can be generally divided into: raw material ingredients, raw material agitation, raw material granulation, granule drying, particle cooling, particle grading, finished product coating, and final product packaging.
of the Low Investment NPK Fertilizer Production Line: Batching System, Rotary Drum Granulator, Rotary Dryer, Rotary Cooler, Rotary Screener, Coating Machine, Packing Machine.
It is mainly used for the mixing, batching and feeding of 3-8 kinds of materials. The machine adopts computer scales for automatic control, and uses pneumatic valves to control the main material warehouse for quantitative feeding. After the materials are mixed in the mixing silo, they are automatically sent out by the belt conveyor.
Rotary Drum Granulator
Drum granulator is a kind of fertilizer granulator machine can make the material into a specific shape. Drum granulator is one of the key equipment of the compound fertilizer industry. It is suitable for large-scale production of cold &hot fertilizer granulation line and high and low concentration compound fertilizer line. Main work method for aggregate wet granulation, through a certain amount of water or steam, the basis for fertilizers in the cylinder body after full wet chemical reaction, in a certain liquid under the conditions of the rotating cylinder with campaign, reunion between particles to produce extrusion pressure of material into a ball. The Fertilizer Granulator is a compound fertilizer granulation and also an organic fertilizer granulator
The Angle and distribution of Jan plate of this machine is designed reasonable, and it is reliable in performance. So its high thermal efficiency, uniform drying, cleaning fewer materials, convenient use and maintenance.
This cooler used for the production of compound fertilizer, cool fertilizer with certain temperature and particle size. Use dryer together can greatly improve the cooling rate, reduce labor intensity and improve the quality, further remove moisture, reduce the grain temperature of fertilizer.
Rotary drum screening machine is common equipment in compound fertilizer production, mainly used for separating the returned materials and finished product, also realize the classification of the end products, and even classify the end products.
The complete equipment of rotary coating machine include screw conveyor, mixing tank, oil pump and main engine etc. Which form Liquid coating process. The main engine uses polypropylene lining or acid resistant stainless steel, which effectively prevent the lumps of compound fertilizer.
