The Williams Traveling Breaker Plate Mill is a non-clog hammer mill designed to permit a Slugger Crusher to reduce muddy rock, clay, shale, or bauxite to 3/4" or smaller. As a non-clog hammer mill, the Traveling Breaker Plate Mill, or TBP Mill, can reduce wet, sticky material such as clay or bauxite to a size suitable for further refining without clogging.
