Cone crusher with bottom spring adjustment type mechanism

Abstract

A cone crusher with a bottom spring adjustment type mechanism is provided. The cone crusher includes a bottom frame, an upper frame, an eccentric mechanism arranged on the bottom frame, a main shaft arranged on the eccentric mechanism, a movable cone fixed on the main shaft above the eccentric mechanism, and a fixed cone arranged in the upper frame. A discharge port is formed between the fixed cone and the movable cone. A bottom spring mechanism is arranged in or connected to the bottom frame. An upper end of the bottom spring mechanism elastically supports the main shaft through a thrust bearing unit. By using the bottom spring mechanism to elastically support the main shaft, the solution has the advantages of simple structure, low costs, and convenient maintenance. Furthermore, a problem of wear of a sealing member due to the use of a hydraulic cylinder technology is avoided.
