In the organic fertilizer production industry, there are many types of equipment that can make organic fertilizer, and there are different supporting equipment according to different materials. We use poultry manure as raw material to analyze the two different organic fertilizer production of drum granulator and disc granulator.

The advantages and disadvantages of each granulator.

Disc granulation process characteristics:

The operation is intuitive, and the operation of the equipment can be grasped at any time. If an abnormality is found, the size of the particles can be adjusted in time. It is determined by the inclination and rotation speed of the disc, and the inclination and rotation speed of the disc can be adjusted. The control range of the particle size is wide, the adaptability is strong, and the ball formation rate is very high, which can reach 70% to 90%. The livestock manure organic fertilizer disc granulation process has short production process, simple structure, low investment and easy operation, which is more suitable for small and medium-sized enterprises.

Characteristics of drum granulation process:

Steam is introduced into the material layer in the drum to increase the temperature of the granulated material, dissolve the salt of the granulated material, and achieve a high liquid phase volume under low moisture content to meet the liquid phase volume required for material granulation. At the same time, the amount of evaporated water in the drying process is reduced. The inner wall of the drum is lined with a number of soft rubber plates or polypropylene plates, and there are vent holes at the corresponding positions on the cylinder. When the inner lining turns from the bottom to the upper with the cylinder at the same time, the inner lining sags due to its own weight, thereby causing adhesion The material on the inner lining falls due to gravity to achieve the function of automatically cleaning the conglomerate. During the operation, the operator can observe the ball formation of the material at any time, and take corresponding measures in time as needed to ensure the normal operation of the system.

There are quality pan granulator and rotary drum granulator in FPC. Welcome to our website to buy granulation machines.

FPC disc granulator has the following advantages: high spheroidization rate, high roundness and strength of particles, intuitive operation, convenient maintenance, etc.

The working principle of the disc granulator: The powdered fertilizer is evenly moistened by the atomized water in the double-shaft mixer to form a spherical core with a uniform particle size, and then sent to the spherical disc for granulation. The moisture content of raw materials should be controlled at 12~14%. Most of the water should be added in the double-shaft mixer, and only a small amount of supplemental water should be added to the ball pan, and the supplemental water amount should be controlled at about 0~3%. Dry powder granulation is directly added to the ball-forming disc, and an appropriate amount of water is sprayed. After the raw material ball core enters the ball-forming disc, it moves along a parabola under the action of centrifugal force, friction and gravity in the disc. Due to the cohesiveness and plasticity of the material, the cores adhere to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the high speed of the disc edge and the water content are constant, the material balls of different particle sizes will leave the disc edge and roll down at different detachment angles due to different gravity. The material ball continuously pushes the water out of the surface during the continuous rolling process. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the material ball has a certain strength, and then with the rotation of the inclined plate body The edge of the disc is discharged out of the disc.

Stirring-teeth granulator:

The new type of organic fertilizer granulator is also called a spiral stirring tooth structure due to its internal structure , Granulation, spheroidization, densification and other processes, so as to achieve the purpose of granulation. The particle shape is spherical, the particle size is generally between 0.3-3 mm, and the granulation rate is 90%. The size of the particle diameter can be appropriately adjusted by the mixing amount of the material and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the larger the particle size. Small, and vice versa. Application range: This machine is especially suitable for the granulation of light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the quality of the pellets. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, etc.

It is dedicated to the granulation of municipal solid waste organic fermented fertilizer such as manure, compost, green manure, sea manure, cake manure, grass charcoal, soil and miscellaneous manure, three wastes, microorganisms, etc. The particles are spherulites. The granulation rate of the machine is as high as 80-90%, and it is suitable for a variety of different formulas. The compressive strength of organic fertilizer is higher than that of discs and drums. The rate of large balls is less than 15%. The uniformity of particle size can be customized according to user requirements. It is adjusted through the stepless speed regulation function of this machine. This machine is suitable for the direct granulation of organic fertilizer after fermentation, which saves the drying process and greatly reduces the manufacturing cost.

What is detailed NPK compound fertilizer production line?

The process flow of NPK compound fertilizer production line is as follows:

• Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, ordinary calcium), potassium chloride (potassium sulfate) and other raw materials are equipped in a certain proportion (according to Market demand and soil testing results in various places).
• Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the entire fertilizer particles.
• Raw material granulation: send the uniformly stirred raw materials to the granulator for granulation (rotary drum granulator or extrusion granulator can be used).
• Granule drying: The granules made by the granulator are sent to the dryer, and the moisture contained in the granules is dried to increase the strength of the granules and facilitate storage.
• Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging storage and transportation.
• Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
• Finished film: Coating qualified products to increase the brightness and roundness of the particles.
• Finished product packaging: Pack the film-coated particles, that is, the finished product, and store it in a ventilated place.

Belt conveyor is a common equipment used for continuous conveying of goods. There are two types of belt conveyors, fixed and mobile, which are mainly used for loading, unloading, handling and conveying goods or materials. It is the most basic equipment in the manufacturing process of organic fertilizer, which can connect various machines and transport materials. Belt conveyor deviation is one of the common faults in the operation of belt conveyor. There are many reasons for this, including structural design, installation and commissioning. When solving the deviation problem, it needs to be handled flexibly according to the situation.

Harm of belt conveyor deviation

The deviation of belt conveyor means that the conveyor belt deviates from the normal center position to one side of the transmission drum. In this case, if not corrected in time, the edge of the conveyor belt and the frame will rub against each other, and the conveyor belt will wear or even tear over time. In case of serious, the production of nitrogen, phosphorus and potassium fertilizer will stop working, affecting the production efficiency.

Causes of belt conveyor deviation

The reason for belt conveyor deviation is that the forces on both sides of the conveyor belt are unbalanced. If the tension at both ends of the belt is in a balanced state, it is not easy for the newly installed and debugged belt conveyor or the worn old belt conveyor to deviate.

There is a reversing roller at the head and tail of the belt conveyor, which is installed at the head and tail respectively. The head roller is installed and positioned, the central axis is perpendicular to the frame, and the tail roller is equipped with a lead screw as a tensioning device. The perpendicularity between the idler and the frame can be adjusted by adjusting the nut position on the lead screw until the final belt conveyor operates normally.

Pay attention to the time of fertilization

Organic fertilizer is slow to use, so it should be applied as early as possible. It is usually used as the base fertilizer before sowing or sowing, and fermentation will be better before use. The latter is less effective than the basic fertilizer.

Fertilizer has a quick effect, and should be used as base fertilizer one week in advance. Fertilizer should be applied before the critical period of crops or during the peak period of nutrient absorption to meet their needs.

Biological fertilizer plays an important role in inhibiting bacteria in soil. Therefore, under the premise of bacteria having reproductive growth time, it should be applied early, which can be applied with organic fertilizer for soil or during implantation or implantation before application.

Second, pay attention to the application method

The main function of organic fertilizer is to improve the soil and provide nutrients, which is usually used as the basic fertilizer in the soil. Therefore, the organic fertilizer and soil should be mixed evenly with the deep plough to achieve the purpose of improving the soil. It can also be used in combination with microbial agents for acid-base reproduction, which will improve the soil environment, balance nutrition and increase the structure of soil aggregates. To make fertilizer met the requirements, it is necessary to select a realiable organic fertilizer machine manufacturer.

In the basic fertilizer, because the nutrients in the organic fertilizer are mainly nitrogen, it can reduce the nitrogen fertilizer in the organic fertilizer, the base fertilizer can use 30%, the rear fertilizer can use 70%. Phosphate fertilizer and potassium fertilizer can be paid off as base fertilizer at one time. The fluidity of phosphate fertilizer is poor, and the recovery effect is poor in the later stage. Therefore, the phosphate fertilizer should be applied to the soil as the base fertilizer.

The best way to apply the fertilizer is to use the full solution quick acting fertilizer, such as the source Bank of P and K, which can be absorbed quickly after the decomposition of vegetables, which has little influence on the soil. Biomass fertilizer can be concentrated in planting sites or based on organic fertilizer because of its small quantity. The latter can be used to produce long bacteria by using the same kind of biological fertilizer to improve the removal ability and disease prevention effect of phosphorus and potassium solution.

Finally, pay attention to the dose

Different crops have different growth stages. The amount of fertilizer is different, so the amount of fertilizer should be controlled, and the fertilizer should be applied according to the different needs of plants, and the content of nutrient elements in soil should be considered comprehensively

Application of organic fertilizer throughout the year can renew or improve soil organic matter, improve soil physical and chemical properties, and significantly improve soil quality. With the rapid development of modern agriculture, fertilizer is essential. Fertilizer granulation plant sxfp will share with you the key points of rational use of organic fertilizer.

The advantage of organic fertilizer is that it contains a variety of nutrients, including a lot of micronutrients, and contains a lot of organic matter, vitamins and other active substances. The rational use of organic fertilizer should pay attention to the following points:

Pan Granulation Compound Fertilizer Production Line

Long term application of organic fertilizer can renew or increase soil organic matter, improve soil physical and chemical properties, and significantly improve soil quality. However, the disadvantage is that the nutrient content is low, and the nutrient form is mainly organic. It needs to decompose soil microorganisms gradually and transform them into the form of plant absorption and utilization. Because of the low nutrient supply intensity, it is difficult to meet the requirements of rapid growth cycle of high-yield crops. To use good fertilizer, the manufacture should choose a quality fertilizer granulation machine supplier, which will be the first and foremost thing.

In the process of organic fertilizer production, we should not only consider the characteristics of various organic fertilizers, but also consider the application of appropriate fertilizers. That’s what SXFP ALWAYS DO.

In terms of livestock manure, the amount of this organic fertilizer is very large. With the rapid development of livestock and poultry industry, livestock and poultry industry develops rapidly. If animal manure is not treated and applied scientifically, it will not only cause the loss of vegetables, fruit trees, tobacco, tea, potatoes and other economic crops, but also worsen the agricultural environment.

New Type Organic Fertilizer Production Line

Therefore, in the production of cash crops, it is necessary to fully develop and rationally use organic fertilizer. Because the main characteristic of organic fertilizer is that its nutrient content is higher than other organic fertilizers, the carbon nitrogen ratio (C / N) is relatively narrow, usually between 6 and 10.

Therefore, some crushed rice straw was added to form a mixed organic fertilizer, and then other NPK fertilizers were added and granulated by a double roll granulator. In this way, we can clean the environment and ensure the quality and safety of fruit and vegetable products. The application of organic fertilizer can partly replace the supply of nitrogen and phosphorus in crops, thus reducing the application of fertilizer and improving the utilization rate of fertilizer.

In the working process of organic fertilizer granulating machine, it is required that the material has a certain viscosity. Some raw materials are loose after fermentation, and it is not easy to granulation. If it is not easy to granulation, some water or adhesive should be added to increase the viscosity of the material. Organic fertilizer equipment pan granulator and rotary granulator are granulated by pellet method. Water or binder will be added in the process of granulation to ensure the smooth granulation of materials. The new organic fertilizer granulator adopts wet granulation method, and the material after fermentation can be directly granulated, without the operation of other processes.

If the moisture content of the material is too high, you can add some dry materials to neutralize the moisture content. If the water content is too low, it is easy to granulation.

The new type of organic fertilizer granulator is an organic fertilizer granulation equipment which is continuously updated and rebuilt with the development of agriculture, the improvement of technology and the diversity of demands. The new type of wet granulator can realize the larger selection of materials. As long as all kinds of organics after effective fermentation can be granulated through the new type of organic fertilizer granulator, breaking the limitations and obstacles of traditional technology.

Before granulation, there is no need to stop the processing, crushing and boring tasks of raw materials, which can directly realize the batching processing and direct granulation, which not only saves a small amount of power input, but also effectively reduces the cost, and also realizes the greater improvement of task efficiency, which is convenient and fast, and the effect is satisfactory. The new type of organic fertilizer granulator also achieves 100% organic content, realizing the exclusive manufacture of pure organic fertilizer.
