Impactor line hits 'Grand Slam'

摘要

The Grand Slam Series of horizontal shaft impactors from Aurora, Ind.-based Stedman uses high-chrome metallurgy to significantly increase the wear life of machine components, reducing metal replacement costs. Tackling a variety of applications from limestone, gravel and asphalt materials, Grand Slam impactors reduce material size more efficiently with maximum up time. The Grand Slam Series consists of 11 high-production models, with capacities ranging from 5 tph to 1,200 tph. The impactor design incorporates both primary and secondary aprons for maximum product control, eliminating the need for high-maintenance grate bars and discharge screens that often clog. 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 reliability. The rotor features either a two-, three- or four-row breaker bar design, depending on machine model size.
