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. 1.specification indexes: Fixed carbon 90% Ash 8% Volatile 1.2% Sulfur 0.35% Moisture 0.5% Resistivity 750 2 Fixed carbon 93% Ash 6% Volatile 1.0% Sulfur 0.30% Moisture 0.5% Resistivity 650 3 Fixed carbon 95% Ash 4% Volatile 1.0% Sulfur 0.25% Moisture 0.5% Resistivity 600 2.Real Density:1.80-1.90 G/CM3 min 3.Size:0-20mm,90%min; 1-20mm, 90%min; 1-10mm, 90%min,or at customers option; 4.Packing:In 1200kgs big bag; In 1000kgs big bag; In 25kgs small bag, then into 1000kgs big bag; or 25kgs or 50kgs small bag, then put into containers directly; or at customerâ??s option; 5.Payment:cash, letter of credit.
