Rolling Bearings and Services for Mining and Processing

Vertical shaft drilling machines are primarily used for production and ventilation shafts and the extraction of ore, but also for installing rescue shafts. When the huge drills start running, it is important for every single machine component to be able to withstand the harsh conditions of under-ground mining.


Industrial Vertical Stirred Mills Screw Liner Wear ... - MDPI

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
