It can also form a combined crushing with a ball mill. The present research is aimed at overflow VRM. For the VRM, scholars mainly consider the research of powder separation performance (Bhasker, 2002, Vuthaluru et al., 2005, Dou et al., 2011) and its application in crushing metal ore (Altun et al., 2015, Li et al., 2020, Boehm et al., 2015).

Within the scope of the study, ore grinding performance of the VRM was investigated via a mobile grinding plant and relationships between operational parameters were identified. In this context, gold ore was ground under different process conditions. The samples collected after the test works and size distributions were determined.

The main way to improve the performance of ball mills is to optimize the operating modes of the electric drive and mill equipment, to ensure stable operation of the ball mill and electric motor at ...
