How to Judge the ball mill steel balls percentage are proper
1. The amount of ore feed and the overflow fineness of the classifier remain unchanged, while the amount of returned sand decreases, which means that the grinding effect of the ball mill is strengthened, and the ore feed can be increased at this time.
2. According to the sieve analysis results of the returned sand from the classifier, it is found that the ore particles close to the overflow particle size increase, which indicates that the number of small balls is insufficient; on the contrary, if the coarse particles increase, it indicates that the number of large balls is insufficient.
