Find Verified Anthracite Coal Suppliers, Manufacturers and Wholesalers

Granular Anthracite Coal Filter Media are made from high-quality raw coal and selected, broken, and sieved twice.

The Granular Anthracite Coal Filter Media has good appearance glossiness, ball shape, high mechanical strength, good compression resistance, stable chemical properties, no toxic substances, and wear resistance.

Granular Anthracite Coal Filter Media does not dissolve in acidic, neutral, or alkaline water. In addition, the anthracite particles have rough surface, good adsorption capacity, high porosity (â?¥52%), and high pollution-bearing capacity.

Granular Anthracite Coal Filter Media can save a large amount of backwash water and electricity due to its light weight and low backwashing strength.

The Electrical Calcined Anthracite is used the best quality anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calciner with results in eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation.
It has good characteristics with low ash, low resistvity, low sulphur, high carbon and high density. It is the best material for high quality carbon products to production of electrode, and used in cathode blocks for aluminum industry.
