The crusher breaks down the rock to a smaller size. The screen is the "cash register" of the crushing circuit in that it determines the final gradation of each product pile. In general, it is good practice to oversize the screen to account for changes in environmental conditions that can affect the overall performance of the crushing circuit.

Mobile plants allow the combination of prescreening – that prepares the rock for the crushing process and grading, which precisely separates defined aggregate particle sizes into different end products – to be integrated with the crushing unit into one single machine. In the first stage, the material is screened using an active prescreen.

First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.

For performance efficiencies, proper circuitry should be designed around the crusher cone, says Schultz. Importantly, the circuit should be engineered to provide the crusher cone with choke-fed material, or enough material to keep the crusher full. Having too little feed can cause the crusher to side load, which stresses components.
