Crushing device with a preadjustable container volume

摘要

The work chamber can be made smaller by the piston moving over the base of the container. The piston has an inherent weight causing continuously to sink into the work chamber (25) of the container (10) in the direction of the base-positioned blade (15). The piston by means of securing formations (18,19) on its outer cover surface can be fixed in a predetermined end position.
