Ore from the primary crusher will be scrubbed ahead of secondary and tertiary crushing to remove clay associated with the ore. The scrubber will be equipped with a trommel screen and oversize material from this screen will be crushed using an open circuit secondary impact crusher while trommel undersize will be wet screened on a double deck screen.

2. Build the crusher. The basic structure of the crusher is a length of 2×4 wood. At one end, the actuator is anchored using the fixtures supplied with it. The actuator’s shaft is then fixed to a block of wood that crushes cans against an end stop. Two plywood sides help prevent the can escaping while it’s being crushed.

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
