the finished product is between 2.5-5.5, and the finished particles after sieving are sent to the coating machine.

Send the large over-standard particles and small particles into the chain-type powder mill after stirring to be crushed and re-granulated. Color to achieve customer satisfaction, and the coating agent contains certain nutrients to achieve slow-release purpose). The particles sent into the finished product warehouse are weighed and packaged by an automatic weighing and packaging machine. When weighing, they are bagged according to their own set weight. After sealing, the finished organic fertilizer can be sent to the finished product warehouse or shipped out of the factory.

The organic fertilizer granulator is the main mechanical facility for granulating the fermented organic fertilizer. There are also a wide variety of organic fertilizer granulators. The well-known ones are extrusion granulators, disc granulators, drum granulators, roller extrusion granulators, flat film granulators, and so on. So how do we distinguish them in our work?

Rotary Drum Fertilizer Granulating Machine

The drum granulator is suitable for organic and inorganic materials. In addition, the equipment is easy to operate, flexible in work, and convenient to maintain.

The disc granulator relies on water spray to granulate, because the granulation rate can reach more than 93%. The pelletizing tray is equipped with three discharge ports, which is convenient for intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

The particles of the extrusion granulator can be directly bagged. The extrusion granulator is also suitable for metallurgical material particles, refractory material particles, and mineral powder particles. There is no need to add drying equipment when designing an organic fertilizer production line. The investment of the extrusion granulator is small, and the effect is quick, with an annual output of 10,000 to 100,000 tons.

New Developed Goat Manure Compost Pellet Machine

The roller extrusion granulator is a granulating equipment. It is produced by the non-drying process, one-time molding, and the output is 1-1.5 tons/hour and 1.5-3 tons/hour. The organic fertilizer granulator has low investment, quick effect and good economic benefits.

Although there are many types of organic fertilizer granulators, each has its own unique function, and the output will increase if combined with supporting production. After everyone understands these differences, there should be some changes in the use of organic fertilizer granulators.

The construction of the organic fertilizer production line is related to many aspects. Manufacturers often encounter many problems when building organic fertilizer production lines. I don’t know how to choose the machines needed in each link and how to produce organic fertilizer with high quality and high price. Let me explain to you how to build an organic fertilizer production line correctly.

Generally speaking, the production of organic fertilizer can be divided into four major steps: fermentation-crushing-granulation-drying-packaging. These necessary steps also have more extended procedures, such as stirring, cooling, screening, and coating.

How the customer chooses an organic fertilizer production line often depends on the raw materials needed to make organic fertilizer. For example, in the crushing process, different crushers are selected according to the water content of the raw materials. Usually, we should use a semi-wet material pulverizer to crush the raw materials with higher water content. If it is dry material, such as dry cow dung and sheep dung, we can use a vertical grinder to crush it. In the granulation process, we recommend different types of granulators according to the fiber size of the raw materials. We usually use discs or drum granulators for finer fiber raw materials, such as chicken manure. The coarser fiber materials use flat film extrusion granulator, such as cow dung, straw and so on. In the drying process, if the budget is sufficient, we often recommend that customers install a cooler after the drying process, which is mainly to prevent the agglomeration caused by overheating of the particles. In the later stage of granulation, there are also optional processes such as coating and polishing. These are all procedures for “beauty” for the finished product, making the granules more beautiful, neat and attractive.

In a whole set of organic fertilizer production line, granulation is a key process in the whole production process. The productivity of the organic fertilizer granulator, the strength and shape of the granules produced directly affect the quality of the product.

Rotary Drum Fertilizer Granulating Machine

Among the many organic fertilizer production enterprises, the most used organic fertilizer granulation equipment includes drum granulator, extrusion granulation machine and disk granulator machine. Among the three granulation methods, the disc granulator is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is more ideal. The disc granulator is mainly composed of granulation disc, spray system, transmission device, bracket and so on.

Pig Manure Granulation Machine

During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator, and the rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, under the action of its own gravity and inertial force, it breaks away from the disc and slides down along the arc-shaped trajectory to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling materials to agglomerate them into granules, thus completing the entire granulation process. According to the principle applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveying equipment below.

Double Roller Powder Granulator

As an old model, the disc granulator has experienced the test of various materials, but any equipment has advantages and disadvantages. With the diversification of raw materials, organic fertilizer equipment manufacturers are constantly developing new granulation equipment. In the production of ordinary organic fertilizers, there is a new type fertilizer stirring tooth granulator, which has high production efficiency and good product quality. In terms of organic-inorganic compound fertilizer, there is also a new type compound fertilizer granulator, which is improved on the basis of the stirring tooth granulator, but it has solved the problem of material sticking to the wall. It’s also very beautiful. The diversification of raw materials has promoted the diversification of organic fertilizer granulation equipment. Only by purchasing equipment suitable for your own materials can the whole set of organic fertilizer equipment be effective.

It is well known that the organic fertilizer granulator is a special equipment for the production of organic fertilizer granules, and there are many problems or failures in the organic fertilizer granulation opportunity. As an organic fertilizer granulator manufacturer, we will face the user of the organic fertilizer granulator during the three guarantees service period. Summarize the problems or failures encountered, and draw the following points of maintenance and use for readers and users.

First, do a good job of heat preservation. Due to the climate and environment, the drive parts of the organic fertilizer granulator will start slowly or fail to start due to freezing. This requires that the workplace of the organic fertilizer granulator or the organic fertilizer granulator itself must have certain insulation measures. The raw materials used in the work of the organic fertilizer granulator must also be antifreeze treatment. The moisture content of the organic fertilizer raw materials is low, and the antifreeze treatment is also critical for the winter use of the organic fertilizer pellet machine.

Second, use special lubricants. Low temperature and skillful use frequency will cause the lubricating oil to encounter condensation and freeze retention, which will affect the lubricating oil supply of the organic fertilizer granulator. It can be maintained by adding lubricating oil to the affected organic fertilizer granulator in time. Better use effect.

Third, reasonable maintenance. Every time the work is completed, the organic fertilizer granulator must be inspected and maintained. The main focus is on the transmission part, the lubrication part and the cleaning of residual materials. Maintenance and repair are the basis for the use of the organic fertilizer granulator in winter. And replace the faulty parts of the organic fertilizer granulator in time to avoid the operation of the organic fertilizer granulator and reduce the production and use costs caused by the machine failure. Reasonable maintenance also needs to be completed regularly to ensure the maintenance and attention of each component. Make the organic fertilizer granulator show better results.

Pan Granulator Machine

As long as you pay attention to the main points of the use and maintenance of the organic fertilizer granulator and take corresponding measures, the quality-guaranteed organic fertilizer granulator will better serve our production and production of organic fertilizer particles. The benefit of granulator, drum granulator, disc granulator, organic fertilizer granulator, fertilizer granulation equipment is maximized.

What aspects should be paid attention to in FPC large, medium and small organic fertilizer equipment investment? Analyze the price factors of various types of organic fertilizer equipment. In summary, there are seven basic factors that affect the investment price and production of organic fertilizer.

• Determine the size of the organic fertilizer equipment. For example, how many tons are produced per year, or how many tons are produced per hour, can the price be determined.
• Determining the shape of the particles is what kind of granulator to choose. It is powdery, columnar, oblate or standard round. Commonly used equipment for granulating organic fertilizers are: disc granulator, drum granulator, wet granulator, roller extrusion granulator, flat die granulator, ring film granulator. The selection of the granulator should be decided according to the local fertilizer sales market. The particle shape is different, the process of the organic fertilizer equipment is also different, and the price of the organic fertilizer equipment is also different.

Pig Manure Granulation Machine

• Determine the configuration level of organic fertilizer equipment. The level of configuration is different, the price of organic fertilizer equipment is different, the amount of labor used is different, and the stable and high yield of organic fertilizer equipment is also different: generally higher configuration, automatic batching device, automatic packing device, automatic quantitative feeding device, water Screen dust removal and so on.
• Determine the type of fertilizer produced. It is compound fertilizer equipment or organic fertilizer equipment. For the same output, organic fertilizer equipment generally takes into account the high water content and the strains are not resistant to high temperatures. The model is generally larger than the compound fertilizer model. There are four types of general organic fertilizers, pure organic fertilizer, organic-inorganic compound fertilizer, biological organic fertilizer, compound microbial fertilizer, and the organic fertilizer equipment is different for different varieties.
• Selection of fermentation turning machine. The general fermentation forms include stack fermentation, shallow fermentation, deep tank fermentation, tower fermentation, and rotary drum fermentation. The fermentation methods are different, and the fermentation organic fertilizer equipment is also different. Generally, aerobic fermentation with a shallow trough turning machine is used (the advantages of a shallow trough turning machine: conform to the principle of aerobic fermentation, not easy to form anaerobic, fully complete fermentation, and fast fermentation).

Wheel type Compost Turner for Large Scale Composting

• Determine the level of environmental protection requirements. Places with low environmental protection requirements generally choose to reduce dust and reduce the investment in organic fertilizer equipment. Places with high environmental protection requirements generally choose heavy dust removal and ink dust removal, which can meet the air emission quality standards.
• The price of each model varies according to the required degree of automation. The price of equipment with high degree of automation is correspondingly high, but it can save manpower.

The production process of the organic fertilizer production line refers to the process of processing waste resources containing organic matter into commercial organic fertilizers through corresponding equipment through harmless treatment. The detailed process has the following steps:

• Preparation of raw materials before fermentation: all raw materials used for fermentation are processed to a particle size below 1-60mm through crushing equipment, which is convenient for improving the contact surface of the materials during fermentation.
• Fermentation of raw materials: the ratio of raw materials, adjust the water content and the ratio of various raw materials, the adjustment of the raw material ratio should meet the normal range of carbon to nitrogen ratio of about 30:1, and the addition of other auxiliary materials should be combined with local market demand or soil testing The result of adjustment is that the fermented organic fertilizer product has better adaptability.

• Raw material crushing: The fermented raw materials have been fully decomposed, and can be finely crushed using a semi-moisturematerial shredder. The crushed particle size is suitable for the requirements of raw material granulation.
• Raw material mixing: The raw materials after fermentation are combined with market demand. If you need to add other auxiliary materials, you need to use a mixer for full mixing, or some raw materials need to add auxiliary granulation materials to improve the success rate of raw materials granulation.

• Drying and cooling: The granulated material still contains about 30% moisture. Use a dryer to dry its moisture below 15%, and then use a cooler to quickly cool down and shape, improve the strength of the pellet, and facilitate transportation and storage.
• Particle screening: The cooled particles are classified by a drum screening machine. The oversized or undersized particles are crushed and re-granulated, and the qualified products are screened out and flowed into the next process.
• Finished product coating: Coating qualified products to increase the brightness and roundness of the particles.
