Novel tooth type oppositely-rolling roller crusher

Abstract

The invention aims at designing a novel tooth type oppositely-rolling roller crusher to meet the requirement that raw materials with complicated shapes, such as building garbage, shale, gangues and the like, are extruded and pulverized. For achieving the purpose, the novel tooth type oppositely-rolling roller crusher is provided with two oppositely rotating rollers which are respectively installed on a main shaft, and the roller surfaces of the rollers are of a concave-convex tooth shape. Because the roller surfaces are of the concave-convex tooth shape, the novel tooth type oppositely-rolling roller crusher provided by the invention can fully extrude and pulverize mediums and is suitable for extruding and pulverizing the raw materials with complicated shapes, such as the building garbage, the shale, the gangue and the like; and because the contact surfaces of the rollers are enlarged, the working efficiency is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of building material machinery manufacturing, and in particular relates to a pair of toothed roller crushing equipment. Background technique [0002] At present, the roller crushers commonly used by brick and tile production enterprises mainly have the following deficiencies and defects. One is that ordinary double-roll crushers can only crush some smaller particles of raw materials, and cannot enter between the two rollers for crushing of larger raw materials. The second is that for those raw materials with complex shapes such as complex construction waste, shale, and coal gangue, which are too high in strength, it is easy to slip and bite into them, and they cannot be fully squeezed and crushed. In this way, the requirements for raw materials are relatively high in the use process, and the work efficiency is affected to a large extent, which brings unnecessary losses to brick and tile production enterpris...

AI Technical Summary

Problems solved by technology

One is that ordinary double-roll crushers can only crush some small-grained raw materials, and cannot enter between the two rollers for crushing of larger raw materials.

Second, for those raw materials with complex shapes and high strength, such as complex construction waste, shale, and coal gangue, it is easy to slip and bite, and it cannot be fully squeezed and crushed.

In this way, the requirements for raw materials are relatively high in the process of use, and the work efficiency is greatly affected, which brings unnecessary losses to brick and tile production enterprises.
