Specifications

 Working principle of coal screen:

 The rotary drum device is connected with the motor by shaft coupling through motor reducer, and is driven by the motor to rotate around the axis shaft line. When the materials flow into the rotary drum device, as a result of the inclination and rotation of the rotary drum device, the materials on the screen surface will rotate and roll, finally the qualified materials (undersize materials) will be discharged through the screen mesh which is installed around the excircle of the rotary drum, and the unqualified materials (oversize materials) will be discharged from the end of the rotary drum. The materials rotate and roll in the rotary drum, so the materials stuck in screen pores can be ejected out to prevent the screen pores from being blocked

 Application of coal screen:

 1.Quarry: suitable for screening and classifying gravel, clay, mountain meal, sand, etc.

 2.Coal Industry: suitable for screening and classifying lump coal, coal dust, coal washing, etc.

 3.Chemical,Mineral selecting Industry: suitable for grading and classifying lump, powder substance.

 4.Metallurgy, construction and other industries
