Introduction and application of vacuum kneader

Vacuum kneader is an important series of kneaders. It is mainly used in chemical production fields that are prone to bubbles such as rubber. The domestic industrial chain has been very mature.

The working principle of vacuum kneader is also that two blades produce shear, so that semi dry or viscous plastics can be quickly and evenly mixed and stirred.

The vacuum kneader adopts water cooling, steam, electric heating and other methods to adjust the temperature through hydraulic cover opening and cylinder turnover. The discharging methods include screw extrusion, dumping, hydraulic pressure, etc. In order to ensure the quality, the cylinder block and blade in contact with materials are mostly made of stainless steel.
