Abstract

The invention relates to an eccentric ring hammer coal crusher in coal crushing equipment. The crusher comprises an enclosure, a feeding hole formed at the upper part of the enclosure, a rotor in the enclosure, a rotor counterattack plate, a screening device, a discharge hole formed at the lower part of the shell, a reclamation hole and a power device on the lateral surface of the enclosure, wherein the rotating shaft of the rotor is arranged on the enclosure; the rotor and the screening device form a crushing cavity; the rotor comprises a bracket seat arranged on the rotating shaft and a ring hammer eccentrically arranged on the bracket seat; and the installation center and the geometric center of the ring hammer form an eccentric distance. The ring hammer is eccentrically arranged, once metal impurities such as iron blocks or other hard impurities are mixed into the coal, the ring hammer eccentrically arranged on the bracket seat applies a striking force to the impurities and then rotates in the striking counterforce normal direction, so that destructive damage of the screening device formed by the ring hammer and a tooth stick is avoided, and the service life of the coal crusher is protected and prolonged.

Description

technical field [0001] The invention relates to a ring hammer coal crusher, in particular to an eccentric ring hammer coal crusher. Background technique [0002] A kind of ring hammer coal crusher produced in our country now, including organic body, rotor, mechanical cleaning device, screening device, mechanical screen ring adjustment mechanism, coarse and fine material crushing device, driving motor and other parts. Among them, the rotor part is composed of main shaft, gear ring hammer, ring hammer, etc.; the screening device is composed of multi-stage sieve ring, sieve ring shaft, sieve ring external adjustment joint, sieve frame, etc.; sieve ring shaft and rotor form a crushing chamber. . Coal material crushing is divided into two processes. The first is that the coal material enters the crushing chamber from the feed port. First, most of the coal material is crushed by the high-speed impact of high-rotation multi-row staggered ring hammers; the second is to obtain a sma...
