The rotary drum granulating machine is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, which is suitable for the large-scale production of cold and hot granulation and high-, medium and low-concentration compound fertilizers. This equipment is used to perform necessary operations on the materials to be processed, steam and heating are used to adjust the humidity, which increases the temperature of the granulated materials themselves, reduces the water in the granulation, reduces the load of the dryer, and improves the work efficiency.
Rotary drum granulator for cold and hot granulation.
This machine adopts wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, the material is made by the rotation of the cylinder. The squeezing force generated between the particles reunite into a ball.
First, each basic fertilizer is screened separately, and the screened material is crushed by a crusher and then screened. The under-sieve is sent to their respective hoppers. When the granulation system is in operation, the basic fertilizers are simultaneously sent from their respective hoppers to the feeding hopper via metering equipment, conveying equipment and lifting equipment according to the proportioning requirements. At the same time, the returned material enters the hopper together with the basic fertilizer through the lifting equipment. The basic fertilizers and returned materials are mixed to a certain extent in the process of transportation and lifting, but it is more ideal if a mixing device can be added. The mixture in the hopper is fed to the drum granulator at a certain feeding speed. At the same time, properly pass saturated steam under the material layer, which not only increases the temperature of the material, but also humidifies the material, which is conducive to granulation. If necessary, sprinkle a small amount of water or fertilizer solution on the material to maintain the maximum liquid level of the material to be granulated. The material forms a rolling material bed by the friction generated by the rotation of the drum granulator. The squeezing force generated by rolling makes the material containing a certain liquid phase agglomerate into small particles. These small particles become the core and adhere to the surrounding powder. Form larger particles. Since the drum granulator is generally inclined 1°~2.5° to the discharge end, the pellets slowly roll toward the discharge port while rotating with the cylinder. Qualified pellets leave the drum granulator and then enter the dryer for drying, and then go through screening, cooling, coating, packaging and storage. After being crushed, the on-screen material and the under-screen material are sent to the hopper as the return material and the basic fertilizer is granulated at the same time. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.

What are the main equipments of BB fertilizer production line?
BB fertilizer, also known as mixed fertilizer, is a mixture of single fertilizer (or multiple fertilizer) in a certain proportion. Due to the low investment, high benefit and high precision of blending fertilizer, many customers choose the equipment of blending fertilizer.
BB Fertilizer Mixer Machine
The main equipment of mixed fertilizer is composed of mobile belt conveyor, bucket elevator, electronic automatic batching system, disc feeder and packing scale. BB fertilizer is suitable for dry mixing multiple basic fertilizer with nitrogen, phosphorus and potassium fertilizer by physical method to make mixed fertilizer with multiple fertilizer and single fertilizer. There are many kinds of BB fertilizer, and the raw materials are not the same, so the physical and chemical properties of BB fertilizer are not the same. For example, the particle size is not uniform, the product storage time is short, and different chemical reactions occur between materials, so some finished products are easy to melt in the packaging bag, and even become mud, which will affect the fertilizer efficiency.

Will the moisture content of materials affect the production efficiency of BB fertilizer?
The moisture content is the main factor affecting the production of BB fertilizer. The mass fraction of urea, ammonium nitrate, nitrophosphate, ammonium phosphate and potassium chloride are all less than 3%. There will be no adverse reaction after mixing materials for a long time. However, the moisture content of granular phosphate fertilizer is uncertain, which often causes some adverse effects when it is used to produce BB fertilizer.
It can be seen from table 1 that if ammonium nitrate is used in the production of low concentration BB, the mass fraction of water in granular phosphate fertilizer should be controlled below 5.6%, otherwise the decomposition of ammonium nitrate will be accelerated and the physical and chemical properties of the product will be affected.
We all know that the development of agriculture is inseparable from the help of fertilizer, and there are many kinds of fertilizers. In the past, we often introduced organic fertilizer and chemical fertilizer, but today we have to introduce the related knowledge of potash fertilizer. The production of potash fertilizer is inseparable from the help of potash fertilizer extrusion granulator, just as organic fertilizer cannot do without the help of organic fertilizer equipment. Therefore, we need to pay special attention to the quality of potash fertilizer granulator. Generally speaking, the production of both organic fertilizer and potash fertilizer is inseparable from granulator equipment. Therefore, when producing potassium fertilizer granules, we need to compare the capabilities and characteristics of various granulation processes to select relevant equipment. The key factors to be considered are as follows:
According to the characteristics of different raw materials, different granulation methods should be selected. For consideration of rolling granulation, it is necessary to investigate whether the fineness of the powder is sufficient. If the raw material is too large, it is not suitable to use rolling pelletizing. If we choose granulating, we need to consider whether the original powder is kneaded with water or other liquids. If there is a certain plasticity in the water or other liquids, if the suspension is wet, it is necessary to consider whether atomization is easy. If atomization is easy, spray granulation can be considered, but spray granulation can be used. The thermal sensitivity of raw materials should be considered.

2. Product requirements
According to different granulation methods, the granularity of the products is quite different. For example, the granularity of spray granulation is small, but the rehydration performance is good. However, the particle size of extrusion granulation products is generally larger, and even can be used to prepare pellets. The products obtained by mixing granulation and fluidized granulation are spherical particles with irregular shape. The smoother spheroid can be obtained by rolling. For regular particles with special shape, extrusion and extrusion granulation are needed. For the selection of product particle shape, the process requirements and convenience of use should be considered. Spray granulation can be used when the particle strength is not high or the strength is too high. If the high strength of the particles is required, it is necessary to consider extrusion granulation and add appropriate binder. The porosity and density of the particles also directly affect the strength of the product. It is a pair of contradiction to improve the porosity and strength at the same time. The size of porosity and density can be adjusted to the required index through the process operation parameters.

3. Other factors
The processing capacity of different granulation methods is very different, and the space occupied by equipment is also very different. Therefore, the investment and processing cost of equipment and civil engineering must be considered. Dry granulation will inevitably lead to dust generation. However, wet granulation needs drying after granulation and consumes energy, all of which should be considered in the process design of granulator.
4. Drying method
Many granules need to be dried. There are many drying methods for particles, and the drying equipment can be divided into two categories: dynamic (such as fluidized bed drying) and static (such as belt drying and box drying) according to the movement state of particles in the drying process; according to the discharging mode, it can be divided into continuous (such as continuous fluidized bed drying, belt drying) and intermittent (box drying). When the liquid content is high, the dynamic drying is easy to agglomerate, so the static drying method is suitable. When the liquid content is low and the particles are hard, dynamic drying can be used. The fluidized bed drying has uniform heating and finishing effect, but the yield of finished product is lower than that of box drying. Continuous drying equipment is mainly suitable for large tonnage single variety. For the production of medium and small tonnage and various varieties, the intermittent drying equipment is more suitable.
Organic-inorganic compound fertilizer is a new type of fertilizer made of fermented organic materials such as animal manure and plant residues, adding some chemical fertilizers, and then mixing them thoroughly. It not only has the advantages of inorganic fertilizers with fast fertilizer efficiency, but also has the advantages of organic fertilizers to improve soil and lasting fertilizer effects. It can complement each other’s strengths and complement each other to maintain and improve soil fertility, increase crop yields, improve the quality of agricultural products, and achieve high yield, high efficiency, high quality, and ecological safety. The purpose of application is of great significance for maintaining sustainable agricultural development.
Complete Machines for Organic-Compound Fertilizer Production
In order to accelerate the promotion and application of organic-inorganic compound fertilizer, the following three links must be grasped in actual production:
1. Pre-treatment of organic materials.
Composting Machine for Organic-Compound Fertilizer
The pretreatment process usually refers to the organic fertilizer fermentation process. Fermentation maturity is the quality basis of organic fertilizer. The ideal conditions for fermentation include:
Moisture. Maintaining proper water content is the primary condition for promoting microbial activity and composting fermentation. Generally, the maximum water holding capacity is about 60%.
Ventilation. The use of composting equipment to maintain proper air in the pile is beneficial to the reproduction and activity of aerobic microorganisms and promotes the decomposition of organic matter. When composting at high temperature, attention should be paid to proper accumulation of tightness. In trough fermentation, try to add auxiliary materials according to the process requirements to facilitate aeration.
Carbon to nitrogen ratio.The ratio of carbon to nitrogen for the normal decomposition of organic matter by microorganisms is 25:1. The ratio of carbon to nitrogen in legume green manure is 15-25:1, weeds are 25-45:1, and grass crop stems are 60-100:1.
2. Granulation and drying adjustment.
Organic-inorganic compound fertilizer can be produced by a typical solid agglomerate process, and the process is basically similar to that of chemical compound fertilizer. The difference is that the granulation needs to adopt a rotating drum and a disc two-stage granulation, and drying also requires continuous two-stage drying to make the moisture reach the requirements of particle strength and non-caking. The production of organic-inorganic compound fertilizer also needs to add 30% of organic materials.

3. Requirement of ingredient group.
The mandatory technical standards for organic-inorganic compound fertilizers stipulate that when the nutrient content of (N+P2O5+K2O) is 15-25%, the organic matter content is not less than 20%; when the nutrient content of (N+P2O5+K2O) is greater than 25%, the organic matter content is 15% . Due to its inherent characteristics, organic-inorganic compound fertilizers have a wide variety of organic materials. The factory needs to choose according to local organic resources and must be fully fermented and decomposed. Inorganic nitrogen, phosphorus and potassium must be selected with high nutrient content urea, diammonium phosphate, monoammonium phosphate, potassium chloride, and potassium sulfate. Chemical fertilizers are mostly inorganic salts. If microbial agents are added to organic-inorganic compound fertilizers, the amount of chemical fertilizers added should not be too high, otherwise the activity of microorganisms will be inhibited.
Common organic fertilizer granulators are: dual -roller granulator, drummer granulator, disc particle maker, new organic fertilizer granulator, new two -in -one organic fertilizer granules, flat mold granulator, Each granulator has its own production characteristics, and the price of the granulator is also different.
Rotary drum bio compound organic granulator for cold and hot granulation.
Which granules can be used for NPK production lines?
The disc particle maker mainly uses the rolling of the surface of the disc and the granules of the particles itself, and uses the upper mixture to achieve a high goal rate. The investment cost of granulator equipment is low and the production capacity is strong, but the open -air granular dust is relatively large.
The drummeter is a molding machine that can form the material into a specific shape. The main working method is the granular wetting method. With a certain amount of water or steam, the basic fertilizer can fully react after humidifying in the cylinder. Under certain liquid conditions, with the rotation of the cylindrical body, the squeeze pressure between the material particles is condensed into a ball. The investment cost of fertilizer equipment is high, the production capacity is strong, and the drums are relatively small.
The double -roller granular machine is produced in non -drying normal temperature process, which is formed at one time. The device has less investment, fast results, and good economic benefits. The whole set of equipment has a compact layout, scientific and reasonable, and advanced technology. Energy saving and consumption reduction, no waste discharge, stable operation, reliable operation, and convenient maintenance.
The raw materials are widely adaptable and suitable for raw materials for compound fertilizer, medicine, chemical, feed and other raw materials. A variety of concentrations and types of compound fertilizers (including organic fertilizer, inorganic fertilizer, biofex and magnetic fertilizer) can be produced.
