the grinding barrel also called silicon carbide grinding barrel, it is mabe by reaction bonded silicon carbide ceramic,the silicon carbide grinding barrel need be precision machining in CNC machining center. Silicon carbide sleeve not only has excellent abrasion resistance performance, but also has high hardness, high size and accuracy, and long service life.

the product has light weight, high hardness, corrosion resistance, high temperature resistance and other properties. It's better than traditional zirconia ceramis in resistance to erosion and wear(low abrasion value can prevent material from pollution).The coefficient of thermal conductivity is 130 W/m.K (20 ℃),it is the best cooling effect ceramic material which has the advantages to control the temperature rise in the process of equipment operation. The barrel is through the casting or isostatic pressing molding forming technology, can be effective isolation lumen and outer shell, make it is not ubject to corrosion and scouring. Service life is 5 to 10 times of general wear-resisting material, integrated operation cost is low.
