Factory Supplier Wear Resistant Crushing Shaft Group For Coal Mine Crusher

Product Details

The operation effect of the crushing shaft group of the crusher directly affects the crushing capacity of the crusher and the production efficiency and economic benefit of the coal mine. Understanding the structural characteristics of the crushing shaft set of the crusher is conducive to reducing the failure rate of the scraper conveyor and improving its reliability.

structure

The crushing shaft is mainly composed of spindle, hammer body, hammer head, bearing seat, bearing, seal and other accessories.
