Rotary Screen

Usage and Application

Cement,Concrete, River Sand Rotary Trommel Vibrating Screen Machinery used to separate materials by size, for example, separating the biodegradable fraction of mixed municipal waste or separating different sizes of mulch or crushed stone.  Production rates can be vary from 20 to 30 yards an hour to several hundred yards of material an hour based on number of factors described in this article.

Working Principle

The trommel screen is generally 1~4 decks. During running, the drum screen rotating slowly and uniformly, little impacting and vibrating, operating steady. Trommel revolving separator can be used for medium & small material separating.

Feeding into the drum, material 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.
