202338· The filling rate of bearing steel balls in the grinding operation of mining plants is generally 50%~60%. It is not an effective filling rate if based on each dressing plant’s specific conditions. Therefore, it must determine the balls loaded according to the beneficiation test. 4. Adequate steel ball specifications and configurationsDesign and simulation of gear box for stone crushing ball mill,11· Steel balls occupied volume = 4.71–3.0615 = 1.6485 m 3. The weight of the rock material = volume * density = 3.0615 * 2400 = 7347.6 kg. The weight of the steel balls material = volume * density = 1.6485 * 7850 = 12,940.725 kg. Total weight of the material = 7,347.6 + 12,940.725 = 20,288.325 kg.
