Rock Crushers


Atlas Copco’s new Powercrusher line includes 11­ different models of rock crushers and six screener models. The product range covers impact crushers, cone crushers and jaw crushers with a crushing capacity from 242 to 606 tph and includes screeners with a capacity of 242 to 485 tph. The four models of jaw crushers incorporated the unique “Quattro Movement,” which is made possible by an up-thrust toggle plate position. This causes a figure-eight motion in the moving jaw, thus increasing feeding capacity and producing post-crush at the crusher outlet. The six impact crusher models use optimized geometry in the crusher box with hydraulically adjustable swing beams, resulting in minimal percentage of oversized material, and high reduction rations and throughputs. The Atlas Copco PC 1000 cone crusher features cones that are compact units designed to accept an “all-in” infeed, thus increasing the particle-on-particle crushing, which in turn increases the quality of the end material shape and can eliminate the need for pre-screening.
