Reason: There are hard blocks or small iron blocks mixed in the conveying material, causing the cutter to get stuck, causing a sharp increase in current and burning the motor; Excessive material, motor overload, heating and burning

 

 

 

Solution:

 

 

 

① Prevent small iron blocks from entering;

 

 

 

② Maintain a certain gap between the blades and the casing;

 

 

 

③ Material balance;

 

 

 

④ Send all the materials before stopping the machine.

 

 

 

2. Screw conveyor casing shaking

 

 

Reason: During installation, the centerline of each spiral joint is not concentric. During operation, the eccentric jamming causes the shell to shake.

 

 

 

Solution:

 

 

 

Align the centerline during reinstallation.

 

 

 

3. Excessive temperature rise of suspension bearings

 

 

 

Reason: Improper installation of the position; Abnormal friction of the connecting shaft caused by the mixing of hard large objects into the machine.

 

 

 

Solution:

 

 

 

① Clean the foreign objects and test the machine until it is normal

 

 

 

② Adjusting the position of the suspension bearings

 

 

 

4. Overflow of screw conveyor

 

 

 

Reason: The material has high moisture, which accumulates on the spiral suspension bearing and gradually thickens, making it difficult for the material to pass through; Sundries in the material cause blockage of the spiral hoist bearing; The transmission device malfunctioned and was not detected in a timely manner

 

 

 

Solution:

 

 

 

① Stop the machine and clean the debris inside

 

 

 

② Strengthen the drying of raw materials;

 

 

 

③ Stop the machine and repair the transmission device.
