What Is Anthracite

Anthracite is a hard, dense, and highly glossy coal mine variety. Among all coal varieties, although anthracite has a lower calorific value, it has the highest carbon content and the lowest impurity content.
Anthracite, commonly known as white coal or red coal. It is the coal with the highest degree of coalification. Anthracite has a high fixed carbon content, low volatile matter yield, high density, high hardness, high ignition point, and does not emit smoke during combustion. Black hard, with a metallic luster. Friction with grease does not cause contamination, the fracture surface is in the shape of a shell, and the flame is short and has little smoke when burning. Not coking. Generally, the carbon content is above 90% and the volatile matter is below 10%. No thickness of glial layer. The calorific value is approximately 6000-6500 kcal/kg. Sometimes, those with extremely high volatile matter content are called semi smokeless coal; The extremely small ones are called high smokeless coal.
standard coal equivalent
The standard filter material is made of high-quality carbon blocks that have been carefully selected, crushed, and screened. It has a good appearance and luster, and is in the form of polygonal particles with strong compressive and wear-resistant properties. It is generally used for double-layer and three-layer filtration.
TJP filter material
TJP type smokeless coal filter material is produced according to the standards of Japanese Shuidao Jushi Company, and its quality fully meets Japanese standards. It is mainly used for the treatment of steel rolling circulating water in the steel system and the deep treatment of wastewater in the 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 type of filter material used in the water treatment industry, which is specially selected from deep well minerals and has the highest percentage of carbon content. Anthracite filter material is manually classified to reduce irrelevant minerals and ash content. After filtration and flushing, it is ensured to be suitable for water filtration. Due to its good solid particle retention ability, anthracite can reliably improve its ability to remove suspended particles.
