Additional features include a sliding UHMW cover on top of the housing. The mill drive is an SEW hollow bore, 20 HP TEFC motor rated for 230/460 volt, 3-phase, 60 Hz operation, providing a nominal cylinder speed of 24 RPM. The system is supported by two welded A" frame stands with box-style extensions for added height, constructed of carbon steel and coated with Sherwin-Williams Tile Clad epoxy.
