The frequent iron crushing of the cone crusher will not only harm the equipment, but also waste time and economic costs due to shutdown and maintenance, delay the production process, and affect the economic efficiency of the enterprise. This article shares with you the harm caused by frequent iron crossing to the cone crusher.

1.The parameters of the crusher are abnormal after entering the iron
When the cone crusher enters the iron, the iron is hard and cannot be broken, and it is stuck between the moving and fixed cone liners. At the moment of trying to break, the pressure rises instantly, the power also increases, and the oil temperature rises; After the crusher detects that iron parts enter the crusher, the crusher will reduce the pressure and the main shaft, increase the ore discharge port, and perform iron discharge to prevent the damage of the crusher from expanding, but the damage to the crusher in the process Very big.

2, causing site damage
When iron parts enter the crushing cavity, the hydraulic oil pressure that lifts the main shaft rises momentarily and then decreases, and the main shaft tilts while descending, resulting in high temperature burns on the bearings.

3. Make wear parts excessively worn
When the iron pieces enter the crushing cavity, if the size of the iron pieces is larger than the crusher discharge port, they will be stuck between the moving and fixed cone liners. The entering iron parts will cause the rigid cones to collide with the fixed cone liners. Causes the lining board to loosen or crack, causing excessive wear of moving parts, fixed cone lining boards and boom bushings, which seriously affects the normal use cycle of the wear parts, and at the same time, tears the boom oil seal during the spindle drop Causes leakage of grease.

4.The main shaft breaks and the frame cracks due to frequent iron crossing for a long time.
When the crushing cavity enters the iron parts, the impact causes uneven force and hydraulic oil pressure changes on the lower frame and the main shaft. Frequent iron crossing causes fatigue of the frame and the main shaft, and then cracks occur in the lower oil return tank. , Need to return to the factory for repair, repeated repairs lead to failure and scrap, causing the spindle to break scrap.
