Problems solved by technology

[0005] In the actual use process, when the crushing teeth squeeze and crush the material, when encountering a small part of hard material, when the hardness is greater than the hardness of the crushing teeth, due to the structural design of the crushing teeth, the crushing teeth will The local stress strength of the machine is weak, so it will cause hard damage to the crushing teeth, causing the crushing teeth to be easily worn or even broken, which will lead to a reduction in the crushing effect and efficiency

Embodiment 1

[0032] Embodiment one: roller mill, such as figure 1 and figure 2 As shown, the crushing chamber 2 driven by the motor through the pulley is installed on the frame 1, and the rollers 3 are installed in the crushing chamber 2. The rollers 3 are arranged in groups, which can be set in two or more groups for multiple crushing. Each group of rollers 3 cooperate with each other, and a plurality of crushing teeth 4 are installed on the surrounding surface of each roller 3, and a pit 5 is provided at the same time for the crushing teeth 4 on the matching roller 3 to extend in, thereby crushing the material.

[0033] When installing the crushing teeth 4, the crushing teeth 4 are installed in a detachable manner. First, an installation groove 6 is provided on the surrounding surface of the roller 3. The crushing teeth 4 can be directly stuck in the installation groove 6, and fixed by interference fit. In this way, when disassembly is needed in the later stage, the crushing teeth 4 ar...

Abstract

The invention discloses a roll crusher, relates to the field of building material crushing, and aims at solving the problem that the crushing efficiency is influenced because a roll is liable to be damaged during material crushing of a crusher. The essential of the technical scheme is as follows: the roll crusher comprises at least two rolls which are synchronously and reversely driven, wherein crushing teeth are formed on the surrounding surface of each roll, and pits matched with the crushing teeth are formed in the roll which is matched with the previous roll; and the crushing teeth are detachably and fixedly connected to each roll. According to the roll crusher, the crushing teeth on the surface of each roll are configured to be detachable, so that replacement is facilitated, and thenthe crushing efficiency is increased.

Description

technical field [0001] The invention relates to the field of crushing of building materials, more specifically, it relates to a roller crusher. Background technique [0002] Roller mill is a kind of crushing equipment with a simple structure, and it is still used in cement, silicate and other industrial sectors, mainly for medium and fine crushing of ore or building materials. [0003] In the usual twin-roller pulverizer, the crushing process of coarse materials is carried out by means of two motor-driven rollers. The rollers are usually oriented horizontally. The central axes of the rollers are arranged parallel to each other and the directions of rotation are opposite. The rotation introduces the material from above the roller gap into the roller gap and is crushed by the crushing teeth of the rollers, and then the material is output from below it. [0004] In order to improve the crushing efficiency, a double-roller pulverizer is currently disclosed on the market. It is ...
