Rotary Screen also called Drum Sieve,rotary drum screen, roller screen and Trommel screen, it is uesd for the classification of powder materials and sieve effect is good ,60-200 project screen. Power 0.75-3KW, output :500-1500KG / hour.
Features of Drum Sieve:1, the installation angle is small, easy to plug;2, small footprint;3, low noise and dust pollution;4, smooth;5, screening efficiency is high;6, large output;7, easy process layout.

Application of Rotary Screen
Material feeds into the drum, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum. 



Advantages of Rotary Screen 
* Configured for economical & efficient classification, Screening and grading
* Heavy duty trommel drum with lifters at the front to facilitate material break up
* Screen replaceable for different mesh sizes
* Multiple screen size
* Easily changed screen plates
* Largest processing capacity in the industry
* Unique screen design, result in higher capacities, longer screen life and no material clogging
* Heavy duty feed hopper and extension
* Discharge chute
* Gear drive mechanism
* Variable speed drive mechanism
 
Working Principle of Rotary Screen: 
The Trommel screens provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. This method of screening helps to reduce operating and investment cost and to increase product quality, while allowing rapid and large volume processing. Our Trommel screens are constructed of high quality material, designed for high performance, high production rates, lower operating costs and lower maintenance. This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal Concentrator, spirals, jigs etc.
