Compound fertilizer refers to a type of compound fertilizer that is made solely by chemical methods, with at least two of the three nutrients of nitrogen, phosphorus, and potassium indicating their amounts. Compound fertilizers have the advantages of high nutrient content, fewer side components, and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization efficiency, and promoting high and stable crop yields. But it also has some drawbacks, such as its nutrient ratio is always fixed, and the types, quantities, and proportions of nutrients required by different soils and crops are diverse.

The process flow of small-scale Organic fertilizer production equipment is as follows: Organic fertilizer raw materials enter the semi wet material grinder for grinding after fermentation, and then add elements such as nitrogen, phosphorus and potassium to make the mineral elements contained meet the required standards, and then there is a mixer for mixing, and then enter the Organic fertilizer granulator for granulation, drying after coming out, screening through the screening machine, packaging qualified products, and returning unqualified products to the Organic fertilizer granulator for granulation.

The drum granulator 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, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls.

The drum granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method results in higher ball forming rate, more beautiful particles, and energy saving.

The drum granulator is particularly suitable for granulating lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

The production process of Organic fertilizer is mainly to mix the organic solid waste with water content less than 60% with auxiliary materials (plant straw, etc.), microbial fermentation agents, etc., and make it fully decomposed, sterilized, deodorized and dewatered through pool type aerobic continuous fermentation. The moisture content of the decomposed material is generally 30-35%. After screening and magnetic separation, it can be directly used to produce spherical Manure or powder Manure after further drying. Process introduction: pour the raw materials into the Organic fertilizer mixer for mixing, mix them evenly and then crush them, and then input them into the Organic fertilizer granulator with a belt conveyor; After granulation and forming, it is sent to the dryer for drying, and then sent to the cooler for cooling through the elevator or belt conveyor. The water content reaches below 6%. After cooling, it is screened. Large particles are crushed into fine materials through the return Organic fertilizer grinder, and the fine materials enter the disk granulator. The coarse returned materials enter the granulator after crushing, and the finished products are directly packaged.

The drum screen is a common equipment in the production of Organic fertilizer and compound fertilizer. It is mainly used for the separation of finished products and returned materials, and can also realize the classification of finished products, so that finished products can be classified evenly. Adopting a combination screen, it is easy to maintain and replace. The machine has a simple structure, convenient operation, and stable operation.

What are the characteristics of drum screening machines?

The drum screening machine is a relay operated vibrating screen, which is a new generation of self-cleaning screening equipment after the ordinary mesh drum screening produced by major domestic companies. It is widely used for screening various solid materials with particle sizes less than 300mm. It has many characteristics such as high screening efficiency, low noise, small dust emission, long service life, small maintenance volume, and convenient maintenance. Its screening capacity is 60 tons/hour to 1000 tons/hour. The comprehensive utilization of electricity (mainly circulating fluidized bed boilers), which mainly burns low-quality coal, has rapidly emerged in China. Fuels mainly composed of coal gangue and coal slurry often have characteristics such as stickiness, wetness, dirt, and impurities. The coal conveying system generally suffers from clogging of the screening machine, low screening efficiency, high crusher wear, and high energy consumption.

When installing the new two-in-one agitator granulator, pay attention to:
1. Selection of installation location
The new two-in-one agitator granulator should be installed on a horizontal concrete foundation. For safety reasons, the organic fertilizer granulator should be further reinforced with anchor bolts. During installation, the main body of the new agitator two-in-one granulator should be kept perpendicular to the horizontal plane. After installation, further inspection should be carried out, including whether the bolts in all parts are fixed, The situation should be reinforced in time to ensure that all parts are installed.

2. Preparation before operation
When the power supply of the new type agitator two in one granulator is configured, it should be selected according to the power of the organic fertilizer granulator itself. After checking and confirming that there is no problem, carry out no-load test run. The test run is normal and can be put into production.
3. Use and maintenance of organic fertilizer granulator
In the maintenance of the new type of two in one granulator, pay attention to the selection of lubricants, because good lubricants have a great impact on the life of bearings, and the use of poor lubricants is prohibited. Generally, the parts requiring sealing and oiling include rotating bearing, roller bearing, all gears, movable bearing and sliding plane. Regular and regular inspection shall be carried out. Once problems are found, maintenance shall be carried out in time. If there is abnormal sound during use, production shall be stopped immediately to avoid safety accidents.

The new organic fertilizer granulator has a wide range of applications, especially for the granulation of light and fine powder. The finer the basic particles of fine powder materials, the higher the degree of sphericity of the particles, and the better the quality of the particles. Generally, the particle size of the material before granulation must be less than 200 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. Due to the particularity of the granulation of municipal solid wastes such as livestock manure, organic fertilizer, degummed fertilizer, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes and microorganisms, the particles are irregular.

At present, there are many kinds of Manure products on the market, and their production processes are also diverse. Different production processes have their own advantages and disadvantages. Among them, the extrusion granulation process is simple, easy to operate, zero discharge of “three wastes”, high automation, large output, and the product is not easy to agglomerate. It stands out from many processes and is increasingly favored by enterprises.

The granulation characteristics of the roller extrusion granulator: Extrusion granulation is a dry granulation process in which solid materials rely on external pressure to agglomerate. The material particles are close together under high pressure, and the generated molecular force, electrostatic force, and other forces cause the particles to tightly bond together. Common extrusion granulation methods include roller extrusion granulation, spiral extrusion granulation, and disc die extrusion granulation.

The process of roller extrusion granulation machine: The roller extrusion granulation process adopts German roller compression granulation equipment, which uses the strong pressure generated by the roller press to instantly extrude the powder material into shape, and then obtains qualified products through crushing, screening and other processes.

The working principle of the roller extrusion granulator: After materials with different physical properties are reasonably matched and metered and mixed, they are transported by a bucket elevator, adjusted for humidity, and distributed by an automatic feeder into a pair of reverse rotating roller presses. Under the extrusion of the rollers, they form regularly shaped pieces of material, which are then crushed, screened, polished, and anti caking processes to achieve uniform particle size and hardness standards Compound fertilizer products with full particles.

The roller extrusion granulator is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. Adopting the eugenic formula, without drying, produced at room temperature, the product is rolled and formed in one go, ensuring that the product quality meets the technical requirements of compound fertilizers. It is an updated product for the production of high, medium, and low concentration specialized compound fertilizers for various crops and the energy-saving and consumption reduction of the compound fertilizer industry.

With the rapid development of large-scale and intensive poultry, duck, pig, sheep, and cattle farming, the environmental pollution problem caused by the concentrated discharge of manure from breeding farms is becoming increasingly prominent. If there is a lack of effective treatment methods, a large amount of fecal accumulation can easily cause serious pollution. Stacking on the ground, using a ground tipping machine, or feeding materials in a fermentation tank, or using a trough tipping machine. Evenly sprinkle the bacterial agent, ferment in a pile to reach a temperature rise, eliminate odor, decompose, kill miscellaneous bacteria and grass seeds, ferment for 7-12 days, and the number of times the pile is flipped varies depending on the temperature in different regions. Completely ferment and decompose, and leave the pool.

What equipment is needed for making granular Manure from manure processing equipment of breeding farms

1. Organic fertilizer dumper: industrialized fermentation treatment of organic solids such as animal manure, domestic garbage, sludge and crop straw. This equipment conducts comprehensive fermentation on the uniformity of fermentation materials. This allows the front of the fermentation tank to be freely fed or taken out, and waste such as feces can be retained for a long time.

2. Semi wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. Utilizing high-speed rotating blades to crush fibers with good particle size and high efficiency. The semi wet material grinder is mostly used in the production and processing of Manure. It has good effect in crushing chicken manure, humic acid sodium and other raw materials.

3. The Organic fertilizer mixer has fast mixing speed and good uniformity. It can mix 30% viscous materials with liquid. When it works, two rotors with opposite rotating blades stir in the middle. Due to the multiple special angles of the blades, regardless of the shape of the material. What is the size and density. Can mix quickly and effectively. Adopting a lower door for fast unloading speed and minimal residue.

4. Granulation: the selection of granulation mode is very important in the production of Manure. The production of granulators of various models and specifications, disc granulators, Manure agitating teeth granulators, new type agitating teeth rotary granulators, and Manure granulators has the advantages of uniform granulation particles, stable performance, and long service life, which can produce both Manure and inorganic fertilizer and organic inorganic compound fertilizer. The disc granulator is selected for this process.

5. Drying: Although most of the materials after granulation have already formed particles, the moisture and strength of the particles do not meet the standards, and drying treatment must be carried out. A rotary dryer is a rotating cylinder filled with lifting plates inside. Under the action of the plates, the material is fully lifted to exchange heat with the hot air generated by the hot air furnace. As a result, the temperature of the material is raised, and the moisture in it will quickly diffuse outward due to the temperature and steam partial pressure difference. The diffused moisture is carried away by the wind, achieving the effect of drying the material and improving its strength.

6. Cooling: The dried material is transported to the cooling machine through a belt, and the rotary cooling machine is also a rotating cylinder filled with lifting plates inside. Under the action of the plates, the granulated material is lifted and exchanged with the cold air sucked into the cylinder for heat exchange, cooling until it is close to

Each configuration of fecal fertilizer processing equipment varies. The low configuration of fecal fertilizer processing equipment only requires a crusher, mixer, granulator (optional), screening machine, and packaging machine. Therefore, the price of the whole set of Manure production line varies from tens of thousands to hundreds of thousands.

Organic fertilizer granulator is mainly used to granulate organic fertilizer to form fertilizer granules of various specifications, which is convenient for packing and transportation. So what is the need for it?

Organic fertilizer granulator is a member of the organic fertilizer production equipment. Its purpose is to make the organic fertilizer into uniform granules, and to make fertilizer granules of various sizes and sizes according to the actual needs of customers.
Due to the increase in the use of organic fertilizer in agriculture, the use of chemical fertilizer has been reduced. To a certain extent, the soil has been kept in a more healthy state and sustainable development. The raw material of organic fertilizer comes from animal feces collected by animal farms. Combined with the crushing of plant straw, the organic fertilizer we want is produced by fermentation. It not only solves the pollution problem of animal manure, but also carries out green environmental protection production to the end.

The necessity of organic fertilizer granulator is reflected in the convenience of packing, weighing, storage and transportation, so as to make the organic fertilizer more weighing and quantitative. If you still have something you want to know about, please contact Tianci heavy industry.

Powdery organic fertilizer is crushed on the basis of fermented organic fertilizer, and the processing of organic fertilizer requires a complete set of equipment. The complete set of organic fertilizer equipment includes a fermentation reactor, a semi wet material crusher, a horizontal mixer, a drum screening machine, and a belt conveyor. These equipment can form a simple organic fertilizer production line, and the produced organic fertilizer is powdery organic fertilizer. The production process of powdered organic fertilizer mainly involves fermenting and maturing the raw materials, crushing them with a crusher, and finally using a drum screening machine to remove impurities. Finally, they can be packaged into bags. The price of powdered organic fertilizer processing equipment is around 150000 yuan.

3. Another production process of organic fertilizer is granular organic fertilizer. The organic fertilizer produced by the production line of granular organic fertilizer is granular, and the market price of granular organic fertilizer is about 600-1500 per ton. The required equipment includes: fermentation tipping machine, feeding silo, crusher, mixer, granulator, dryer, cooler, screening machine, packaging machine, and belt conveyor. The production process of granular organic fertilizer is based on the granulation of powdered organic fertilizer, so it is necessary to add organic fertilizer granulation equipment. Before granulation, the water content of the raw material is often increased, so the granulation rate is high, Therefore, the organic fertilizer that has been granulated contains a certain amount of water, which needs to be further processed through equipment such as an organic fertilizer dryer and organic fertilizer cooler. Then, qualified particles are screened using a drum screening machine to complete the entire process of granular organic fertilizer. The starting price of small granular organic fertilizer processing equipment is around 350000 yuan.

The disc organic fertilizer granulator can be used for powder, uniform and viscous materials. The materials are transported to the rotating disc of the granulator, and the appropriate amount of water is sprinkled on the materials. Through the centrifugal force of the disc and the friction force in the material rotation, plus the gear rotation structure, the materials can be continuously kneaded and squeezed, and the particles can be formed quickly. At the same time, due to the role of centrifugal force, the particles formed are also very uniform.
The reducer and motor of disc organic fertilizer granulator are driven by flexible belt, which can start smoothly and slow down the impact force. The bottom of the plate is reinforced by a number of radiation steel plates. The thickened, weighted and solid base design does not need to be fixed by anchor bolts, and the operation is stable. The main gear is quenched with high frequency, and its service life is prolonged. The extension of life also means the reduction of production cost.

As the main equipment of fertilizer granulation, the quality of the organic fertilizer machine must be guaranteed. In addition to the manufacturers, the follow-up maintenance depends on the user’s own care and care during daily use, regular maintenance, regular inspection of equipment parts and accessories to see if they are loose or cracked. When they are not in production, they should be cleaned up in time, and they should be added when they are used again Lubricating oil.
