Abstract
A scrap metal crusher includes a tapered chamber having a relatively large inlet at one end and a relatively small outlet at the opposite end of the chamber. A rotary crusher arm is axially mounted for rotation in the tapered chamber. A plurality of vanes are disposed along the inner surface of the tapered chamber, which vanes in cooperation with the rotary crusher arm convey scrap inserted into the inlet of the tapered chamber toward the outlet of the chamber while simultaneously crushing the scrap. A throat disposed adjacent the outlet of the chamber allows passage of crushed scrap therethrough to a discharge chute. The throat is automatically enlarged upon jamming of the crusher to permit any material causing the jamming to pass through the throat to the discharge chute.
