Wheel tooth type crusher

Abstract

The invention discloses a wheel tooth type crusher which comprises a base, an casing, a main unit, two sets of drive mechanisms and a hydraulic adjustment safety system; wherein the casing is arranged on the upper side of the base; the main unit which comprises a rotor part is arranged in the casing; the two sets of drive mechanisms are arranged by both sides of the main unit; the rotor part consists of a fixed roll shaft, a movable roll shaft, fixed bearings and movable bearings; the fixed roll shaft and the movable roll shaft are arranged in parallel; the fixed bearings and the movable bearings respectively bear the fixed roll shaft and the movable roll shaft; the outer surfaces of the two roll shafts are respectively provided with a cluster of breaking teeth axially spaced from one another; the breaking teeth on the two roller shafts are axially arranged in a staggered way; the drive mechanisms respectively drive the two roll shafts to rotate in opposite directions; and the main unit also comprises a pair of cleaners and an adjustor for adjusting the gap between the two roll shafts. The wheel tooth type crusher can eliminate overload impact and vibration caused by non-breaking materials; after the breaking teeth on the two roll shafts are worn down, the relative gap and positions between the two roll shafts can be easily adjusted, thereby increasing the working efficiency of the breaking.

Description

technical field [0001] The invention relates to a gear tooth crusher. Background technique [0002] The gear tooth crusher is mainly used for crushing limestone, siltstone and coal and other materials with a compressive strength of ≤150MPa. Broken material. The outer surfaces of the fixed roller shaft and the movable roller shaft are equipped with crushing teeth at axial intervals. When the material enters the crushing cavity of the machine, it is subjected to the meshing force of the crushing teeth on the rotating roller shaft, so that the material is forced to pass between the crushing teeth on the fixed roller shaft and the crushing teeth on the movable roller shaft, and is squeezed by the crushing teeth at the same time. , rolling, grinding and shearing, the material begins to break, and the broken small particles are thrown to the bottom of the machine through the gap between the fixed roller shaft and the movable roller shaft along the tangential direction of the rol...

AI Technical Summary

Problems solved by technology

Such a crushing tooth structure is cumbersome to install, and it is inconvenient to replace the teeth after wear and tear. Moreover, the gap between the crushing teeth is only generated by the taper of two adjacent teeth, so that the occlusal space is too small, and it is not suitable for crushing large materials.

[0005] During the crushing process, more or less powdery materials will adhere to the ends of the crushing teeth. Due to their light weight, these powdery materials usually cannot be discharged from the machine with small particles. If things go on like this, it will inevitably affect the performance of the machine. Crushing efficiency, so it is urgent to solve this problem
