The Scalper 77C Double Deck Screening Plant is a patented, heavy-duty portable screener capable of screening soils, aggregates and more. It works best when paired with your 2 yard (1.8m) front end loader. A large feed opening directing material on the 7'-0" (2.1m) long shaker screen is standard equipment in this easy-to-use and easy-to-own Scalper 77C. The pile heights created by the fines discharge conveyor will give the operator hours of uninterrupted processing time. A compact high capacity processing plant for nearly any feed material.
