The scraper conveyor consists of a central trough, a chain, a scraper and a traction system. The scraper is fixed on the chain to form a scraper chain as the traction component. It can transport materials upward or downward, but the upward transportation generally does not exceed 35 degrees, and the downward transportation generally does not exceed 25 degrees. In fact, it is preferably no more than 20 degrees.
scraper conveyor is also widely used in metallurgy, building materials, electric power, chemical industry, cement, ports, docks, coal, mining, grain and oil, food, feed and other industries and departments. It is a very simple and effective equipment.
