crush-stedman-300The Grand Slam Series of horizontal shaft impactors from Stedman uses high-chrome metallurgy to increase the wear life of machine components, reducing metal replacement costs. The series consists of 11 high-production models, with capacities ranging from 1,200 to 1,600 tph. The impactor design incorporates both primary and secondary aprons for maximum product control, eliminating the need for grate bars and discharge screens. The impactors’ two-stage crushing action produces more product on the first pass with reductions ratios up to 30:1, even while handling large and slabby feed material. A full-length rotor shaft with two, double-row spherical-type bearing assemblies features a taper lock design to strengthen the rotor for highest reliability.
