ABSTRACT:
This relates to a device for crushing sand lumps. The device includes a tub which is resiliently mounted and is provided with means for vibrating the same in a generally vertical direction parallel to a rear wall of the tub. The tub rear wall is hollow and is provided on the inner face with perforated crusher plates. Sand flow through the crusher plates is down through the hollow rear wall and there is an upwardly directed airwash for the falling sand. The lower portion of the rear wall is in the form of a door mounted for swinging movement about a horizontal axis. The door is operated by a cylinder having an axis parallel to the direction of vibration and the door is opened during the vibration of the tub so as to direct scrap and uncrushed lumps out through the lower portion of the rear wall in the same direction of salvaged sand flow. The crusher plates include a main wall having elongated slots forming the perforations and there are lugs projecting forwardly from the main wall above and below the slots with the vertical dimensions of the lugs and slots and the spacing thereof being in accordance with the amplitude of intended vibration to provide a maximum crushing effect.
