How to add steel balls to the ball mill, and how to configure the steel balls?(2)

Ball mill steel ball adding skills

The ball mill steel ball ratio should be based on the effective length of your mill, whether it is equipped with a roller press, the size of the feed, what liner and structure to use, the expected sieve fineness and ratio, how many chromium balls to use, and the speed Comprehensive judgment of how many and other factors. After the ball mill is installed, the large and small gears of the ball mill need to be meshed, and the processing capacity must be gradually increased. After the ball mill runs normally for two or three days, check the meshing of the large and small gears. When everything is normal, open the manhole cover of the ball mill and add the remaining 20% steel balls for the second time.

Precautions for Ball Mill Steel Ball Classification

1. When the ball mill is operating normally, the reasonable friction between the steel ball and the steel ball, the steel ball and the ore, and the steel ball and the ball mill liner will increase the wear. Generally, there is no need to add small balls.

2. The steel balls in the ball mill are constantly worn out during operation. In order to maintain the ball load filling rate and reasonable ball ratio, and maintain the stable operation of the ball mill, reasonable ball compensation must be carried out to compensate for wear.

3. The added weight of the steel ball is determined by the quality of the steel ball, and the quality of the steel ball determines the amount of added ore per ton. Use new wear-resistant steel balls. The added amount of high-quality steel balls is calculated based on the processing volume per ton of ore (ie 0.8㎏ per ton of ore). Ordinary steel balls need to process one ton of ore (1㎏—1.2㎏).

In short, the ratio of steel balls in a ball mill is a more complicated technical issue. Each concentrator must carefully analyze its own actual situation, and through long-term research and accumulation, can it find a suitable ball loading ratio. In addition, the ratio of steel balls also includes the size and quantity of the balls. The ratio is determined based on all the information, and it must be just right.
