What is the application of vertical superfine grinding mill for grinding anthracite in cathode material?

GKLMX Vertical superfine grinding mill is a large-scale equipment for industrial pulverization. It can process non-metallic ores, pulverized coal, anthracite, calcined coke, petroleum coke and other industrial materials. Next, let’s take you to know what role the vertical superfine grinding mill plays in the application of anthracite coal in negative electrode materials.

At present, anode material enterprises generally use needle coke as raw material to prepare artificial graphite anode through crushing, coating, graphitization and other processes. Anthracite has the characteristics of high carbon content, low volatile, compact structure, high hardness and no smoke during combustion. As a fuel, it is widely used in civil use, power generation and steel smelting. It can also be used as a raw material for gas production and synthetic ammonia production. In carbon production, anthracite is often used to produce various carbon blocks and electrode pastes, and its application in the field of lithium-ion battery cathode is rarely reported.

Graphite anode materials for anthracite based lithium ion batteries were prepared by simple processes such as coarse crushing, ultrafine grinding and graphitization. Anthracite based graphite particles are mostly spherical, which is very different from the common needle coke based graphite anode in microstructure. The cycle data show that the cycle stability of anthracite cornerstone graphite anode is much better than that of needle coke based graphite anode.

Superfine grinding is essential in the production of negative electrode materials from anthracite. As mentioned above, it needs to be ground to 16-18um. The grinding particle size of Guikuang’s anthracite coal grinding mill machine can be adjusted arbitrarily between 44-7um. It is a mechanical equipment more suitable for the front-end grinding of anthracite.
