International Classification:
B02C 13/28
US Classification:
241194, 241197, 241300
Abstract:
The invention provides a particulate size reduction system including a grinding chamber, a center shaft defining an axis of rotation and configured for rotational motion within the grinding chamber, a wheel assembly mounted on the center shaft and at least one swing hammer mounted on the wheel assembly. The at least one swing hammer preferably includes a base portion having a first end having a mounting portion for attachment to a wheel assembly of a material treatment system, a second end, an inboard portion proximate the mounting and an outboard portion proximate the second end. The swing hammer also preferably includes a wear pad disposed on the base portion. The wear pad preferably substantially covers a face of the base portion. The wear pad preferably extends from a point proximate the second end of the base portion toward the first end of the base portion to a location proximate the mount.
