How to choose the best ball mill ball load?
In the design of ball mill, we must choose the appropriate wear-resistant materials, and to determine the appropriate starting Ore Milling Equipment ball load and run the amount of additional grinding ball, which reduce metal consumption, improve economic efficiency has great practical significance. So how to choose the best ball mill ball load? The test shows that the power consumption of the ball mill in the case of the material and no material difference of only 5 to 8%, that is, most of the power required to mill the ball mill and the barrel itself rotating, for a ball mill and Say, cylinder rotation energy consumed is certain. Therefore, a reasonable choice of the optimal ball load, to reduce coal consumption, it becomes a key issue. Ball mill ball load is filled by the ball filled with coefficients to reflect. Ball loading increases, the ball mill output also increases, when the ball load exceeds a certain amount, the ball mill output slowed down, while the milling system power consumption has increased significantly. At this time due to increase the output of the ball mill benefit and milling power consumption caused by increased consumption compared to the high, obviously not worth the candle. Therefore, the ball load must be appropriate, the load is too large, the milling power consumption increases; load is too small, the ball mill output is insufficient. The amount of ball mill grinding ball selection, should be based on the test to find out the greater output of coal mill, milling power consumption when the minimum load. Grinding ball load at this time, that is, the ball mill best ball loading capacity. The ball mill ball filled with a coefficient of 0.2 to 0.35, the more appropriate ball filled coefficient should be selected between 0.18 ~ 0.25.
