Compound tooth-shaped conical broken grinding head with point press teeth and long strip sieve pores

Abstract

A compound tooth-shaped conical broken grinding head with point press teeth and long strip sieve pores consists of an inner cone sleeve connected on a main shaft through keys, an upper inner cone lining board, a lower inner cone lining board, an outer cone sleeve, an upper outer cone lining board and a lower outer cone lining board, wherein a point press lug boss on an impact face of an impact tooth of the upper inner cone lining board and the point press teeth on the upper outer cone lining board efficiently carry out point press, splitting and breaking on big-lump materials; and the long strip sieve pores on the lower inner cone lining board and lower outer cone lining board discharge a material of which the grain size meets the standard, prevent repeated fragmentation and reduce the consumption of a grinding material so as to achieve the aims of energy conservation and consumption reduction. The split type lining boards are easy to mount and repair.

Description

Technical field [0001] The invention relates to the technical field of crushing equipment for brittle and hard materials, in particular to a composite tooth-shaped conical crushing grinding head with point pressing teeth and long sieve holes that simultaneously utilizes impact, breaking, splitting, shearing and other force applying methods. technical background [0002] Among the currently known composite tooth-shaped cone crushing grinding head technologies: Patent name: Multi-tooth-shaped combined cone crushing grinding head (patent number: 200420010045.9) The rough material crushing part composed of impact teeth and large trapezoidal teeth solves the problem of material breaking and crushing . However, for materials with large blockiness, the more labor-saving splitting force cannot be used-that is, point pressure and linear pressure; the finely divided parts composed of the inner and lower cone lining slat teeth and the outer lower cone lining slat teeth, It solves the proble...

Problems solved by technology

However, for materials with large lumps, the more labor-saving splitting force cannot be used—that is, point pressure and line pressure; It solves the problem of extrusion, shearing and crushing of materials, but there is poor discharge of qualified materials in this part, resulting in repeated crushing, which increases the loss of grinding materials
