Abstract
Abstract A beverage container crusher adapted to receive for crushing beverage containers holding liquids, the beverage container crusher having an upper feed hopper to receive a plurality of beverage containers, the beverage containers directed to a pair of synchronized, counter-rotating crushing drums. The crushing drums are designed such to initially pierce the beverage container to permit the ready escape of the contained liquids as the beverage container is being crushed between pyramidal shaped crushing teeth, the piercing being accomplished by pyramidal shaped piercing teeth situated on the primary crushing teeth, the primary crushing teeth attached to the crushing drums. A motor and speed reducer drives one of the crusher drums which in turn through a connecting gear, drives the other crushing drums through its connecting gear. The beverage containers are first pierced to relieve the contained liquid and then crushed between the crushing teeth to flatten the containers. Immediately below the crushing drums is a wire mesh basket which receives the crushed containers, the liquid formerly held in the container also passing into the wire mesh basket but escaping through the wire mesh to a collection sump pan immediately below where it is collected and drained off.
