Application of Roller Squeezing Granulator in Compound Fertilizer Production Line

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 co use of organic fertilizers and fertilizers in organic fertilizer production line processing

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.

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

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.

Advantages of organic fertilizer production line in producing cow manure organic fertilizer

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).

The advantages of roller extrusion granulator in fertilizer granulation production line

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.

Why use organic fertilizer composting machines for large-scale composting

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.

Organic fertilizer granulation machine processing dry and wet two types of granular organic fertilizers

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.

How to Choose and Maintain Organic Fertilizer Granulators Correctly in Chicken Farms

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.

The process flow of producing organic fertilizer from pig manure organic fertilizer production line

Pig manure has a high nutrient content and can improve soil fertility after use. The problem of fecal pollution in large-scale pig farms has attracted strong social attention. Under environmental pressure, more and more farms are starting to solve it, attempting to change the current passive situation. Practice has proven that using pig manure to produce organic fertilizer is a relatively effective harmless treatment and resource utilization method for large-scale breeding farms.

The process flow of producing organic fertilizer from pig manure organic fertilizer production line

Crush, mix, and mix various raw materials such as composted pig manure organic fertilizer, nitrogen, phosphorus, potassium inorganic fertilizer, and other additives in proportion.

The organic fertilizer granulator is suitable for direct granulation of pig manure organic fertilizer after fermentation. Before granulation, the raw materials do not need to be dried, and after crushing, the raw materials can be directly mixed to produce spherical pig manure organic fertilizer particles. The moisture content of the raw materials can be between 30% -40%, and the pelletizing rate can be above 96%.

The pig manure organic fertilizer pellets output from the granulation system have certain differences in particle size and need to be screened and graded. The selected rotary screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device. It is recommended to equip an automatic feeding system to screen out unqualified large and small particles, transport them out through a belt elevator, re crush them, and send them to a granulator for further granulation, which helps to improve the continuous operation capacity of the production line.

The function of the pig manure organic fertilizer dryer is to further remove moisture from the screened pig manure organic fertilizer particles and meet the standard requirements for organic fertilizer moisture content. Particle drying generally uses a drum dryer to improve particle formation while drying.

The dried pig manure organic fertilizer particles are transported by a belt to a cooling machine. The rotary cooling machine is also a rotating cylinder filled with lifting pallets. Under the action of the pallets, the granulated materials are lifted and heat exchanged with the cold air sucked into the cylinder, cooled to near room temperature, further improving particle strength and reducing moisture.

After the pig manure organic fertilizer granules are cooled, they can be used as bio organic fertilizer, compound microbial fertilizer and special organic fertilizer. They can spray attachments to the coating machine through the self-priming spray equipment to improve the appearance or internal quality of the product.

Pig manure organic fertilizer pellets are quantitatively weighed and packaged using an automatic packaging scale. The automatic packaging scale adopts microcomputer control, which can achieve multi range measurement. It has high weighing accuracy, automatic clamping, sewing, automatic tare weight removal, and detection functions. Its advantages are incomparable to manual packaging.
