Vertical roller mills and ball mills are regularly taken out of operation for routine maintenance. Some plants even shut their mills down every week. Yet, gearbox inspections are typically scheduled for the annual maintenance shutdown when resources are stretched. This is making life harder than it needs to be for all involved.

The ball mill is equipped with a general electrical control cabinet for process control. The control system is based on a Siemens or Rockwell PLC, developed to control the working conditions within a minimum range of variation, in order to assure a constant level of quantity and quality of the oxide produced.
