The stainless steel unit, Model 24-RDS-24, is comprised of a 24 in. (61 cm) diameter x 24 in. (61 cm) long rotating cylinder with durable 0.08 in. (2 mm) wedge-wire screening, a variable speed drive, head box, discharge chute and support structure, reducing floor space and headroom requirements compared with non-rotating equipment of equivalent capacity.
Solids-laden effluent discharges from the head box and overflows a weir, flooding the entire length of the variable speed, rotating wedge-wire drum screen. Solids deposited on the screen gravity-drain through slotted apertures to moisture levels in the 20 percent range before being removed by a doctor blade and discharged through a chute.
Liquid passing through the screen falls onto an internal baffle that concentrates the flow, forming a full-length water knife that impinges against the underside of the screen, dislodging any solids blinding the screen. An optional clean-out spray line removes exceptionally oily, greasy, fibrous or resinous matter trapped in screen apertures.
Powered by a Âľ HP (0.55 kW) wash-down duty motor, a variable-speed drive allows adjustment of drum rotation speed to achieve maximum dewatering effectiveness.
The wedge-wire screen of the cylinder is also available in apertures from .010 to .100 in. (50 micron to 2.50 mm).
The rotating drum is the only moving part contacting material, minimizing initial cost, operating cost and maintenance.
Models with drums 24 in. (61 cm) in diameter are offered in lengths of 24, 36, 48, 60, and 72 in. (61, 91, 122, 127, and 183 cm).  Models with drums 36 in. (91 cm) in diameter are offered in lengths of 96 and 120 in. (244 and 305 cm) and separate solids at rates to 4,650 gal/min (17,600 liters/min.)
Typical applications include: separation of various solids and sludges from municipal and industrial wastewater, food processes, pulp and paper production and rendering processes; removal of extruded pellets from cooling baths; and separation of debris from any variety of plant and equipment cleaning processes.
In addition to liquid/solid separation equipment, the company manufactures size reduction equipment including Pin Mills, Attrition Mills, Lump Breakers, Screen Classifying Cutters, Rotary Knife Cutters, Hammer Mills and Shredders. Mixing and blending equipment includes Rotary Batch Mixers, Continuous Rotary Blenders, Vee-Cone Blenders, Ribbon/Paddle/Plow Blenders, Fluidized Bed Mixers and Variable Intensity Blenders.
