Question: What is the constant occurrence of knocking sound inside the machine when the jaw crusher is running at high speed?
Reply:
Dear Maryam,
1. The motor wiring position is reversed, the main engine is turned on and off (the clockwise rotation is performed), or the motor is connected in a delta connection to form a star connection method;
2. The jaw plate is displaced, and the top of the tooth is opposite to the top of the tooth;
3. The clearance between the moving jaw and the bearing is too large, so that the outer ring of the bearing rotates relative to each other;
4. The discharge opening is less than the specified limit;
5. The hardness or toughness of the crushed material exceeds the scope specified in the instruction manual;
6. The voltage at the work site is too low.
Regards!
