Proven to Remove Up to 85% of Fluid

Dewater Swarf & Filter Cake

Disposing 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.

Dewater Swarf & Filter Cake

How it Works

Material is fed into an opening on top of the press (in-feed hopper), 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 wedge wire screen where it is collected for safe disposal.

Material then presses against the end plate (or pressure plate), forcing the end plate to open and allow the de-watered material to discharge. The resistance of the end plate can be adjusted as required.
