The double roller granulator is a patent product newly developed by Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. It adopts dry extrusion granulation and new process design and manufacture. The double roller granulator can not only granulate a variety of organic matters, but also can ferment the coarse fiber materials which are difficult to granulate with conventional equipment, such as crop straw, wine residue, fungus residue, drug residue, animal manure, etc In addition, the granulation effect of humic acid and municipal sludge is very good.
Technological process:
The double roller granulator is driven by a motor, and the drive belt is transmitted to a pair of high-pressure rollers with sliding shell through the reducer to do relative work.
The two rollers of the fertilizer granulation machine interact with each other by a group of split gears. The two rollers are directly driven by two output shafts of a special reducer to achieve the purpose of extrusion molding.
During production, the raw materials are fed into the hopper, and are extruded by the high-pressure roller body. After demoulding, the raw materials flow to the crushing workshop at the bottom of the roller body.
The power of crushing and forming is that the sprocket of the active roller shaft is driven by the chain to a pair of crushing rollers for relative movement. After crushing and screening in the working room, the finished product particles will flow out of the machine through the screen.
