Nature gaphite and coal gangue are two black materials. Do you know, there are many huge use, after them were grind into the superfine powder.

Coal gangue is solid waste discharged during the coal mining process and coal washing process. At present, China's annual coal gangue is about 360 million tons, and the total amount of coal gangue resources in China has reached about 5 billion tons.

Natural graphite is an important strategic resource widely used in defense, aerospace, aviation, electronics, environmental protection, energy, advanced composite materials, medicine and other fields. The reserves of graphite resources in Heilongjiang Province rank first in the country, and its reserves account for about 45% of the world's total reserves. However, at present, Heilongjiang Province mainly produces graphite fine powder, which has problems such as short industrial chain, low added value of products, serious resource destruction, and lack of high-tech products.
 

There is a good quality grinding powder grinding mill, can be used in these two black materials powder grinding. It's Shanghai Clirik HGM Grinding Mill, the advantages of HGM Grinding Mill as follow:

1.The yield is 40% higher than other mills.

2.High utilization rate of Wear material:2-5years.

3.Adjustable particle size:325-3000mesh.

4.High safety and reliability. The design of the mill is rigorous, so no screw loosening to damage the machine.

5.Closed system, so it is the green and ideal equipment for environment protection.
