Drum screen is made of mainly motor, reducer, rolling cylinder device, frame, cover gasket, feed inlet and outlet. Roller device tilt installed on the rack. Motor through the reducer connects with roller device through shaft coupling, drive roller device turns around its axis of rotation. When the materials enter the cylinder device, due to tilt and turn of the drum unit, which makes the material on the surface of the screen to flip and roll, the qualified materials (undersize) expels from the outlet at the bottom of roller, unqualified materials (oversize) expels from the discharge gate at the end of the cylinder. Due to the materials flip and roll inside the drum, the card in the mesh material can be popped out,preventing the mesh plugged. The principle and structure of drum  screen sand, drum screen separated machine,and the drum screen are almost same, which is difference between people's cognition  and given name of it.

The adaptation scope of drum screen

    Stones in the quarry for size grading. And isolated mud and stone powder.

Quarry and sand separation is used

    The coal industry used to separate lump coal and pulverized coal and coal washing (part of coal washing machinery) The chemical industry, mineral processing industry for size block classification and separation of powder material. Performances and  characteristics of product

    Screen doesn't plug holes

    Simple structure, smooth operation, low noise

    Less investment, high reliability, convenient maintenance, long service life

    For different materials used in various of wear-resistant mesh (screen material can chose manganese steel wire, stainless steel, etc.) ,high screening efficiency Applied characteristics

High screening efficiency, and can realize material screening between 2-80 mm, at the same time can go on 1-5 class material screening

    Change various sizes of the mesh screen at any time according to the demand of material sieving, multi-usage Small size, low power.
