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.

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.

The gravel screen is mainly used for classification of quarry stone with different sizes, separation of soil from stone, coarse coal and coal powder separation in coal industry, and bulk and powdery material separation in chemical industry.

Aggregate consists of manufactured crushed stone and sand created by crushing bedrock, and naturally occurring unconsolidated sand and gravel. The infrastructure created using aggregate is a major contributor to our current standard of living. Maintaining our lifestyle, passing that lifestyle on to our progeny, and supporting others to achieve developed nation status, will require huge amounts of aggregate. This chapter describes the aggregate industry and sustainable aggregate resource management, including the complex environmental, societal, and social issues associated with the exploration, mining, processing, transportation, and recycling of aggregate resources, and the reclamation of mined-out aggregate deposits.
