Company is specialized in the production of medium production enterprises, in order to produce zirconia, alumina, silicon nitride and other fine ceramic structure. The company independently developed and mass production of talc porcelain beads and alumina grinding beads, filling the gap of domestic high performance ceramic grinding media. Company's main products are: evaporation boat, zirconium beads, mechanical seals, sand grinding machine, evaporation, etc.. Company from the United States to introduce the production of zirconia grinding media, become one of the first to start the production of zirconia grinding media production, and have independent research and development of JZM95, JZM80, JZM64, JZM30 and other high performance, low wear and grinding beads. Sand mill, the use of eccentric disc grinding structure, and in a certain order, the system overcomes the shortcomings of traditional grinding media distribution, so that the medium can get the biggest energy transfer, high efficiency, the use of double end face mechanical seal, sealing effect is good, reliable operation, the separation system using large flow LDC dynamic gate slot, the flow area of the flow area, 0.05-2.0mm, can use 0.1mm above ground medium.
