The raw materials for compound fertilizer include urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate, monoammonium phosphate, diammonium phosphate, heavy calcium, superphosphate, and other raw materials. These raw materials have the advantages of reasonable granulation, high nutrient content, few by-products, and good physical properties. They play a very important role in balancing fertilization, improving fertilizer utilization efficiency, and promoting high and stable crop yields. What equipment is needed for the production of compound fertilizer besides the roller extrusion granulator?

What other supporting equipment are needed for compound fertilizer granulation besides the roller extrusion granulation machine? The roller squeezing granulator is the main equipment for granulating powder material composite fertilizers. In addition to the roller squeezing granulator, it also requires a fully automatic batching machine, a mixer, a vertical crusher, a drum screening machine, a dryer, a cooling machine, a secondary drum screening machine, and an automatic packaging scale. The equipment is connected by a belt conveyor.

The twin roll squeezing granulator utilizes paired rolling rolls with adjustable gaps between them, which rotate in opposite directions at the same speed. The surface of the rolling mill is regularly arranged with many arc grooves of the same shape and size. According to the different compression ratios of the material object, it is selected to use the groove of one rolling mill to align exactly with the groove of the other rolling mill. The two rolling rolls are in a horizontal parallel state, and the powder like material is continuously and uniformly fed between the two rolling rolls by its own weight and forced feeding from above. When the material enters the biting area, it is gradually bitten by the rolling rolls. With the continuous rotation of the rolling rolls, the space occupied by the material gradually decreases and is gradually compressed, reaching the maximum value of the forming pressure. Then, the pressure gradually decreases, resulting in clumps, Due to the elastic recovery and the weight of the rolled sheet, the arc groove of the rolling roller falls off. Next, it enters the cutting device and is screened into granular products.

The layout of the complete set of compound fertilizer production equipment is compact, scientifically reasonable, and technologically advanced. No discharge of three wastes, stable operation, reliable operation, and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, etc. The product has a high granulation rate and a small footprint. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.).

The chicken manure organic fertilizer production line uses fresh chicken manure as raw material, undergoes a series of processing treatments, and produces high-quality chicken manure organic fertilizer. There are two steps required for processing commodity organic fertilizers: the pre fermentation and treatment part and the deep processing granulation part. The complete production line equipment includes fermentation stacker, forklift silo, crusher, mixer, granulation machine, dryer, cooling machine, screening machine, coating machine, packaging machine, belt conveyor, and other equipment.

Process flow of organic fertilizer granulation production line configuration:

1. The processing of organic fertilizers mainly involves collecting raw materials, then proportioning them according to the required formula, adjusting the moisture and carbon nitrogen ratio of the raw materials, and starting fermentation.

2. Fine crush the fermented raw materials to achieve the required particle size before granulation.

3. Add the crushed raw materials to the corresponding auxiliary materials and stir evenly.

4. Organic fertilizer granulator is used to granulate the mixed raw materials. The granulator includes disc granulator, new wet granulator, polishing machine, drum granulator and other models. Appropriate granulators are selected according to the characteristics of raw materials.

5. The prepared particles are transported to an organic fertilizer dryer, and their original moisture content is dried to below 15% to increase their particle strength.

6. The dried particles are transported to the organic fertilizer cooler and quickly cooled and shaped by natural or forced cold air.

7. There may be some oversized or undersized unqualified particles in the produced particles, which will be screened out using a screening machine. The unqualified particles will be returned to the corresponding process to remake the particles, and the qualified particles will enter the next process.

8. Use a coating machine to evenly spray a layer of coating agent on the periphery of the particles, which can effectively supplement the trace elements of the product and improve its brightness and fullness.

9. Qualified products are transported to a fully automatic packaging scale for weighing, packaging, and warehousing, and all processing processes are completed.

How much is the equipment for the chicken manure organic fertilizer production line

The equipment for a simple chicken manure organic fertilizer production line is within 100000 yuan, and the customer requirements vary. The organic fertilizer production line we configure for each customer also varies. The low configuration of the chicken manure organic fertilizer production line only requires a crusher, mixer, granulator, screening machine, and packaging machine. This is a basic configuration, and equipment is added according to the actual needs and requirements of customers. Therefore, the equipment prices for the entire chicken manure organic fertilizer production line range from tens of thousands to hundreds of thousands.

The main types of inorganic fertilizers produced by npk fertilizer production line are: mineral phosphate fertilizer, mineral potash fertilizer, compound fertilizer, nitrogen fertilizer.

Trace element fertilizer: copper, iron, boron, zinc, manganese, molybdenum and other trace elements and beneficial element fertilizer.

Biological organic fertilizer production line fertilizer: compost, manure, biogas fertilizer, green fertilizer, crop straw, cake fertilizer, humic acid fertilizer, amino acid fertilizer, commercial organic fertilizer, bone meal, agricultural and livestock processing waste, sugar factory waste, etc

In order to ensure that the base fertilizer can adequately supply the nutrition of the whole growth period of vegetables, the method of organic fertilizer mixed with chemical fertilizer is often adopted in the base fertilizer. Usually the required phosphorus fertilizer, potash fertilizer 20%-50%, nitrogen fertilizer 30%-50% mixed into organic fertilizer. The amount of chemical fertilizer should be adjusted according to the quality and quantity of organic fertilizer used. On the one hand, adding bio-bacterial fertilizer to the bottom fertilizer can improve the soil better and improve the utilization rate of nutrient absorption; On the other hand, biologic fertilizer can play a role in preventing root disease and crop damage by bacteriostasis.

Fertilizers should be used in combination with organic fertilizers and large amount of elemental fertilizers with medium and trace elements. The economical and reasonable application of nitrogen fertilizer depends on the soil fertility level and the target yield. In the application method, deep application should be applied to reduce nitrogen volatilization and leaching loss. Phosphorus and potassium fertilizer should be applied on the basis of soil measurement, and microelements should be applied in a targeted way.

Organic fertilizer arises at the moment, organic fertilizer production process: chicken and pig feces as the main raw materials, add a certain amount of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances, to rice bran, yeast, soybean meal and sugar fermentation for a certain time as biological bacteria, under the action of sulfuric acid, mixed fermentation to produce biological fertilizer, now in the production has been widely used.

A large amount of manure and waste from cattle farms are directly discharged into the agricultural ecosystem, causing extreme deterioration of the ecological environment and other problems that urgently need to be solved locally. Manure contains rich organic matter and nutrients, which are essential nutrients for crop production.

What are the required configurations for an annual production line of 30000 tons of organic fertilizer in a cattle farm?

1. Hydraulic tank flipping machine: Its equipment is used for fermenting and flipping materials, with advantages such as high accumulation of fermenting materials, large flipping output, and thorough flipping of materials. It is suitable for large-scale organic fertilizer fermentation, especially for organic fertilizer manufacturers with high land costs.

5 drum dryer: Its equipment function is to further remove the moisture contained in the processed material particles to meet the moisture content standard.

6. Rotary cooler: The function of this equipment is to cool dry granular materials. Due to the high particle temperature of dry materials, they are not easy to store and require cooling for processing. The cooled particle materials are easy to store and maintain quality.

7 drum screening machine: The particle material produced from the granulation program may have certain differences in size, requiring a screening machine for secondary crushing.

8 Packaging machine: The function of this equipment is to wrap the surface of material particles in a thin film, which is conducive to strengthening the shape of the particles. The appearance is very good, and the surface is very smooth.

After weighing and packaging, the automatic packaging scale is controlled by a microcomputer and can achieve multi range measurement. It has high weighing accuracy, automatic packaging, sewing packaging, automatic peeling weight, and detection functions. Its advantages are incomparable to manual packaging.

Organic fertilizer products can be made into granules or powders, depending on market demand. In order to balance nutrition, suitable for transportation and storage, more people choose to process it into granules.

Organic fertilizer production line fermentation animal manure to make organic fertilizer is aerobic fermentation, does not need to be closed, requires oxygen participation, release energy in fertilizer in advance, avoid burning roots during planting. The special bacteria of cow manure organic fertilizer can decompose various animal manure quickly, release the heat in fertilizer, and prevent the occurrence of root burning. After treatment with organic fertilizer equipment, macromolecular nutrients in manure that are not easy to be absorbed by plants can be decomposed by microorganisms. Decompose into more absorbable small molecular elements, improve fertilizer utilization. At the same time, the composting process can kill bacteria, eggs and parasites in the fertilizer, cutting off the source of pests and diseases. Cow manure organic fertilizer has the following characteristics:

1, improve the soil, fertilize. After organic fertilizer is applied into the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, make the soil mature, enhance the soil fertilizer retention ability and buffering ability, and create good soil conditions for the growth of crops.

2. Improve fertilizer utilization rate. Organic fertilizer contains more nutrients, but the content is relatively low, and the release is slow, while fertilizer has high per unit nutrient content, less components, and the release is fast. The two applications are reasonable and complement each other. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients and fertilizers in the soil. Organic fertilizer and chemical fertilizer promote each other, which is beneficial to crop absorption and improve fertilizer utilization rate.

3. Increase production and improve quality. Organic fertilizer contains rich organic matter and a variety of nutrients to provide nutrients for crops. After the decomposition of organic fertilizer, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote crop growth and improve the quality of agricultural products.

Regardless of the history of fertilizer, biological fertilizers such as cow manure and organic fertilizers continue to advance. Microorganisms have the function of providing plant nutrition (such as nitrogen fixing genes, etc.), but they may not have the ability to decompose pollution (that is, genes that decompose substances).

Roller extrusion granulator is an improved product of the new technology of international organic fertilizer granulator. The machine is equipped with a machine touch assembly of the pre-continuous feeder and the forced feeding screw feeding hopper connected to the feeding system, ensuring the continuous feeding, abundance and symmetry, which is a crucial step. The uniform arc groove carved on the pair rolls is beneficial to the material biting into the roll, resulting in the arc groove sealing cavity (belt), but also beneficial to the material compaction, reduce the forming pressure of the mechanism and the load of the main engine, and improve the granulation rate.

The key structure of the roller pelletizer is the roller and the mold. The belt and pulley are driven by the motor and passed to the drive shaft by the reducer. The open gear works synchronously with the passive shaft. The material is added from the hopper, extruded by the pair of rollers, demoulded into balls, driven by a pair of chains, and sent to the crushing screen.

Poultry and livestock manure, straw and other materials contain harmful bacteria. After high-temperature fermentation, harmful bacteria can be killed and the occurrence of underlying diseases can be reduced. Grass seeds are often found in the feces of poultry and livestock, especially cattle and sheep. If applied directly, grass seeds can lead to overgrowth of weeds. After high-temperature fermentation, it can kill the rapeseed in the fertilizer. When unfermented materials are applied to the soil, they will automatically begin to ferment, and the high temperature generated by fermentation can cause root burning in crops. Completely decomposed materials will not increase in temperature and can be safely applied to the soil.

Composting is the process of mixing poultry and livestock manure, straw, agricultural and forestry waste, and adding fermentation agents to make the materials undergo fermentation and maturation.

Why use organic fertilizer composting machines for large-scale composting

For safety reasons, currently, aerobic fermentation is mainly used for composting. Aerobic fermentation, as the name suggests, requires oxygen and ventilation during the fermentation process. Moreover, during the fermentation process, the temperature of the pile will increase due to the action of high-temperature bacteria. In order to prevent the beneficial bacteria from evaporating at ultra-high temperatures, it is also necessary to periodically flip the materials.

To produce organic fertilizer on a large scale and continuously, at least 10 tons of new materials are added every day. To evenly flip 10 tons of materials, at least 4 workers need to work continuously for 2 hours. Pure manual flipping greatly increases labor costs.

Fortunately, with the development of the machinery industry, organic fertilizer composting machines have been born. The flipping and throwing of 10 tons of material, allowing the machine to dry, may only take 2 minutes, greatly saving labor costs and time. And if the fermentation site is limited, the height of the compost can be increased to 2 meters, and using an organic fertilizer composting machine can still fully flip the material.

When choosing organic fertilizer equipment, facing the classification of organic fertilizer granulator, we do not know what is appropriate to choose. The following details are introduced for reference. The fundamental difference lies in the selection of appropriate granulation methods according to the requirements of the use of materials. Mainly divided into dry method and wet method two categories:

Dry process

Mainly refers to the relatively low moisture content of the material products. Typically, moisture content below 10% is the zero threshold. (There are also very few materials can reach 16%, such as: some materials themselves only contain crystallizing water) dry granulation is mostly irregular particles (such as: ordinary granular potash fertilizer) or more general, similar shape of small gravel. With the current domestic industrial upgrading and environmental protection requirements more and more strict, many chemical building materials powder need to be made into particles.

Wet process

There are many kinds of wet granulation equipment and methods for materials with moisture content above 20%. Such as: disk granulation, drum granulation, spiral granulation, these methods have been used for many years, with the use of different materials of the environment and processing requirements of continuous improvement and continuous improvement, has made great progress. Such as organic fertilizer granulation popular in recent years, its particle size is mostly between 1mm-6mm, the above method is used.

Organic fertilizer granulator medium – dry granulator has lower energy consumption and more environmental protection than wet granulator. No need to dry, no water and binder, so will not change the performance of the material; This is also the dry method in the organic fertilizer production line. Granulation has several advantages over wet granulation. More suitable for industrial mass production. Another situation is that the particle size of some materials is relatively small, and the products between dozens of mesh and one hundred mesh can also be reduced by air flow, spray, flash drying and other methods.

Organic fertilizer equipment is now a good project for many people, because organic fertilizer equipment conforms to national environmental regulations and is a kind of environmental protection machinery. So, how to buy a suitable granulator according to their own needs?

1. Determine the size of the organic fertilizer equipment: for example, how many tons per year, or how many tons per hour.

2. Determining the shape of the particle means choosing which granulator to use: powder, column, oblate or standard round.

3. Determine the configuration level of organic fertilizer equipment: the configuration level is different, the price of organic fertilizer equipment is different, the number of labor force is different, the stable and high yield of organic fertilizer equipment is different, and the price of organic fertilizer pelletizer is different.

4. Determine the level of environmental protection requirements: places with low environmental protection requirements generally choose to reduce dust and invest little in organic fertilizer equipment; In places with high environmental protection requirements, heavy dust removal and ink dust removal are generally selected to meet the national air emission quality standards.

Pelletizer equipment includes npk fertilizer granulator, drum granulator, flat mold granulator, new organic fertilizer granulator, plate granulator, etc. For example, a roll extrusion granulator is a molding machine that shapes a material into a specific shape. The roller extrusion granulator has a particularly good granulation effect on ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. Granulation rate can reach 85%, without drying, less investment, quick effect.

The organic fertilizer granulator consists of several parts. First, it is a collection of devices. Secondly, it is the most important transmission component, but also has a special technology of support device. Finally, the conveyor belt and training wheels. Maintaining equipment is very important. Dust on the device must be cleaned locally to prevent dust from entering the machine. If the bearing temperature is too high, the parts need to be checked regularly to prevent excessive wear and tear.
