RockMax crushers can be operated in either open or closed-circuit. Closed-circuit operation is recommended in order to achieve the lowest net operating cost, best particle shape, and the highest production. RockMax crushers are intended for producing crushed products between 1 1/2” to 3/8” / 40mm to 10mm.

The crusher operates by accelerating the material to be crushed via a high energy (patented) rotor, into a crushing chamber lined with the same material. This gives the rock on rock (autogenous) crushing action. Where a product size is required below that of the feed size, it is usual to operate the crusher in closed circuit, with
