A trommel screen, also known as a rotary screen is an essential unit when there is need for physical size separation.
Physical size separation is achieved as the feed material spirals down the rotating drum . The material smaller than the screen apertures passes through the screen for further processing.
When designing a Rotary screen, the main factors affecting the screening efficiency and production rate are the rotational velocity of the drum, mass flow rate of feed particles, size of the drum and inclination of the screen. To achieve the desired application of the screen, a balance has to be made between the screening efficiency and production rate.
The trommel may have multiple sized apertures down it’s length to separate into numerous size fractions.
