Three-dimensional inclined tooth roll crusher

Abstract

A three-dimensional inclined toothed roller crusher, comprising a casing, a plurality of power devices mounted on the casing, a base located at one end of the casing away from the power device, a plurality of groups of toothed rollers, a plurality of toothed rollers installed on each toothed roller A number of crushing teeth on the upper part, and a number of blocking bodies installed on the inner wall of the casing; the toothed rollers correspond to the power device one-to-one respectively; each of the toothed rollers is respectively connected to the base and the corresponding power device; the teeth The rollers are evenly distributed in the casing around the central axis of the casing and are inclined from the base toward the power unit. The three-dimensional inclined toothed roller crusher of the present invention achieves the characteristics of large crushing ratio, high screening efficiency, large processing capacity and three-dimensional crushing through the cooperation of the casing and the toothed rollers through several toothed rollers arranged obliquely in space, thereby effectively improving the Crushing efficiency and crushing quality.

Description

technical field [0001] The invention relates to a crusher for mining, especially a three-dimensional inclined toothed roller crusher for coal and similar materials. Background technique [0002] In existing mining equipment, a double-toothed roller screening crusher is often used for crushing coal and other materials; ordinary double-toothed roller screening crushers are arranged in parallel with two toothed rollers, and the reverse rotation can not prevent the crushing teeth from breaking. Large pieces of material that slide down in the gap are crushed. [0003] However, due to the parallel arrangement of the two toothed rollers, the screening is only carried out in one plane, and it is easy to miss long materials, and the discharge particle size can only be controlled in two dimensions, and the efficiency is limited; Occupied by two toothed rollers, the screening efficiency is not high, and the phenomenon of material blocking is easy to occur; because the double toothed r...

[0002] In existing mining equipment, a double-toothed roller screening crusher is often used for crushing coal and other materials; an ordinary double-toothed roller screening crusher is arranged in parallel with two toothed rollers, and the reverse rotation can not prevent the crushing teeth from breaking. Large pieces of material that slide down in the gap are crushed

[0003] However, due to the parallel arrangement of the two toothed rollers, the screening is only carried out in one plane, and it is easy to miss long materials, and the discharge particle size can only be controlled in two dimensions, and the efficiency is limited; Occupied by two toothed rollers, the screening efficiency is not high, and material blocking is prone to occur; because the double-toothed roller crusher uses the shear crushing mechanism, its maximum feeding size is limited by the size that can be clamped by the two crushing teeth limit, resulting in a relatively small breakage
