An Overview of Rotary Screen

Rotary screen is mainly composed of the motor, reducer, roller device, airtight cover, feed port and discharge port for screening materials. 

Rotary screen is mainly used for sieving big or small stones, separating soil and gravel, coal blocks and coal powder, etc. It can also be called gravel screen or stone separator. Since roller device is composed of filter screen, it is also called rotary sieve.

Working Principle of Rotary Screen

Roller device is tiltly installed on the frame. Firstly, motor is connected with speed reducer, which joins the roller device through the coupling, and roller device is driven around its axis. When the material enters into the roller device, material on the screen surface flips and rolls due to the inclination and rotation of roller device. Qualified material will be discharged from the bottom of roller drum while unqualified material will be discharged from the rear of the discharge port.
