    Introduction of scraper conveyor

    SCRAPER CONVEYOR IS INTRODUCED

    The scraper conveyor is a conveyor that is pulled by a scraper chain and transports bulk materials in the tank. Other names: slipper; electric slipper; scraper conveyor is an important transportation tool for conveying materials such as coal mines, chemical mines, metal mines and power plants. It consists of a central groove, a chain, a scraper and a traction system. Among them, the middle groove is the main part of the scraper conveyor. The steel middle groove has a long history and has the following disadvantages during long-term use:

    Working principle of scraper conveyor

    THE WORKING PRINCIPLE OF SCRAPER CONVEYOR
    Scraper conveyor

    The working principle of the scraper conveyor is to use the open chute as a support for coal, vermiculite or materials, etc., and fix the scraper on the chain (composing the scraper chain) as a traction member. When the machine head transmission is started, the sprocket on the head shaft of the belt machine rotates, so that the scraper chain runs in a circular motion along the chute until the machine head is unloaded. The scraper chain runs around the sprocket for stepless closed loop operation to complete the conveying of materials.
