Double Roller Extrusion Granulator

The double roller extrusion granulator is the key equipment of compound fertilizer granulation and has the characteristics of advanced technology, reasonable design, compact structure, novelty and utility and low energy consumption; it is equipped with corresponding equipment, which can form a small production line, thus forming the continuous production of certain production capacity and mechanization production. The machine adopts the eugenic formula without drying and produce fertilizer by normal temperature; the product once rolled and formed, meeting the requirements of technical specifications of compound fertilizer. Therefore, it is the upgraded machine for the production of high, medium and low concentration special compound fertilizer and the renewable energy consumption of the compound fertilizer industry.

Working Principle

This series of roller granulation is extruded model, and its working principle is: Electromotor drive the belt and pulley, then it is transmitted to the driving shaft by the speed reducer, and by synchronizing the open gear with the passive shaft, achieving the working in the same direction. Material is added from the hopper, after the roll extrusion forming, demoulding pelletizing; and through a chain, the balls are transferred to the broken screen studio, sieving and isolate the finished products (the balls), then return to mix with new materials and granulate again.

1.Adjustable Pressure: Operators can adjust the pressure between the rollers to control the size, density, and hardness of the granules produced. This flexibility allows for customization according to specific fertilizer formulations and application requirements.

2.Reliable operation and low cost. The machine’s power is small, and operation is reliable; it has no three waste discharge, the operation is stable, and the maintenance is convenient.

3.The raw materials have wide applicability. It can be used for the granulation of various raw material, like compound fertilizer, medicine, chemical industry, feed, coal, metallurgy.

4.Low Moisture Content: The extrusion process typically results in granules with low moisture content, reducing the need for additional drying processes and improving the overall efficiency of the production line.
