A crusher is a machine designed to reduce large solid chunks of raw material into smaller chunks. Crushers are commonly classified by the degree to which they fragment not starting material with wares crushers not reducing it by much, intermediate cruiser fragmenting it much more significantly and grinders reducing it to a fine power.
55 The invention relates to a roll-crusher, wherein a roll is provid-ed with rings of teeth spaced axially from each other and designed to move with a shearing action be-tween the teeth of a grating, partly surrounding the roll on its underside and to one side the grating being adapted to be swung out of the range of the roll teeth. Crushers of this kind are used for crushing scrap material.
Mode of Operation. Comminution of the feed material between the two rolls (fixed and moveable) by mechanical pressure up to 200 to 400 kN, hydraulically induced. Opening of the gap between the crushing rolls in case of overload (e.g. caused by an unbreakable foreign object) within milliseconds to let that piece pass thus avoiding a shut-down.
