Horizontal Screw Press

Dewater Swarf & Filter Cake Up to 85%

horizontal screw pressDisposing hazardous grinding swarf or filter cake can be difficult and expensive. PRAB's horizontal screw press processes material that is 40 to 50% wet with coolant or cutting oils to remove up to 85% of fluid.

Use as a stand-alone unit or in combination with the Dualpak™ briquetter to recover up to 95% of fluids. Recycle fluids with one of PRAB's fluid filtration and recycling units for even greater savings.

How It Works

Material is fed into an opening on top of the press, passing through a variable pitched auger screw and then compressed against the end plate (held in position by an air cylinder). As the material is squeezed, the extracted fluid passes through a perforated screen where it is collected for safe disposal.

Material then presses against the endplate, forcing the endplate to open and allow the dewatered-material to discharge. The resistance of the endplate can be adjusted as required.
