Specifications veichi ac70 q is a special ac frequency inverter designed for ball milling machine that it is widely used in ceramic industry using ac70q it will bring you great benefits both in economy and environment such as decreasing energy cost reducing maintenance cost of your machine and cutting down carbon dioxide emissions 1
In most cases the ideal mill speed will have the media tumbling from the top of the pile the shoulder to the bottom the toe with many impacts along the way the ideal mill speed is usually somewhere between 55 to 75 of critical speed
The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in sag mills the increased frequency is due to the increase in charge volume 35 40 versus 5 10 higher mill speeds and the larger number of balls per unit charge weight
