Natural corundum emery Profile

Emery (sic), also known as silicon carbide, silicon carbide is a colorless H&X brown fused aluminium oxide of pure colorless powder particles. Density of 3.06 to 3.20, Mohs hardness of about 9.5 degrees. Pure diamond abrasive powder can be done after grinding, polishing can be made of paper, can also be made of the friction surface of the grinding wheel and a whetstone.
Natural corundum also called garnet sand, silicate minerals. By hydraulic sorting, grinding material machining, classification and other methods of screening. Natural H&X buy silica into coarse mesh, mesh, breakdown into three categories, which coarse mesh black and red, the head is pale red, breakdown of red and white. Beijing Ming Jian environmental technology produces a variety of diamond mesh filter uniform particle size, particle shape evenly into the water chestnut crystals have sharp edges, grinding force.
