200 tons per day combination granulation fertilizer production line

The main raw materials of the production line are chicken manure, cow manure and other animal manure, green manure, sea manure, cake fertilizer, etc. to produce organic compound fertilizer granules. The production line is divided into pretreatment part and granulation production part.
The raw material is powdered organic fertilizer after pre-treatment. Processing equipment: compost turning machine, organic fertilizer half-wet material crusher, drum screener and other equipment.
Granulation production equipment: mixer, fertilizer granulator, rotary dryer, rotary cooler, drum screener, coating machine, automatic weighing packaging machine. Through the organic fertilizer production line, livestock and poultry manure, straw, rice husk, biogas sludge, wine residue, vinegar residue and other wastes are processed into organic fertilizer. It can reduce environmental pollution and turn waste into treasure.

Organic-inorganic compound fertilizer
Organic-inorganic compound fertilizer is a kind of compound fertilizer which contains both organic matter and appropriate amount of chemical fertilizer. It is a kind of fertilizer which is made by mixing and granulating organic fertilizer and adding appropriate amount of fertilizer, humic acid, amino acid or beneficial microorganism. The inorganic nutrient part is mainly chemical fertilizer.
1. Organic-inorganic compound fertilizer has a variety of nutrient elements, the nutrient distribution ratio is reasonable, the fertilizer efficiency and utilization rate are relatively high. According to the nutrient status of different types of soil and the characteristics of crop fertilizer requirement, a series of special fertilizers can be prepared, with strong pertinence and remarkable fertilizer efficiency.
2. It has certain compressive strength and granularity, good physical properties and easy application.
3. It can improve the absorption efficiency of nitrogen, phosphorus and potassium, balance the content of nitrogen, phosphorus and potassium, and contain a large number of beneficial bacteria, which can play the role of nitrogen fixation, phosphorus and potassium dissolution, promote the absorption of nitrogen, phosphorus and potassium, and improve the absorption rate of nitrogen, phosphorus and potassium.
combination granulation fertilizer production line
The fine powder material is mixed and granulated in the machine by using the mechanical stirring force of high speed rotation and the aerodynamic force generated therefrom, so as to achieve the purpose of granulation. The shape of the particles is spherical. The diameter of the particles is generally between 0.3-3 mm, and the granulation rate is not less than 90%. The size of particle diameter can be adjusted by mixing amount of material and spindle speed. Usually the smaller the mixing amount, the higher the speed, the smaller the particle, and vice versa.
Application scope: This machine is especially suitable for granulation of fine powder materials.

Main steps of combination granulation
For many kinds material weighting and send to next machine. Computer automatic control of organic fertilizer, NPK fertilizer, additives, trace elements and so on through the belt scale proportional feeding. The raw materials are evenly conveyed to the belt conveyor in proportion to the formula, which is not only a premixing, but also ensures the accuracy of the formula.
The quality of products can be guaranteed by mixing raw materials well and evenly. Two helical blades rotate relative to each other in the Twin-axis mixer. The powder material is stirred by adding water to make the powder material reach controllable humidity.
Granulation(New Type Two In One Organic Fertilizer Granulator)
Processing powder to granules. In the production of organic fertilizer, the choice of granulation method is very important. The combination granulation fertilizer production line uses a two-in-one organic fertilizer granulator, which is a multi-purpose wet pelletizing equipment.
After granulation, the moisture and strength of the granules are not up to the standard, so it must be dried. After wet material is added to the dryer, the material is evenly dispersed in the dryer, fully contacting with hot air and speeding up the drying speed under the turning of the inner plate reader of the drum.
Dedusting(Cyclone Dust Collector)
Cyclone dust collector is mainly used for pre dust removal and separation and recovery of high concentration dust, widely in fertilizer production, chemical dustry, mining, metallurgy, refractories, building matrials.
The machine is used to cool the hot fertilizer granules. The lifting plate installed on the inner wall of the cylinder constantly turns up the material, and the material loses heat in contact with the air, so as to achieve the goal of uniform cooling.
Primary screening(Rotary Drum Screener)
The screening machine is to sieve a small amount of powder. The remaining particles are ready for secondary screening.
Secondary screening(Rotary Drum Screener)
There are some non-uniform particles, after sieving get the appropriate granules that we need, the small diameter particle can be screened down for twice processing, the bigger granules go to the chain crusher machine for return crushing.
Coating(Coating Machine)
Coating on the surface of fertilizer particles, can effectively prevent the organic fertilizer caking.
Packing(Fertilizer Packing Machine)
Automatic quantitative packaging of powder and granules, suitable for flour, starch, feed, food, chemical industry, light industry, building materials industries.

Economic benefit and prospect of combination granulation fertilizer production line
The composting effect of low cost is not significant, and organic-inorganic compound fertilizer is the best way to use it. The fertilizer processed by the organic compound fertilizer combination granulation production line can significantly improve the nitrogen absorption rate, crop yield and quality, and fertilize the soil. It has broad market prospects, good environmental and social benefits.
