Anthracite anthracite (English name), commonly known as red stone coal or coal.Is the largest degree of coalification coal.Volatile anthracite fixed carbon content is high, the low production rate, density, high hardness, high flash point, do not smoke during burning.Black hard, metallic luster.As fat friction does not stain, fracture into shells, burns, short flame and smoke less.No coking.General carbon content over 90%, volatiles below 10%.No glue layer thickness.Calorific value of about 6000-6500 kcal/kg.The volatile matter content of very large sometimes referred to as half anthracite;Small as the high anthracite.

Specification:  0.6-1.2mm 0.8-1.8mm 1-2mm 3-6mm 4-8mm.

Application:

 Used in the drinking water and industrial water filtration purification treatment.When used according to the form of the filter using parameters, general double filter of pavement thickness for the 300-400 mm;Normal filter speed 10-14 m/h, mandatory filter speed 14-1 8 m/h;Three layers of filter material pavement thickness of 450 mm, the normal filter speed 18-20 m/h, mandatory filter speed 20 ~ 25 m/h.Filter backwashing water rinse, rinse water vapor or flush with surface.

Anthracite coal is the main application of chemical fertilizer (nitrogen, ammonia), ceramics, the manufacturing of forging;Anthracite used in blast furnace is mainly used in metallurgical industry injection (injection in the blast furnace coal mainly includes anthracite, lean coal, lean coal and gas coal).
