Roller presses

    Go back to markets

    In order to crush ore, roller presses, or high-pressure grinding rolls (HPGR), utilize two counter-rotating rolls – one fixed and one movable. Compared to traditional systems, this design increases stability and efficiency. Roller presses can be used for grinding as well as compacting. The drive power is transferred to the grinding rollers via multistage Brevini® planetary gearboxes mounted on the drive end of the roller shaft using shrink disc coupling or a low-speed flange. Traditional drives above 400 kW are equipped with fluid- or torque-limiter coupling and a cardan shaft. Bulk material is fed through the gap between two rollers, then through a feeding device on top of the machine, which can vary depending on feeding method.
