Impact Crusher vs. Cone Crusher - Sepro Aggregates

Cone Crusher Applications. Cone crushers, a type of compression crusher, have less versatility than a horizontal impact crusher, but a great capability to guarantee a finished product size. If set at 2”, typically 80% of the final product will meet the 2” target which is not something that can be replicated by jaw crushers or impact crushers.

Maximizing Your Screening Efficiency Aggregates ...

Screening efficiency measures how much of the desired aggregate is accurately separated during the screening process. For example, if your screens are operating at 80% efficiency, that means 80% of the desired aggregate size passes through the screens while 20% does not. Efficiency should be as close to 100% as possible, but keep in mind that ...
