Using three thumb screws, the unit's end plate, cylindrical screen and shaft-mounted paddle assembly can be removed in less than one minute, providing access to clean all material contact surfaces.

As material is gravity-fed into the unit, rotating helical paddles accelerate the movement of particles against the cylindrical screen and through its apertures. On-size material then drops through the first of two discharge spouts, into processing equipment or a storage vessel. The paddles, which do not contact the screen, also serve to break-up agglomerated materials. Oversized particles unable to pass through the apertures exit through the end of the screen cylinder and fall through a second discharge spout for discarding or re-processing.

Cylindrical screens are offered in woven nylon, monofilament, stainless steel, and stainless steel wedge wire to accommodate a wide range of materials.

The unit is constructed of stainless steel with all continuous welds ground and polished to industrial, food, dairy or pharmaceutical standards.

The company also manufactures high-capacity centrifugal screeners, circular vibratory screeners, and circular fluid bed dryers and coolers.
