The OreMax is available as a fully-autogenous, semi-autogenous or anvil type crusher. The anvil type units are designated as OreMax - ST/AR machines. The OreMax Pre-mill units are designed for extra-fine crushing and grinding.

Maximum recommended feed size will vary dependent on type, hardness and shape of rock or ore to be crushed. Typically, maximum feed size is limited to 4 (100 mm) depending on size of the machine, connected drive power and reduction ratio. REMco OreMax units can be used as pre-milling machines before ball mills to eliminate rod mills. Another use for OreMax units is to relieve the crushing load of overworked older cone crushers and produce a finer product for the grinding stages in metal mining and cement operations.
