Description

Crushing production line

technical field

The utility model relates to a crushing production line, which belongs to the field of crushing machinery.

Background technique

At present, the equipment used for crushing in China is generally a single crushing equipment, that is, the material is usually crushed by a pulverizer for a period of time and then sieved by a sieve with a certain number of meshes. Materials that do not meet the particle size requirements continue to be put into the pulverizer. Crushing in the middle, and so on, until all the materials are crushed and meet the requirements. Although this crushing method can crush the material to a certain particle size to make it into a qualified product, the production efficiency is too low to meet the scale production; on the other hand, a large amount of dust will be generated during the crushing process of the crusher. In the case of a dust collection device, it will cause a lot of dust pollution to the environment.

In addition, when the pulverizer rotates at high speed, it will generate a lot of heat. If the heat is not transferred in time, it is easy to cause damage to the pulverizer or denaturation of the pulverized material. The cooling method of the prior art is usually in the pulverizer. Cooling water is passed into the bearing of the pulverizer, but because there is a gap between the rotating part and the stationary part of the pulverizer, this method is likely to cause leakage of cooling water, which will further affect the pulverized material.
