Impactor with third crushing chamber

Stedman says that the Crush Plus Grinding Path System on its Grand Slam secondary horizontal shaft impactor creates a third crushing chamber to maximize one-pass product yield, minimize oversize, improve material soundness, and produce highly cubical product. The impactor series uses high-chrome metallurgy to increase wear life and reduce metal replacement costs.

Multi-cage mill

Stedman’s “H” Series Multi-Cage Mill is available in four sizes up to 250 tons per hour with two-, four-, or six-row design. The company says the mill can crush, grind, pulverize, blend, and mix a variety of materials — wet, sticky, or dry. Air cannons are mounted at the intake and discharge to help prevent wet, sticky material buildup; heaters are installed on the grinder housing to help retard wet material buildup.
