ABSTRACT:
An impeller assembly having a hard wear plate has replaceable impeller shoes and is rotated on a vertical axis to throw material against vertically reciprocated, replaceable breaker bars to crush the material. The breaker bars are reciprocated by power driven jacks. The material is supplied to the impeller through a spout having a dust-sealing valve. The impeller has a shaft journalled in a sealed impeller shaft housing mounted resiliently on a base, and the shaft is driven by a double universal joint drive. Lubricant is pumped from a sealed input shaft housing into the impeller shaft housing and back to the input shaft housing.
