There are many factors that affect the grinding process of mineral processing ball mill equipment. Common ones include ball mill structure, ore properties, operating conditions, etc. Mineral processing equipment The ball mill itself has a simple structure and can be matched with a variety of mineral processing equipment, such as vibrating screens, hydrocyclones, etc., to form closed-circuit grinding with large output and high efficiency. The properties of ore and operating conditions are of critical significance to the quality of grinding products. In order to ensure better grinding effect of the mineral processing production line, the operator is required to adjust the ore feeding amount of the mineral processing ball mill at any time according to the particle size, hardness, etc. of the ore. In addition, there are some factors that will also affect the grinding process of the mineral processing ball mill, such as the ball mill revolution speed is too fast or too slow, the steel balls are not installed reasonably, the inclination angle of the classifier is large, the spiral rotates fast, etc., which will affect the grinding fineness. degree of impact.

In addition, if a screening step is added before the slurry enters the ball mill, the purpose is to separate materials with qualified fineness in advance, reduce the amount of slurry entering the ball mill (which already contains some qualified particle size grades), and at the same time reduce over-grinding of the ore, so that It not only achieves the purpose of energy saving and consumption reduction, but also avoids the possible impact of over-grinding of ore on the subsequent sorting process.

When the grinding particle size is too coarse and does not meet the grinding fineness requirements of the ore dressing ball mill, the reasons should be found from these three aspects.

1. The ball mill discharges coarse ore, indicating that there is too much ore or the concentration is inappropriate. In this case, the ore feed should be reduced or the concentration should be adjusted;

2. The graded overflow concentration may not be well controlled. Usually, the higher the concentration, the smaller the fineness; the lower the concentration, the greater the fineness;

3. The overflow weir of the classifier can also affect the grinding fineness of the ore dressing ball mill. If the overflow weir of the classifier is high, the classification area will be large and the product will be fine; if the overflow weir is low, the classification area will be small and the product will be coarse.

In addition, accurate steel ball diameter and scientific ball loading and replenishment are also effective ways to improve the crushing probability of minerals and medium energy, thereby improving the mill productivity and playing a positive role in achieving the grinding fineness requirements of the mineral processing ball mill. effect. At the same time, due to the reduction in the sliding power consumption of the grinding medium, the power consumption of the mill is also reduced, achieving energy saving and consumption reduction of the ball mill, and obtaining significant economic benefits. Media consumption also has the dual effect of being reduced. This also proves the widespread maturity, reliability and practicality of mining ball mills in energy saving and consumption reduction applications in mineral processing plants.
