Single-knife stemming crusher

Abstract

The invention discloses a single-knife stemming crusher. The single-knife stemming crusher mainly comprises a support, a hopper, a roller knife, a motor, a speed reducing belt wheel, a speed reducing transmission shaft, a bearing bush hoop, a small gear, a large gear, a belt protective cover and a gear protective cover; the support is made of square steel through welding; the hopper is made of a steel plate through welding; a discharging hole is formed in the bottom of the hopper, and stationary knife matrixes are arranged at two sides of the discharging hole; aligning holes are formed in middle positions of vertical walls at two ends; two ends of the roller knife are fixed in the aligning holes through bearings. By changing a traditional high-speed swinging arm crushing principle into a low-speed strong reamer cutting crushing principle, a rotary speed is reduced through a speed reducing device to form a low-speed strong crushing effect; a roller knife matrix and the stationary knife matrixes on the hopper are used for reamer cutting, so that high-rigidity and high-viscosity stemming is completely crushed into particles; the problem that a common crusher or pulverizer cannot crush the stemming very well, particularly the high-rigidity and high-viscosity stemming, is solved, and the crushing effect is good and the crushing speed is rapid by a structure including the roller knife matrix and the stationary knife matrixes.

Description

technical field [0001] The invention relates to a crusher, in particular to a single-knife mud crusher. Background technique [0002] The recycling and reuse of anhydrous taphole clay first needs to be crushed. Anhydrous taphole clay contains a large amount of tar pitch. When the temperature is low in winter, the molded clay block is very hard, and when the temperature is high in summer, it is very viscous. With the development of production, there are more and more demands for crushing various blasting clays, especially special blasting clays with high hardness and high viscosity. Since there is no special equipment on the market at present, borrowing ordinary crushers or pulverizers will often be stuck due to the high viscosity of the gun mud and cannot be used. Therefore it is very necessary to develop a kind of special gun mud crusher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-knife gun mud ...
