Schenck Process SLV Dewatering Screens are High Frequency machines powered by dual out of balance motors to give linear vibrating motion. They have an inclined back plate fitted with screen panels and a negatively inclined (uphill) screen deck. The inclined back plate is at 45 degrees and is used to rapidly remove significant amounts of the feed water. The bed of solids forms on the screen deck and water percolates through the bed of fines. The bed of fines is compacted during vibration and squeezes the water from the bed as it is conveyed up the deck.

The screen body is a welded-bolted construction with huck bolted joints for structural components and high strength bolts used for replaceable items. The drive beam is a welded construction stress relieved prior to machining. The beam flanges and motor mounting pads are machined ensuring good connection to the side plates and the motor bases.

The screen frame is a welded bolted construction with RHS cross members with cleats to fasten the longitudinals for the mounting of screen surfaces. The screen cross members are Huck-bolted to the side plates.

Standard designs include modular polyurethane or wedge wire screen surfaces.

The out of balance motors have adjustable counterweights to set the vibrating stroke length for the application requirements. These motors are 4 pole speeds as High Frequency are generally considered to give the best results in dewatering applications. These motor drives are simple as there are no vee-belts, geared mechanisms, cardan shafts or guards resulting in minimal maintenance. The motors easily fitted and removed and maintenance can be carried out in a workshop environment.

The screens are mounted on coil springs to isolate approximately 94-96% of the vibrating forces from the support structure.

The screens are protected by a 250 micron thick epoxy paint system following abrasive blast preparation in accordance with Schenck Process Australia’s System S1. Alternate systems are available on request or to suit your particular environment.
