Anthracite, commonly known as white coal or red coal. It is the coal with the largest degree of coalification. Anthracite has high fixed carbon content, low volatile yield, high density, high hardness and high ignition point, and does not smoke when burning. Black is hard and metallic.
Friction with grease will not pollute, the fracture is shell-shaped, and the flame is short and smoke is less when burning. There is no coking. Generally, the carbon content is above 90%, and the volatile matter is below 10%. No glue layer thickness. The calorific value is about 6000-6500 kcal/kg. Sometimes the volatile matter is called semi-anthracite coal; Particularly small ones are called high anthracite.

Anthracite type
1, standard coal
The standard filter material is made of high-quality carbon blocks, which are carefully selected, crushed and screened. Good gloss, polygonal particles, strong compression and wear resistance, generally used for double-layer and three-layer filtration.
2.TJP filter material
TJP anthracite filter material is produced according to the standards of Jurassic Company of Japan Waterway, and the quality is in full compliance with Japanese standards. It is mainly used for circulating water treatment of steel rolling in iron and steel system and advanced treatment of petrochemical wastewater. At the same time, it is also suitable for advanced water filtration in precision manufacturing and aerospace fields.
Anthracite filter material is a kind of filter material in water treatment industry, which is specially selected from deep well minerals and has the highest carbon percentage. Anthracite filter material is classified manually, which can reduce irrelevant minerals and ash. After filtration and washing, it is guaranteed to be suitable for water filtration. Because anthracite has good solid particle interception ability, it can reliably improve the removal ability of suspended particles.
