Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here. Within these test works, mill parameters like grinding pressure, separator speed and dam ...

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).

Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, lesscoarse medium.
