PRAB - Horizontal Screw Press

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.

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.

PRAB’s Horizontal Screw Press allows fluids to be efficiently separated from metal solids. The press extracts up to 80% of the liquid content, which allows the costs associated in the handling and disposal of these hazardous materials to be drastically reduced. With the addition of PRABMonlan filteration system, these fluids can be recycled back into your process. A PRAB Dualpak briquetter can further enhance the process by increasing fluid recovery up to 99% and yields solid metal briquettes.

The PRAB SP-Series Horizontal Screw Press uses a progressively reduced-pitch screw design to “dewater” wet metal fines. The heavy-duty stainless steel screw compresses the wet material forcing liquids through the stainless steel wedgewire screen. Perforated (2,4 mm) screens with replaceable liners are also available. Variable frequency drives and Class II gearboxes are standard.
