Embodiment Construction

[0013] in Figure 1 to Figure 4 Among them, a split upper inner cone liner (4) is installed on a main shaft (1) and an inner cone sleeve (3) by a key (2). There are multiple rows of impact teeth (5) in the transverse direction, and the impact surface of the impact teeth is provided with a triangular point pressing boss (23). The upper outer cone liner (9) installed on the outer cone sleeve (10) has a bit of pressing teeth (7). The lower inner cone lining plate (11) and the lower outer cone lining plate (12) are respectively provided with bar-shaped tooth transverse teeth (15) and (13) with an axial inclination angle to form an inverted triangular crushing cavity. When a large piece of material enters the crushing cavity, it is split and broken by the point pressing boss (7) on the impact tooth (5) and the point pressing tooth (7) on the upper outer cone (9). It is stuck on two rows of large trapezoidal teeth (8), and the top plan view is a notched space, and then the impact teeth (...

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...
