Grinding ABB

Grinding is a significant and critical part of the ore winning process. On average, milling is the process that requires the most energy in the whole mining operation. To ensure profitable operations, an efficient grinding circuit has to be designed, especially now, where global mineral resources are decreasing and the exploitation of low-grade deposits become necessary.

Machine learning solves grinding mill liner ­monitoring ABB

17/09/2019 Venkat Nadipuram ABB Process Industries, Mining, Aluminium and Cement Baden-Daettwil, Switzerland, carry out the physical grinding process. As the drum rotates, the ore/balls are lifted up the side of the drum’s interior by vanes to the cascading angle, where they fall off and crash to the bottom, reducing the ore. As drum diameters can be as large as 10 m, the drum is an expensive
