Brown Fused Alumina is fused bauxite in an tilting arc furnace or fixed furnace by high temperature. It shows brown color and its main chemical composition is Al2O3,it's also have content little Al2O3,SiO2,Fe2O3,TiO2,CaO. After crusher,,sieve to different grain size, water cleaning or wind cleaning.,then used for different application,it is called teeth of industry .It has suitable for grinding ,polishing, bonded abrasives, coated abrasive. In refractory industry,it can used for lining mixture,pouring materials,castable and refractory brick. Size Available: . For Coated Abrasive Grain Size P12 , P14 ,P16,.P20 ,P24 ,P30 ,P36 ,P40 ,P60, P80 ,P100, . P180, P220 ..... For Bonded Abrasive Grain Size F12 , F14 ,F16,.F20 ,F24 ,F30 ,F36 ,F40 ,F60, F80 ,F100, . F180, P220 Refractory Application: 0-1mm,1-3mm,3-5mm,5-8mm,200mesh,325mesh Other sizes can be produced by customer's special request.. Smelting Furnace:We have brown corundum dumping furnace and fixed furnace,can reach different customer special requirement. The dumping furnace have very small crystal than fixed furnace,so the products have the high toughness and good anti-impact ability,It is well used in vitrified application and can improve the grinding efficiency. Bulk Density:We have barmac ,ball mill,roll mill production line,can crushed different bulk density as customer's special requirement
