Fault and troubleshooting of jaw crusher:
1. Causes of bearing overheating: insufficient lubricating grease; Excessive lubricating grease; Dirty and deteriorated lubricating grease; Bearing damage. Troubleshooting: Add an appropriate amount of lubricating grease; The lubricating grease inside the bearing should be 50% of its space volume; Clean the bearings; Replace the lubricating grease; Replace the bearings.
2. Reason for excessive discharge particles: excessive wear on the hammer head; The sieve bar is broken. Troubleshooting: Replace the hammer head; Replace the sieve strip.
3. Reason for the decrease in production: The gaps in the sieve strips are blocked; Uneven feeding. Troubleshooting method: Stop the car and clean the blockages in the gaps of the screen strips; Adjust the feeding mechanism.
4. The reason for the knocking sound generated by the elastic coupling is that the pin shaft is loose; Elastic ring wear; Troubleshooting: Stop the vehicle and tighten the hinge nut; Replace the elastic ring.
5. Causes of knocking sound inside the machine: Non broken objects entering the machine; The fasteners of the lining plate are loose, and the hammer hits the lining plate; Hammer or other parts broken. Troubleshooting: Stop the vehicle and clean the crushing chamber; Check the fastening of the lining plate and the gap between the hammer and the screen strip; Replace broken parts.
6. Machine vibration reason: JawCrusher, commonly known as JawCrusher, is a crusher that simulates the movement of animals’ two jaws and completes material crushing operations when replacing the hammer head or due to wear and tear of the cone head. It is composed of two jaw plates, a moving jaw and a stationary jaw, forming a crushing chamber.
Widely used for medium particle crushing of various ores and bulk materials in industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical engineering.
