MSS scalping screens are built with a rugged, heavy-duty design for large feed and tonnages. These screens are most commonly utilized in conjunction with an apron, pan or push feeder ahead of the primary crusher. They have a single grizzly or plate type of scalping deck with the option of a second deck with woven wire. MSS screens immediately after a primary feeder gives more effective scalping than a primary feeder with a built-in grizzly. The stroke and speed of the screen remains constant while the feed rate is adjusted by varying the feeder speed providing efficient separation at all times.

MSS Scalping screens are often utilized when excessive clay or an abundance of fines are present, making them capable of efficient
scalping in the most difficult applications. Typical feed material is blasted rock, ripped rock or gravel with high fines content, often containing difficult wet natural fines or clay. The MSS Screens are able to maximize the efficiency of the primary plant across wide variations in application.

•    Maximum efficiency
High G force resulting in very high scalping efficiency for better feed to the crusher

•    Speed and stroke is adjustable
•    Long stroke capability: better scalping efficiency (when feed material contains high ratio of flaky material)
•    Shape of Scalping grizzlies result in: reduced blinding when feed is sticky and contains fines (increased capacity)

•    High-Quality Vibrators require very little maintenance
•    Heat Treated and Machined Vibrator Bridge Increases Lifetime
•    Adjustable Grizzly Bar Spacing allows to adapt the feeder to quarry
•    By-Pass Chute Allows to divert material away from plant.
