The price of organic fertilizer machines for processing cow dung ranges from tens of thousands to hundreds of thousands of dollars. It is necessary to determine the specific list of cow dung organic fertilizer equipment according to the predetermined annual production volume and production process standards.

Powdery organic fertilizer production line

What equipment is needed to process cow dung organic fertilizer?

Generally speaking, the equipments required for the cow dung powder organic fertilizer production line include fermentation turners, pulverizers, mixers, and screening machines. The cow dung granule organic fertilizer production line needs to add organic fertilizer granulator, organic fertilizer dryer, cooler, coating machine, etc. on the basis of the powder production line.

Windrows for windrow composting working

Fermentation process of cow dung:

1. First, control the moisture of cow dung organic fertilizer raw materials to be about 50% before fermentation. The methods of controlling moisture include solid-liquid separation method and auxiliary material adjustment moisture method.
2. Add organic fertilizer starter or organic fertilizer strain starter according to the process requirements to the raw materials. In order to improve the fermentation speed and fermentation uniformity, mixing equipmentof organic fertilizercan be used for mixing when adjuvant materials are added.
3. Put the raw materials into the trough fermentation tank or the organic fertilizer manure fermentation tankto start fermentation. Fermentation tanks are organic fertilizer fermentation equipment with a high degree of automation. The operation is simple and convenient in the process, and does not require too much effort. The trough fermentation method needs to pay attention to the fermentation temperature at all times. When the temperature of the fermentation pile reaches 70 degrees, the trough-type composting turner should be used for turning in time, usually once every 2 days or so. The purpose is to avoid killing beneficial bacteria when high temperature kills harmful substances. After the fermentation is completed, it can enter the next process of producing powdery organic fertilizer or granular organic fertilizer.

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.

Wheel type Compost Turner for Large Scale Composting

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%.

fertilizer rotary drum granulator

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.

People who are engaged in agriculture and breeding industry know that fertilization with unripe cow manure has low effect and can cause damage to the rhizomes of crops. Fermented cow dung has high fertilizer efficiency.

Cow dung organic fertilizer production line

If cow dung is made into organic fertilizer, the fertilization effect will be even better. Because cow dung contains a lot of nutrients needed for crop growth, processing and utilization can not only reduce the pollution of cow dung to the environment, and solve the problem of manure treatment in farms, it can also be a good profitable project. If a cow produces about 30-40 kg of excrement per day, a cattle farm with 500 cows can build a small organic fertilizer production line. So what are the production processes of cow dung organic fertilizer, let’s briefly introduce it next.

organic fertilizer large fermentation pot

Fermentation: Add organic solid waste such as straw, wood chips, etc. with moisture content of less than 60% to fresh cow manure, and mix it as an auxiliary material with microbial fermentation inoculants to regulate moisture, aeration, and carbon-nitrogen ratio. The water content of cow dung is controlled at about 68%, and it is fully decomposed, sterilized, deodorized, and dewatered through fermentation equipment. The moisture content of the decomposed material is generally in the range of 30-35%.

Ingredients crushing and mixing: Ingredients crushing and mixing use the ingredient bin to pass the composted materials, and other additives and other raw materials in a certain proportion through the material crusher and horizontal mixer for crushing, proportioning and mixing.

Cow Manure Granulation Machine

Granulation: Use an organic fertilizer granulator to make granules of the treated cow dung.

Screening: The granular material output from the granulation forming system has a certain difference in particle size and needs to be screened and classified. It is recommended to be equipped with an automatic material return system to screen out unqualified large and small particles, convey them through a belt elevator, and send them to the granulator to continue granulation after re-pulverization, which helps to improve the continuous operation capacity of the production line.

Drying: Use organic fertilizer drying equipment to further remove moisture from the material and solidify it to reach the standard moisture content of organic fertilizer.

Cooling: The cooler cools the granular material, which helps the granule storage and quality.

fertilizer single bucket packing machine

Packing: The cooled granular materials are transported into the finished product warehouse through the bucket elevator. Granular materials can be quantitatively weighed and packaged through automatic packaging scales.

Advantages of cow manure organic fertilizer: cow manure organic fertilizer will also add a lot of organic matter to your soil. By mixing this compost into the soil, you can increase the moisture retention capacity of the soil. This reduces moisture, because the roots of the plant can use extra moisture and nutrients when needed. Welcome to leave comments.

There are also many types of mixers. For different materials and industries, different types have different performances, and the mixing process will also be very different, as well as the effect on the finished product. Today, I will introduce the working principles of various forms of mixers.

single shaft organic fertilizer mixing machine

Single shaft horizontal mixer

This type of mixer is a batch type discharging, and its feeding and discharging system is carried out in a certain cycle cycle. The material enters the mixing chamber, and the unloading system is turned on to discharge the material after being fully stirred and mixed. The continuous discharging is the simultaneous mixing operation of the material from the feeding port to the discharging port. Therefore, in terms of the mixing quality, the mixing quality of the batch mixer is better than that of the continuous mixer.

In the process of mixing and mixing materials, in order to obtain better mixing and mixing effects and save energy. It is required that the materials cannot be thrown up in series during the mixing and stirring of the materials. Because the movement of the material is affected by the rotating spiral blade, the movement of the material is not simply along the edge.

It moves linearly along the spiral axis, but moves back and forth in space along the spiral axis. The material is affected by the friction between the spiral blades and the friction between the materials.

In the whole mixing and stirring process, when the spiral speed exceeds a certain speed, the material will jump in the direction perpendicular to the axial direction due to excessive centrifugal force. The weakening of the axial thrust will affect the convection of the material, thereby reducing the uniformity of the material mixing.

double shaft mixing machine

Double shaft mixer

Compared with the single-shaft horizontal mixer, the double-shaft organic fertilizer mixer is a continuous discharge. It is suitable for use in mass production. Because the single-shaft horizontal mixer cannot provide enough mixing materials for production due to the limitation of its own volume and the limitation of mixing time, the double-shaft mixer that can continuously discharge the material plays a great role in this case.

Similar to the double-shaft screw conveyor, the two horizontally arranged augers inside the machine are the main working parts of the mixer. The motor transmits power through the auger shaft to drive the auger blades to rotate, and the auger blades are fixed on the auger shaft by a screw rod. , Its angle can be adjusted according to production needs to control its discharging speed and mixing quality. The centering design of the spiral blades of the double auger realizes multi-directional circulation such as axial horizontal stirring and circular movement of the material. The mixing mode includes a variety of mixing processes.

The two counter-rotating auger shafts drive the blades to rotate relative to each other, so that the mixture can realize tangential and axial compound movements. The stirring device enables the components of the mixture to be sheared, kneaded and evenly mixed. The discharged materials are all in the form of granules or powders. They are adhesive materials with good scattering properties and are beneficial to the later granulation.

vertical type mixing machine

Vertical mixer machine

Different from the cylindrical gear reducer used in the horizontal mixer, the reducer of the vertical organic fertilizer mixer adopts a vertical cycloid reducer. The mixing chamber is a low cylindrical structure, and the materials are spread in a thin layer. Therefore, the required power is not very large, and it is more suitable for mixing fertilizer raw materials.

Because the fertilizer raw materials are easy to absorb moisture and have a certain viscosity, they are easy to stick to the wall of the pan during production, forming a dense material bonding layer, resulting in high internal friction of the machine and making the blending mixer bear excessive load. In order to avoid causing the motor overload to affect production, movable protective nets are installed at the feeding ports. On the one hand, it prevents too much material from entering the mixer, on the other hand, it is used as a safety protection measure to prevent accidents during operation.

The inside of the silo can also be lined with plastic plates to reduce material adhesion and friction, and it is not easy to cause corrosion of the disk body, which extends the service life of the whole machine.

The organic fertilizer production line with an annual output of 5,000 tons is a small organic fertilizer production line, and its configuration includes: fermentation turning machine, grinder, granulator, dryer, and screening machine. If necessary, automatic packaging machines, etc. must be prepared. These equipments are generally indispensable.
