anthracite belongs to environmental protection coal.

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.

Grease friction does not pollute, and the fracture is shell-shaped, and the flame is short and less smoke when burning. No coking. Generally, the carbon content is above 9% and the volatile matter is below 1%. No glue layer thickness. The calorific value is about 6-65 kcal/kg. Sometimes the volatile content is called semi-anthracite coal; Extra small ones are called high anthracite.

Extended information

Anthracite type

1. Standard coal

The standard filter material is made of high-quality carbon blocks through selection, crushing and screening, with good gloss, polygonal granules and strong compression and wear resistance, and is generally used for double-layer and triple-layer filtration.

2. TJP filter material

TJP anthracite filter material is produced according to the standards of Japan Waterway Jurassic Company, and its quality completely meets the Japanese standards. It is mainly used for circulating water treatment of steel rolling in iron and steel system and advanced treatment of sewage in petrochemical industry. At the same time, it is also suitable for advanced water filtration in precision manufacturing and aerospace navigation.

anthracite filter material is a kind of filter material used in water treatment industry, which is specially selected from deep well minerals and has the highest carbon content percentage. Anthracite filter material is classified manually, which can reduce irrelevant minerals and ash content. After filtration and washing, it is ensured to be suitable for water filtration. Because of its good solid particle retention ability, anthracite can reliably improve the removal ability of suspended particles.
