ABSTRACT:
Crushing apparatus having oppositely disposed endless loops of crushing belts disposed so that inner runs of the belts are spaced closely adjacent to each other to define throat therebetween. Each belt has a slat bed of closely spaced slats connected together and extending transversely thereacross to provide a flat, essentially continuous surface when the slats are coplanar. Belts are powered, and converging intake means admit material to be crushed between the belts. Roller means are journalled on the slats, and rail means extending adjacent and along the two opposed inner runs of the belts cooperate with the roller means to support the inner runs of the belts against crushing forces.
