HARD MATERIAL DECOMPOSITION CRUSHER

WIPO Patent Application WO/2022/120893

A1

A hard material decomposition crusher, comprising a rack, a fixed jaw plate, a movable jaw plate, an eccentric shaft rod, and a flywheel. The flywheel is connected to the eccentric shaft rod. The eccentric shaft rod is also at the same time connected to a movable jaw, and an upper surface of the movable jaw is connected to the movable jaw plate. The fixed jaw plate is fixed onto a surface layer of the rack. Teeth of the fixed jaw plate and teeth of the movable jaw plate are uniformly distributed in arrays on surfaces of the jaw plates in the horizontal direction. The teeth on the movable jaw plate are in one-to-one correspondence with the teeth on the fixed jaw plate. The plane where a lower section of the fixed jaw plate is located is parallel to the plane where a lower section of the movable jaw plate is located. Cross sections of the teeth in the lower sections of the jaw plates are configured as isosceles trapezoids. By observing from a high angle of the crusher, the concave-convex and staggered teeth of the movable jaw plate and the fixed jaw plate form a crushing cavity; by means of the arrangement of the shape of the teeth, the planes where the teeth are located are at oblique angles with the surfaces of the jaw plates, so that materials are in inclined planes during a crushing process; and the process is labor-saving.
