including an increased mill motor rpm and elevated recir-
culation rate.
This observation underscores the model’s capability to
discern conditions contributing to heightened wear, provid-
ing valuable insights into operational scenarios associated
with increased media loss. The graphs serve as a tangible
manifestation of the outcomes yielded by the developed
mathematical approach, offering a concise and illustrative
summary of the predicted mass loss trends for the respec-
tive motion phases.
CONCLUSION
The applied mathematical computational approach has
proven instrumental which provide intricate insights into
the real-time media wear rate induced by the cascading and
catracting actions within the grinding mill along with oper-
ational parameters. Furthermore, the implemented model
serves as a proactive tool, signalling optimal moments for
media replenishment. This is achieved by triggering alarms
precisely when the volumetric filling of media in the mill
approaches its upper control limit (UCL) and lower con-
trol limit (LCL). By dynamically regulating media quanti-
ties (as to p media size 70 mm), the model ensures that
the volumetric filling remains within the prescribed limits,
contributing to enhanced operational efficiency and pro-
longing the effective lifespan of the grinding media.
