1) The belt and pulley are driven by the electric motor and transferred to the active shaft through the reducer.
2) Synchronized with the passive shaft through the pair of open gears, and the two roller skins work in opposite directions.
3) The material is added from the feeding hopper, and is extruded and shaped by the rollers, and stripped for granulation.
4) The material passes through a pair of chains and is transferred to the crushing and screening room to screen down and separate the finished pellets.
5) Then the return material is mixed with the new material and granulated again.
6) With the continuous rotation of the motor, the materials are continuously entering before the mass production can be realized.
1) Carbon steel plate rack
2) Transmission (i.e. gears)
3) Double roller orking device
4) Crushing and separating device
1) Efficient Production: The high speed rotation and squeezing action of the rollers during processing of the double roller granulator can quickly convert powder raw materials into fertilizer granular products without the need to add water or steam.
2) Flexibility and adjustability: the double roller granulator can be adjusted and controlled according to different raw material characteristics and product requirements. Parameters such as roller speed, pitch and surface shape can be adjusted to obtain the desired particle form and size.
3) Wide application: it can produce fertilizer pellets, solid feed pellets, granular pesticides, herbal pills and so on. Its flexibility and adjustability make the double roll granulator an indispensable powder processing equipment in many industrial and agricultural fields.
To summarize, double roller granulator is widely used for its advantages of high quality granular products, high efficiency production capacity, flexibility and adjustability, energy and resource saving. It is an important processing equipment that provides high quality granular products for various industries.
1) Make sure there is no hard materials in the raw material
2) Regular maintenance
3) Use lubrication oil
4) Put in the raw materials equably
5) Clean the cooling pipe regularly
