Agenda
An overview of AG, SAG, rod and ball mills and their capabilities followed by a detailed exploration of the typical components that make up horizontal mills with a special focus on main bearings, main bearing lubrication systems and mill drives. Includes a review of site-specific piping and instrumentation diagrams for main bearing lubrication system(s) of Metso origin when available.
A discussion of physical stresses that affect horizontal grinding mills during operation and how to recognize and mitigate them.
An outline of typical planning, preparation and procedures involved in performing maintenance safely and efficiently including instruction on safely positioning horizontal grinding mills for maintenance using an inching drive.
An inclusive checklist of data points that should be tracked constantly or daily while a mill is running, where the gauges that record or transmit operational data are located and manual options for obtaining operational data if transmitters are not installed.
An in-depth examination of lubricant properties, contamination hazards, sampling procedures and testing recommendations for both circulating oil and gear spray lubricants.
An overview of vibration principles, data collection equipment, the data collection process and how vibration data is interpreted.
A comprehensive review of the preventive maintenance tasks that should be performed at regular intervals – from daily to annually – in order to keep a mill running in top condition. Tasks are divided into those that can be performed while the mill is in operation and those that require the mill to be shut down. Recommendations for spare parts storage are also included.
