2. Optimal milling efficiency is achieved when the milling balls occupy 50-55% of the milling jar volume and the enamel frit occupies 22-25% of the volume. Typically, the milling balls used are available in three sizes. Smaller balls provide finer milling, while larger balls crush the material being ground. Smaller balls are more efficient than larger balls because they have a larger number of balls and a larger total contact area. milling ball input ratio:
20-25% 50 mm
60-50% 40 mm
20-25% 30 mm
3. Selection of milling jar lining and milling balls: Domestically produced high-alumina milling balls and lining bricks come in various alumina (Al2O3) contents; including 92% Al2O3, 75% Al2O3, 65% Al2O3, 50% Al2O3, etc. Of course, 92% Al2O3 is the best. A simple test method: Hold two milling balls of the same size in your hands and then forcefully strike them together; if they do not break, they are usable.

4. The inner layer of the grinder and the wear condition of the milling balls should be checked regularly. The size of the added milling balls should be the same as the initial large milling balls. Routine inspection methods are as follows:
(1) Inspect the inner wall of the grinder every 150-170 milling cycles. (If any gaps in the lining bricks fall off, they can be filled with white cement mixed with water).
(2) Inspect the milling balls every 50 milling cycles.
(3) Records must be kept for each milling cycle, inspection, addition of milling balls, or replacement.
