Proportion of ball milling and grinding balls
The grinding balls are made of 95 zirconia beads, the specific gravity of 95 zirconia beads is 6.0g/cm3, and the bulk specific gravity is 3.6g/cm3. They are placed in the ball milling tank. The ratio of materials and ball milling beads is related to the volume of the equipment tank and the fineness to be ground. related.
Roller ball mill
The barrel ball mill is generally equipped with large balls, such as zirconia balls of 30, 20, 10 and other specifications.
The barrel ball mill is characterized by large crushing ratio, simple structure, reliable operation, easy replacement of wearing parts, mature technology, and strong applicability. Ball mills are usually used for wet grinding and can also be used for dry grinding. However, the grinding efficiency of the ball mill is low, especially when the material is ground to an average particle size. Generally, it can only be ground to 8 microns under dry grinding.
The drum ball mill is generally used to grind materials with larger particles, such as lumps, large particles, powders of hundreds of microns, materials of several mm, etc.
If the particle size of the initial material is 2-3mm, if you want to grind it to 200 mesh (75 microns), you can use 20mm zirconia balls to grind it down at one time.
If you want to grind to less than 40 microns, you can match 20 and 15mm balls at a ratio of 1:1.
