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.
An apparatus for crushing articles, comprising a housing, first stage crushing means disposed within the housing and disposed to receive and crush a plurality of said articles, second stage crushing means located within the housing to receive partially crushed articles from said first stage and to provide a secondary stage of crushing, delivery means for delivering the partially crushed articles from said first stage crushing means to the second stage crushing means, recirculating conduit means for conducting partially crushed articles from a location between said first and second crushing means to a second location upstream of said first crushing means, and means associated with said first crushing means for moving said articles through said recirculation conduit means during periods when said second crushing means cannot accommodate the flow of partially crushed articles.
An apparatus for crushing articles, comprising a housing having an inlet to receive articles to be crushed, feed conveyor means for feeding articles to said inlet, rejection means operably associated with said feed conveyor means for rejecting heavy articles having a weight more than a pre-set value from said conveyor means, first stage crushing means disposed within said housing adjacent said inlet and disposed to receive and crush a plurality of said articles, second stage crushing means located within the housing to receive partially crushed articles from said first stage and to provide a secondary stage of crushing, delivery means for delivering the partially crushed articles from said first stage crushing means to the second stage crushing means, recirculating means for conducting partially crushed articles from a location between said first and second crushing means to a second location upstream of said first crushing means, means associated with said first crushing means for moving said articles through said recirculating conduit means during periods when said second crushing means cannot accommodate the flow of partially crushed articles, and discharge means for receiving the crushed articles from said second stage crushing means and discharging the crushed articles to a collection site.
