Crusher

Abstract

The invention discloses a crusher. The crusher comprises a shell (1), and a primary crushing mechanism and a secondary crushing mechanism which are arranged in the shell (1), wherein the primary crushing mechanism is arranged above the secondary crushing mechanism; the primary crushing mechanism is used for driving materials to be crushed to move downwards for primary crushing; the secondary crushing mechanism is used for performing secondary crushing on the materials subjected to the primary crushing. The crusher has the advantage of the conventional crusher, can be applied widely, and has high adaptability to rubber products of different types and different properties. Products are uniform in shapes, and notches are tidy and attractive. The crusher is suitable for rubber products with very high toughness and viscoelasticity, integrates a plurality of cutting ways, and has high product treatment adaptability and high crushing efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical structures; in particular, it relates to a crusher. Background technique [0002] Crushing is a process in which an external force is applied to the crushed material to overcome the cohesive force between the molecules of the material and split the large material into several small pieces. Crushing operations are divided into mechanical energy crushing and non-mechanical energy crushing such as electrical energy and thermal energy according to the energy consumed. In industry, mechanical force is mainly used for crushing, and the methods are as follows: crushing, chopping, breaking, grinding, impact crushing, etc. Mechanical crushing is more suitable for the crushing of brittle and hard materials, and has been widely used in the material treatment process of the mining and metallurgical industry. However, for materials with high toughness, such as rubber, the above-mentioned mechanical crushi...

AI Technical Summary

Problems solved by technology

However, for materials with high toughness, such as rubber, the above-mentioned mechanical crushing methods cannot effectively complete the crushing task.

[0003] At present, most of the rubber crushers used in the market adopt the shear crushing method, which can process ordinary rubber products with average toughness. However, when encountering special rubber products with high toughness and viscoelasticity, the rubber will be deformed and squeezed. Between the blades, it cannot be cut effectively, the crushing efficiency is low or even the crushing task cannot be completed
