Crushing pair with axial shearing crushing function

Abstract

The invention discloses a crushing pair with an axial shearing crushing function, which comprises a fixed cone, a movable cone, a mortar rolling wall, and a crushing wall, wherein the mortar rolling wall is fixed at the inner side of the fixed cone, the crushing wall is fixed at the outer side of the movable cone and the crushing wall is sheathed in the mortar rolling wall so as to form the crushing pair; a closed annular rack is arranged on the crushing pair at the outer side of the movable cone and the horizontal plane where the annular rack is positioned is vertical to the axis center line of the movable cone; and another closed annular rack is arranged on the mortar rolling wall at the inner side of the fixed cone and the horizontal plane where the annular rack is positioned is vertical to the axis center line of the fixed cone. Due to the design of the annular racks arranged on the crushing pair, the solid light panel design in the prior art can be replaced, and axial shearing crushing force can be formed due to the up-down relative motion of the movable cone and the fixed cone. So that the crushing principle of a cone machine in the prior art, which mainly includes squeezing and squashing modes, can be improved to be a preferable shearing crushing mechanism based on the comprehensive application of multiple crushing modes such as chopping, folding and tumbling. Therefore, the crushing efficiency of the cone machine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cone crushers, in particular to a crushing pair with axial shearing and crushing functions. Background technique [0002] Cone crusher, also known as cone machine. In the past ten years, cone crushers have sprung up in the market and developed rapidly, and are gradually replacing the widely used jaw crushers and impact crushers, impact crushers, and hammer crushers with functions such as shaping or ultra-fine crushing (such as sand making). There are two reasons: first, the extrusion crushing mechanism of the cone crusher is more economical and efficient than the impact and hammer crushing mechanisms of impact crushing; It works for the whole process of crushing (half of the return stroke of the jaw crusher does not work), and the work efficiency is greatly improved. [0003] The working principle of the cone machine is to set an eccentric angle by the moving cone, so that when the moving cone rotates, ...

AI Technical Summary

Problems solved by technology

Therefore, the cone crusher loses the crushing force in the radial direction (there is only normal positive pressure crushing force between the crushing wall and the material), which determines the congenital defect of the cone crusher - no tangential shear crushing function
