Requirements for the diameter of the steel balls loaded into the ball mill. The output of the ball mill is not only affected by the loading of the steel balls, but also related to the diameter of the steel balls. It is required to have a certain ball diameter and maintain a certain proportional relationship between balls with different ball diameters. Generally, the size range of the ball diameter in the cylinder is. If the cylinder is full of large-diameter balls, the impact force will be greater, which is beneficial to crushing large pieces of coal. However, due to the large gap between the balls and the small relative surface area, the squeezing and grinding effects will be weakened, which will be detrimental to the coal mill. The output and coal fineness are both unfavorable. There are too many small-diameter steel balls in the cylinder and the impact force is small, which will reduce the output of the coal mill. At the same time, due to the relative increase in the surface area of the steel balls, the wear of the steel balls will increase, and the power consumption of coal grinding will increase.
For example, during the operation of the coal mill, the weight and diameter of the steel balls are constantly decreasing due to wear and tear, so new balls need to be added regularly to maintain a certain loading capacity of the steel balls. Generally, large-diameter balls are replenished, and the amount of replenishing balls should be determined based on the steel ball wear rate (the amount of steel ball wear per ton of coal ground) and the amount of coal grinding. After the coal mill has been running for a certain period of time, the number of small-diameter steel balls in the cylinder increases. Therefore, generally after about an hour of operation, the machine needs to be shut down to clean the steel balls in order to remove balls smaller than the diameter and broken balls, and to make up for new balls at the same time.
