Cone crusher's wearing parts including frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, cone crusher concave, springs and hydraulic pressure station for adjusting discharge opening. 

When used in a cone crusher, the bearings may be burned if not handled properly,Generally speaking, the burned parts of the bearing are all about the distance from the upper end of the bearing. The burned out length is smaller, and the inner diameter of the burned out part is smaller than that before the burning out. Such operating records indicate that most of these accidents occurred after heavy trucks were running after replacing the new bearings.

Before the machine burned out, about no-load operation was performed. After everything was running at normal full load, the motor current began to appear abnormal, which was higher than normal. The amount did not decrease, the fuel supply pressure of the thin oil station decreased, and the current increased sharply. During the inspection of the shutdown, it was found that the bearing had been burned.

The cause of the bearing burnout may be that the thin oil station cannot supply oil properly; the gap between the bush and the empty eccentric shaft is less than the technical requirements and the quality of the bushing is unqualified or the quality of the lubricant is unqualified. The normal use of the machine, it is necessary to operate correctly
