Atlas Copco showcased its new line of Powercrusher track-mounted mobile crushers and screeners, including jaw crushers, impact crushers, and cone crushers with a crushing capacity from 242 to 606 tons per hour, and screeners with a capacity of 242 to 485 tons per hour. The four jaw crushers incorporate “Quattro Movement” made possible by an up-thrust toggle plate position. This causes a figure-eight motion in the moving jaw, which increases the feeding capacity and produces a 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 a minimal percentage of oversized material and high reduction ratios and throughputs. The PC 1000 cone crusher is designed to accept an “all-in” feed that increases particle-on-particle crushing, which improves the quality of the end material shape, decreases wear, and may eliminate the need for pre-screening.
