Ceramic mounted points: granular sand (usually corundum, white jade, chrome corundum, silicon carbide) made of ceramic binder sintering, the central supplemented by metal handle. Mainly grinding all kinds of metal, for the diameter of the inner wall of the grinding, mold correction. Rubber mounted points: finer particle.
Depending on its chemical and physical characteristics, silica sand is used as glass sand, foundry sand, abrasives, fillers, and hydraulic fracturing sand (also termed . Abrasive sands used in sand blasting, grinding, and polishing usually require the individual particles to be nearly the same size and somewhat angular with.
Sand used for building, such as this, and the sand of beaches outside the tropics—70% of the world's sand, in fact—is made of quartz, also known as silica, produced by the grinding and scouring of millions of years of weathering and glaciation. The sand of tropical beaches is different. It is "biogenic", or produced by life.
