Annual output 20,000-30,000 tons extrusion granulation fertilizer production line

Nitrogen, phosphorus and potassium, which are the major nutrients in soil, cannot meet the needs of crop growth, so fertilizers containing nitrogen, phosphorus and potassium are needed to supplement them. Fertilizer can not only improve soil fertility, but also is an important measure to improve crop yield per unit area.Fertilizer is the most fundamental and important material input in agricultural production.
This annual output 20,000-30,000 tons extrusion granulation fertilizer production line, can achieve 8 tons of output per hour, realize the commercial plant production of fertilizer, and meet agricultural needs.

Fertilizer machinery of Annual output 20,000-30,000 tons extrusion granulation fertilizer production line
This system adopts computer scales for automatic control, and uses pneumatic valves to control the main material warehouse for quantitative feeding. 

It is mainly used for crushing and pretreatment of materials before granulation. Its function is to process the bulk materials into the required medium fine powders for fertilizer granulation.

The machine is mainly used for the mixing of raw materials. Therefore, it is not easy to stick to the material and wear resistance. The colloidal-pin wheel reducer has the characteristics of compact structure, convenient operation, uniform mixing, and convenient discharge and transportation.

According to the many years of our factory production experience, the roller press granulator is a new type of equipment developed on the basis of the original double roll extrusion granulation. The machine has compact structure, good stability, good sealing, low noise, easy operation and maintenance, etc. The new machine has won the users praise after coming into the market. Wide adaptability for raw materials, such as fertilizer, feed, chemical industry, and especially good adaptability for rare earth, metallurgy, coal, biological agent, environmental protection project.
Simple machine structure.
Easy operation and maintenance.
Low power consumption.
Once forming, no drying process, normal temperature granulating.

The screen cylinder rotates at a certain speed, and materials are separated from top to bottom through the screen cylinder. Fine materials are discharged from the lower part of the front end of the screen cylinder, while coarse materials are discharged from the lower end of the screen cylinder.Drum screen is equipped with beating device, in the process of screening, the relative movement of beating device and screen cylinder can achieve the effect of uninterrupted cleaning of screen body, so that the screen cylinder in the whole process of work always keep clean, not sticky, not blocked, does not affect the screening effect.

The machine is composed of a host, transmission belt, sewing machine, controller, to ensure humanized operation, reduce labor intensity, the use of high stability, high precision weighing sensor, accurate and stable measurement. Manual assistance on bag loading, automatic weighing, bag clamping, filling, automatic sealing or sewing through conveyor belt transfer.

The Annual output 20,000-30,000 tons extrusion granulation fertilizer production line is suitable for investment and construction of small and medium-sized enterprises. There is no drying process in the extrusion granulation fertilizer production line. At the same time, the material return ratio is low, the process flow is simple and the investment is low. Low risk, earnings fast, is a good choice for fertilizer production.
