Production does not meet the requirements

Reasons:
- The hardness or toughness of the material exceeds the best crushing range of the machine
- The power cord of the motor is incorrectly connected, causing the jaw to rotate in the opposite direction
- The size of the discharge opening is lower than the specified value
- displacement of the jaw plate, the teeth grooves of the movable and fixed jaw plates are relative and in the wrong position
- low voltage;
- Rotation of the moving jaw body and the outer ring of the bearing on the eccentric shaft (this situation rarely occurs)

Solutions:
- Replace the suitable type of jaw crusher
- Adjust the motor power wiring to use triangle connection
- Adjust the size of the discharge opening or add a fine jaw crusher
- adjust the jaw plate position to make the tooth groove bite or replace the compliant Jaw plate
- Add voltage converter and regulator
- Replace bearings/ moving jaw body
