Zirconium silicate ball zirconia beads are firstly made of micron-sized and sub-nano-sized raw materials, and are made by advanced technology. The technical indexes and performances have reached the international advanced level. Zirconium silicate ball is mainly used in ultral industry. High grinding efficiency: Due to the high density of zirconium beads, it has a higher grinding kinetic energy at the same moving speed, and the grinding efficiency is 2-3 times higher than that of ordinary ceramic beads. You can get better results. Impact resistance, low wear: Due to the high content of ZrO2, it has the advantages of high density, high toughness, low abrasion, no broken ball, peeling, etc., and it has little pollution to the abrasive dispersion. The abrasion is 4-10 times lower than that of ordinary ceramic beads....

Method for detecting the wear rate of zirconia balls under the condition of material grinding In a 1L alumina ceramic tank, 1KG of zirconia balls to be tested are charged, 150g of water, 300g of zirconium silicate (zircon sand), 2g of sodium tripolyphosphate, capped, and fixed in a fast mill. The mill was continuously ground for 5 hours, and the zirconia balls were taken out, washed, dried, and weighed. The belt wear (Rm) of the qualified zirconia balls is required to be less than 0.15%/5h, or less than 0.03%/h. 2. Method for detecting the wear rate of zirconia balls without grinding (self-grinding) grinding conditions In a volume of 1L alumina ceramic tank, 700g of zirconia balls to be tested were placed, 300g of water was added, capped, fixed on a turntable in a fast mill for 5 hours, and the zirconia balls were taken out and dried. , weighing. The wear rate (Rs) of a qualified zirconia ball is required to be less than 0.3%/5h, or less than 0.06%/h. ...

the biggest problem is that the rubber will cause the porous of the grinding wheel to block. Once the porous are blocked, the grinding temperature will increase. In addition to the loss of the cutting force of the grinding wheel, the surface of the rubber will also dissolve, and further cause undesirable conditions such as uneven surface, burrs and even cracks. ...
