Abstract
The utility model relates to coal crushing equipment, in particular to an eccentric ring hammer coal crusher, which comprises a casing, a feed port arranged at the upper part of the casing, a rotor, a rotor reverse hammering plate and a screening device arranged inside the casing, a discharge port and a recovery port arranged at the lower part of the casing, and a power device arranged on the side surface of the casing. The rotating shaft of the rotor is mounted on the casing, and the rotor and the screening device form a crushing chamber. The rotor comprises a bracket base mounted on the rotating shaft and a ring hammer eccentrically mounted on the bracket base, wherein the mounting center and the geometrical center of the ring hammer form the eccentric arm. In case that iron blocks and other metal block impurities or other hard impurities are blended in coal, the ring hammer eccentrically mounted on the bracket base applies an impact force on the impurities and then rotates toward the normal direction of the counter impact force, so as to avoid destructive damage of the ring hammer and the screening device formed by toothed rollers, protect the coal crusher and prolong the service life of the coal crusher.
