OHT coarse scalper screens
OHT vibrating coarse scalper screens are rugged screens with circular oscillation. They are used for primary screening of run-of-mine material, aggregate and to separate clay from material before primary crushing.
OHT coarse scalper screens are designed with two decks, where the upper deck is either a grate deck or has holes and guiding bars, and the lower deck is a wired or finger deck. The structure is lighter than that of HT coarse screens.
