Metal impact sound when jaw crusher is running at high speed
A、The sound of metal hitting in the lower part when idling
<1>, the sound of moving jaw and fixed jaw tooth plate hitting each other is due to the ore discharge opening is too small, it should be adjusted in time.
<2>, the sound of impact in thrust plate support or pad adjusting device is usually caused by the elasticity of tie rod buffer spring disappearing or damaged, or the spring is not pressed tightly, when the elbow plate of movable jaw plate and the body are not combined closely, so that the head of elbow plate and the two ends of the support produce impact, and the adjusting shims hit each other, the compression nut should be tightened in time until the sound of impact disappears.
<3>, it may be caused by serious wear or loosening of elbow plate gasket and serious wear of elbow plate head, which should be replaced in time.
B、Metal crashing sound and shaking of liner plate when working
- the crushing cavity side liner and two jaws fastening screws are loose and broken, timely fastening or replacement.
- the head of the moving jaw body impact sound; the reason is the eccentric shaft bushing wear; eliminate the method, re-scraping research or replace the bushing.
- the jaw plate displacement, the top of the teeth and the top of the teeth relative; should immediately adjust the position of the two tooth plate or replace the jaw plate.
- the gap between the moving jaw and the bearing is too large after wear, so that the bearing outer ring relative rotation; should immediately replace the bearing, moving jaw body, or moving jaw body group.
