Cover rotating drum grinding machine

摘要

A covered rotating drum grinding machine having a frame, engine assembly and hammermill assembly mounted to the frame is provided. Sitting atop of the hammermill assembly is a rotating drum assembly, which is used to agitate and feed material to be ground into the hammermill assembly. A stationary drum assembly, including an infeed opening through which material to be ground is passed, is provided atop the rotating drum assembly to prevent material impacting the hammermill or other grinding device from being propelled out of the enclosed drum space on a ballistic trajectory.
