Natural emery, also known as garnet sand because of its conditions, is a silicate mineral.Emery raw materials can be divided into several grades after simple processing, screening and grading, and other methods of grinding materials, hardness is very high, about 7 to 8 degrees mohs.The usual are brown powdery particles.After grinding, can be used as a grinding powder, can be used for polishing paper, can also be used for grinding wheel and stone friction surface.Production and use of a long history, ancient China has the use of emery grinding crystal glass, a variety of jade history.The 1840s and exported to the east.There are three major categories: coarse, medium and fine.All kinds of mesh size uniform, uniform particle shape, edge called Angle crystal, sharp edge, high grinding force.For stone industry grinding marble and other soft materials.Glass industry grinding glass edge, television tube, optical instruments, lenses, prisms, clocks and other glass.Metal industry sandblasting, derusting, grinding.The printing industry grinds the rubber plate, as well as the light industry processes the plastic sample, the leather, the sandpaper and so on USES.The grinding force of natural emery is slightly lower than that of electric furnace white corundum, but it is capricious and strong.Grinding surface fine and uniform, can improve product quality.The grinding time of natural emery is short, the benefit is high, the price is low, can make up for the short life.
