Application of wear-resistant steel balls in the start-up process of ball mills

　　After the ball mill is turned on and running normally, the addition of wear-resistant steel balls to each shift's ball mill should be done at a ratio of 3:4:3. Note: The addition of wear-resistant steel balls for ball mills is only for the first time. Because during the normal operation of the ball mill, the reasonable grinding between the wear-resistant steel balls and steel balls, steel balls and ore, and steel balls and the lining plate of the ball mill will increase the wear, making the large ball mill small and medium ball mill small balls. So under normal circumstances, there is no need to add more balls. The situation of adding small balls is when there is no monomer dissociation in the useful mineral particle size, and when the fineness of the grinding machine cannot meet the flotation requirements, an appropriate amount of small balls can be added. The wear-resistant steel balls of the ball mill constantly wear during operation. In order to maintain the ball load filling rate and reasonable ball ratio, and to maintain the stable operation of the ball mill, it is necessary to carry out reasonable ball supplementation and low compensation for wear.

　　The weight of wear-resistant steel balls added to the ball mill is determined by the quality of the wear-resistant steel balls. The quality of the wear-resistant steel balls in the ball mill determines the amount of ore consumed per ton. It is best for ball mill accessory factories to use new wear-resistant ball mills with wear-resistant steel balls. The best ball mill wear-resistant steel ball addition is calculated based on the amount of ore processed per ton (i.e. 0.8 kg per ton of ore added). Generally, a ball mill wear-resistant steel ball requires (1 kg -1.2 kg) to process one ton of ore. Size ratio of wear-resistant steel balls in ball mills: The ratio varies for different ball mill models. The diameter of the ball mill is below 2500mm, and the sizes of wear-resistant steel balls for adding wear-resistant ball mills are 100mm, 80mm, and 60mm. The diameter of the ball mill is above 2500mm, and the size of the wear-resistant steel balls added to the ball mill is 120mm, 100mm, and 80mm.
