Zirconia beads are high-quality grinding media in the grinding materials of ball mills, and the grinding efficiency is very good even in pin-type sand mills with huge impact. So, how does the zirconia beads of Shanghai Zhimo achieve this?

1. Raw materials: First, choose good raw materials. The quality of zirconia powder directly affects the quality and grinding performance of zirconia beads. The particle size of the zirconia powder raw material will also directly affect the wear resistance of the beads.

2. Sintering aids: followed by sintering aids and the sintering process. The sintering aids are used to reduce the sintering temperature, thereby improving the microstructure of zirconia ceramics and improving their wear resistance. Among them, the temperature of the products we control during the sintering process is higher than that of other manufacturers in the industry, and the products are more stable and pressure resistant; in addition to the automated production process, the zirconium beads we produce need to withstand two pressure tester tests; In the process, there are only 5 domestic manufacturers of sorting machines, and Zhimo is one of them. In addition, we strictly control each production technology gate to avoid the appearance of substandard products.

3. Forming: There are two forming methods on the market now: roll forming and isostatic pressing. Roll forming and isostatic pressing technology have changed other forming defects such as hollow and layered unevenness.
