Magnetoelastic impact ore crusher

Abstract

The invention discloses a magnetoelastic impact ore crusher which comprises a rack body, a rotor mechanism, a plate hammer, a curtain chain, lining plates, a front impact plate, belleville springs, aback impact plate and a magnetic spring assembly, wherein a feed inlet is formed in the upper right end of the rack body, and the curtain chain is arranged at the feed inlet; the lining plates are arranged on two inner walls of the rack body; the rotor mechanism is located in an inner cavity of the rack body and the plate hammer is arranged on the rotor mechanism; the front impact plate and the back impact plate are separately mounted on the upper and back parts of the inner cavity of the rack body; the belleville spring is arranged on a screw corresponding to the front impact plate, and a magnetic spring assembly is arranged on the screw corresponding to the back impact plate; and the belleville spring and the magnetic spring assembly are located on the outer side face of the rack body. By arranging the magnetic spring assembly on the screw corresponding to the back impact plate, the magnetic spring assembly can generate necessary elasticity, so that the position of the back impact plate in the operating process is not fixed, and the crusher is prevented from being blocked by ores on the premise of not affecting the crushing performance.

Description

technical field [0001] The invention relates to the field of ore crushing, in particular to a magnetoelastic impact ore crusher. Background technique [0002] Ore crushers can be widely used in many sectors such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The ore crusher is composed of a casing, a rotor, a striking plate, a hammer head, a bracket, and a lining plate. [0003] The existing crusher casing is composed of the upper body, the rear upper cover, the left side wall and the right side wall. All parts are connected into one body with bolts. Can be replaced, dust leakage between the casing and the shaft is very serious, in order to prevent dust leakage, a shaft seal is provided. The lower part of the casing is directly placed on the concrete foundation and fixed with anchor bolts. In order to facilitate maintenance, adjustment and replacement of grating bars, there is an inspection hole on the front and rear s...
