Ball mills are very important in current production applications, such as: mining mineral processing, grinding of building materials and chemical equipment, etc. Ball mills can be used for dry or wet grinding.

What are the reasons why the flushing water at the discharge port of the ball mill becomes larger:

Grinding is a part of the mineral processing process. In order to ensure the stability of production, grinding must be as stable as possible. When the amount of ore is given, the amount of water flushed at the discharge port and the amount of ore directly affect the fineness of the grinding. Many mines in China have not yet implemented grinding automation. The amount of water is directly determined by the ball mill. Manual adjustment, because the water flow in these two places is large, the increase and decrease is difficult to see, so careful observation and fine adjustments are required. As the water supply to the ball mill increases, the grinding concentration becomes thinner and the grinding fineness becomes coarser.

On the contrary, when the water supply to the ball mill is reduced, the grinding concentration becomes larger and the grinding fineness becomes finer. The flushing water at the discharge port of the ball mill becomes larger, the overflow becomes thinner, and the overflow fineness becomes thinner. On the contrary, the flushing water at the discharge port of the ball mill becomes smaller, the overflow becomes thicker, and the overflow fineness becomes coarser. Therefore, when other conditions, including the ore volume, remain unchanged, in order to improve the grinding fineness, the water supply to the ball mill can be reduced, and the flushing water at the ore discharge port of the ball mill can be increased. These two conditions are adjusted at the same time to ensure that the grinding fineness is as small as possible. Because the adjustment of grinding fineness causes changes in the slurry volume, it causes fluctuations in flotation.

Due to the operation of the ball mill, the slurry volume changes greatly, causing the flotation liquid level to be unstable. If the flotation worker does not handle it in time, it will cause changes in the metal recovery rate and grade. If the grinding fineness is adjusted to become coarser, the opposite will be true. On the premise of ensuring the grinding fineness, the ore feeding capacity of the ball mill can be increased. The amount of ore fed should be enough to meet the grinding fineness requirements without causing the ball mill to swell. The entire process requires detailed operations in every aspect.
