THE REASONS FOR THE INCREASE OF THE GRINDING

Changes to mill performance. Yes, such things do happen. Maintenance or upgrading of material supply conveyor can affect the speed and quantity of material loading to the ball mill. In the wet grinding, changing the flush density of the ball mill can significantly affect the grinding balls consumption.

Comparing ball and vertical mills performance: An

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.

The large focus is on the power consumption and increased output. The grades of H of SBIPL are such that the balls retain their shape as they tend to wear. De-shaped balls are like dead balls, which do not assist in effective grinding, and tend to slide as they move up the periphery of mill, instead of falling or toppling from the top.
