For example if the particle size and the uniformity of the crusher directly affect the quality of the ball mill feed and the relatively good material enters the ball mill the time and power consumption required for grinding will be reduced so that it can be said it improves the working efficiency of the ball
Grinding mill medium is the main factor affecting grinding efficiency in industrial production the type shape size ratio and filling rate of grinding medium should be determined according to the grain size characteristics hardness characteristics and product particle size requirements of ore
High classifying efficiency means that those qualified grains can be discharged timely and efficientlywhile low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for regrinding which is easy to cause overgrinding and thus affecting
In ball mills all the media is balls with a high sg so the impact of pooling is not as large additionally in ball mills grinding is primarily through cascading not cataracting compared to an agsag so the slurry pool is not a factor unless density is high which leads to viscosity
