Industrial Vertical Stirred Mills Screw Liner Wear Profile Compared to Discrete Element Method Simulations

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency comparison with conventional tumbling mills. In this context, agitator liner wear plays an important role maintenance planning and operational costs. paper, we use discrete element method (DEM) simulation evaluate screw wear. Three different mill rotational velocities are evaluated simulation, according scale-up procedures. The profile, measurement, power consumption, particle contact information used for obtaining a better understanding of behavior effects on grinding mechanisms. Data from vertical measurement obtained full-scale correlate results. results indicate relative agreement industrial most lifecycle, when using proper velocity scale-up.
