Pressure Sifter Removes Oversized Particles

Sealed system can be employed to operate under a blanket of an inert gas.

Kason has introduced its new Vibroscreen, a low-profile pressure sifter designed to remove oversized particles at ultra-high rates. The sealed system can be employed to operate under a blanket of an inert gas, to prevent the escape of hazardous gases and/or to sift in-line with pressurized reactors. It is offered in stainless steel and carbon steel in diameters from 18 to 84 inches (460 to 2,135 mm).

Capable of scalping bulk materials at rates to 50 tons per hour, the 72-inch (183 cm) diameter unit is engineered and constructed to operate under pressure on a batch or continuous basis. Connections to the incoming line, discharge line for on-size particles, and discharge spout for oversize particles are sealed using flexible pressure sleeve connectors.

The Vibroscreen’s "Flo-Thru" design employs two unbalanced-weight gyratory motors mounted on opposing exterior sidewalls of the unit. It also aligns the top inlet above the bottom outlet, allowing on-size material to descend through the screen in a straight-through path at high rates. Oversized material is ejected through a spout at the periphery of the screen.
