Crusher size reduction ratio

SBM builds Single Roll Crushers, Double Roll Crushers, Triple Roll Crushers and Quad Roll Crushers, with various models of each design. SBM’s heavy-duty fabricated steel frame design, abrasion-resistant steel plate liners and easy-to-maintain parts mean decades of productive service.

SBM’s roll elements can be designed to meet any application. They are available in a variety of diameters, widths, configurations and surface patterns and can be a solid, cast shell with a through shaft, flanged stub shafts or segmented bolted to hubs or a barrel. Roll and crushing plate tip elements are produced in our foundry and are cast from iron, manganese and alloy steels of up to 500 Brinell hardness. For maximum wear life, SBM provides weld-on carbide teeth and can apply overlay hard facing to any applicable surface.

Driven by electric motors and V-belts, all SBM Roll Crushers have increased efficency, high through-put for increased production and low roll speeds that minimize dust and fines. The low headroom, compact design reduces installation costs. SBM Roll Crushers are designed for safe operation with exposed moving components guarded in accordance with MSHA and OSHA. In case of jamming or plugging of the rolls, underspeed detection de-energizes the electric motor.
