Screen Systems

ROTEX screeners are self-contained production screening machines for separating dry materials according to particle size. Through their unique gyratory motion of near-horizontal screen surface, combined with a positive screen mesh cleaning system, ROTEX provides unusually high efficiency and capacity – all the result of continuing development for hundreds of applications throughout scores of industries.

ROTEX Screeners utilize a unique screening action that provides accuracy of separation at high production rate. As shown in the illustration here, materials enters at top left where it is distributed over the entire width of the screen surface and conveyed towards the discharge end. Large particles remain above the screen surface, while smaller particles pass through, as determined by the screen openings used for each particular application. The model illustrated here is a typical two-surface ROTEX, which separates material into three different grades. This model is widely used in fertilizer industry, especially for urea granulation plants.
