Beater disintegrating machine

Abstract

The invention discloses a hammer plate type crushing machine, and belongs to the field of a hammer plate type crushing machine. The crushing machine comprises a pressing screen rack, a screen plate, a screen plate rack, a motor, a machine base, a junction box, a rotor, a rotor shaft and hammer plates, wherein the motor arranged on the machine base is connected with the rotor of the crushing machine by the junction box; the rotor, the screen plate and the screen plate rack jointly form a crushing room; the rotor shaft of the rotor is connected with the junction box, and the rotor is provided with a plurality of hammer plates; a big separation sleeve is arranged between two adjacent hammer stand plates of the rotor shaft, the big separation sleeve comprises an inner edge of the separation sleeve and an outer edge of the separation sleeve, both sides of the inner and the outer edges of the separation sleeve are closely and fixedly connected with the adjacent hammer stand plates respectively; the inner edge of the separation sleeve is arranged on the rotor shaft, and the outer edge of the separation sleeve is arranged on the inner side of the mounting position of the hammer plates, and is 1 to 60mm away from the moving track of the hammer plates. Compared with prior art, the crushing machine has the advantages of improving the parts of the rotor-big separation sleeve, enhancing the operational balance of the rotor and lowering the influence on operational balance of the rotor due to wearing of parts.

Description

technical field

[0001] The invention relates to a hammer mill, in particular to the improvement of the sieve plate, the rotor and the crushing chamber of the hammer mill. Background technique

[0002] At present, the large spacer sleeve on the rotor spindle of the hammer mill is a solid circular sleeve, as attached Figure 10 As shown, this large spacer includes a circular spacer body 15-1 and a shaft hole 15-2, the shaft hole 15-2 is set in the center of the spacer body, the thickness of the spacer body is uniform, and the large spacer passes through the shaft hole 15-2. 2 The hammer frame plate installed on the main shaft of the pulverizer rotor to isolate the rotor. Due to the large difference between the outer diameter of the large spacer and the outer diameter of the hammer frame plate, the outer periphery of the hammer frame plate is prone to vibration during the high-speed operation of the rotor, thereby affecting the stability of the rotor operation.
