Comparing Ball and Vertical Mill Performance

2018-2-20  Thankfully, the performance of the vertical mill was still better than the ball mills, which reinforces the use of this technology. But the use of scrap compromised the registration of media addition to the vertical mill making the control of media consumption impossible for a long period. Only by the beginning of 2013 this register was normalized.
