Description

A graphite circulating continuous pulverizing device and method

Technical Field

The invention relates to the technical field of graphite pulverization, and in particular to a graphite circulating continuous pulverization device and method.

Background technique

As an important industrial raw material, graphite is widely used in metallurgy, chemical industry, machinery and other fields. In the processing of graphite, crushing is an indispensable part. However, there are some common problems in the existing graphite crushing devices and methods, which affect the efficiency and quality of graphite processing.

First, the problem of feed blockage is particularly prominent. Due to the physical properties of graphite, such as strong viscosity and large particle size, the material is prone to blockage at the feed port during the crushing process. Especially in an environment with high humidity, the viscosity of graphite increases, and the blockage problem is more serious. In addition, if the material contains large pieces of material or foreign matter, it is easy to cause blockage inside the crusher, causing equipment shutdown and affecting production efficiency.

Secondly, the dust problem during the crushing process is also a difficult problem that needs to be solved urgently. During the graphite crushing process, a large amount of dust will be generated due to the collision between the high-speed rotating crushing blades and the material. This dust will not only harm the health of the operators, but also pollute the working environment and may even cause safety accidents such as fires. At the same time, long-term accumulated dust will also interfere with the normal operation of the equipment and reduce the service life of the equipment.

In order to solve the above problems, some attempts and improvements have been made to the existing graphite crushing devices and methods. For example, by optimizing the structure of the crusher to improve the crushing efficiency; or adding a dust removal device to collect and treat the dust generated during the crushing process. However, these improvement measures often have problems such as high cost and limited effect, and cannot fundamentally solve the problems of material blockage and dust. For this reason, we provide a graphite circulating continuous crushing device and method.
