Kneader uses a pair of mutually matched and rotating blades to produce strong shear action to make semi dry or rubber like viscous plastic materials react quickly, so as to obtain uniform mixing and stirring. The speed of the two blades is different. Different speeds can be set according to different processes. The most common speed is 42 / 28 rpm. Therefore, the pressure requirements of kneader are very high. When the pressure is insufficient, the following problems occur:

1、 The motor coupling is worn and needs to be checked or replaced.

2、 The steering of hydraulic pump or motor is incorrect, which needs to be checked and handled.

3、 If there is a problem with the shockproof device, it needs to be checked and fastened or replaced with a new shock absorber.

4、 The key on the transmission shaft of the motor or hydraulic pump is cut and needs to be checked.
