Introduction Of Scraper Conveyor

Scraper conveyor, aka scraper chain conveyor, is through traction of scraper chain to convey bulk material in the tank. Scraper conveyor is an important transportation equipment for materials transporting in coal mine, chemical mines, metal mines and power stations. It is composed of the central tank, chain, scraper and traction system, among them, the central tank is the main part of the scraper conveyor, steel central tank has been nearly a hundred years of history. There are several possible disadvantages in the long-term using process:

Working Principle Of Scraper Conveyor

Scraper Conveyor

The chute recipient of coal, waste rock, fix the scraper on the chain as a towing component. Drive the sprocket on the head shaft to rotate after the start of machine head transmission, let scraper chain cycle operation led material move along the chute, until the machine head unloading.
