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. The machine has the advantages of simple operation, high material precision, adjustable material ratio, high efficiency, energy saving, easy installation and mobility.
Vertical mixer is a kind of fertilizer mixer which is mainly used for mixing raw materials. The machine is made of polypropylene plate lining or stainless steel plate, which is not easy to stick and wear resistance. The cycloidal pinwheel reducer has the advantages of compact structure, convenient operation, uniform mixing and convenient unloading and conveying.
3,Rotary Drum Granulator
Rotary 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. Rotary Drum Granulator is the key machine of the NPK Fertilizer Production Line.
4,Drum Fertilizer Dryer
Fertilizer Drying Machine is mainly used to produce compound fertilizer and dry a certain temperature and granularity of fertilizer. On the other hand, it also can be used for drying other materials.
5,Drum Fertilizer Cooler
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.
6,Rotary Screener Machine
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.
8,Automatic Packing Machine
This machine is mainly used for automatic quantitative packaging of powder materials, such as, flour, starch, feed, food, chemical industry, light industry, building materials industries.
Advantages of NPK Fertilizer Production Line:
1. Raw meterials are extremely versatile
2. It has a high balling rate and the survival rate of biological bacteria.
3. It has a short process flow
