ABSTRACT:
An apparatus for crushing articles, such as aluminum beverage cans. The crushing apparatus includes a primary crusher followed by a secondary crusher. The primary crusher is composed of a rotatable, polygonal-shaped drum having a blade mounted on each flat surface which projects outwardly beyond the surface. The articles or cans to be crushed are introduced into the area between the drum and a spring loaded pressure plate, and on rotation of the drum, the blades engage the articles and move them into the nip between the drum and the pressure plate to provide a primary stage of flattening of the cans. The cans are then delivered to the secondary crusher which comprises a pair of cooperating rolls, which more fully crush or flatten the cans and deliver them to a pneumatic discharge conveyor. The apparatus also includes a feed conveyor having a provision for rejecting steel cans, as well as heavy objects, such as cans filled with liquid or foreign materials.
