Mohs hardness and Vickers hardness are commonly used hardness indexes. The hardness of commonly used ceramic grinding balls can refer to the specific information on the Internet. From the point of view of the contact of the ceramic grinding ball to the ball mill, the wear of the ceramic grinding ball with high hardness to the contact is relatively large, but the optimum can be achieved by adjusting the parameters such as the filling amount of the grinding ceramic ball, the viscosity of the slurry, and the flow rate. Optimize the effect. Then it is necessary to know the specific value of the density of the ceramic grinding balls, that is, the specific gravity of the ceramic balls. In actual production, high aluminum ceramic ball specific gravity is divided into two types, namely bulk density (true density, true specific gravity) and bulk density (false specific gravity).
The former is the true density of high aluminum balls, and the latter is the density of high aluminum balls stacked up. In general, the higher the weight of the high aluminum ball, the greater the impulse, the higher the grinding efficiency, but there will also be a certain impact on the wear of the ball mill's contact parts (inner cylinder wall, dispersion disc, etc.), so the key is the slurry The viscosity of the material and the flow rate. Buyers should also know that any quality of ceramic balls will wear to varying degrees during the grinding process, which will have a certain impact on the performance of the slurry, so when buying ceramic grinding balls, you must consider The effect of composition on the slurry.
