Grinding mill inspections

Issues that go undetected can lead to breakdowns and unplanned downtime, significantly increasing repair costs and production losses. Metso offers three standardized inspections for your grinding mill so that you can catch problems early.
 
  • Mill visuals and vitals: Aimed at improving mill reliability, this inspection focuses on catching cracks, oil contamination, and slurry leaks with minimal downtime.
  • Mill mechanical verification: Aimed at improving mill integrity, this inspection looks for wash under trunnion liners and includes mechanical adjustments and critical torque verifications.
  • Mill comprehensive/customized: Aimed at improving mill longevity, this inspection includes an in-depth analysis of the gear and pinion as well as retrofit designs and procedures, as required.

Process optimization and controls for grinding mills

The comminution circuit has many different elements and interactions that can make it challenging to choose the correct operating and control strategies. Metso provides numerous services and tools to aid in optimizing the comminution circuit in order to increase throughput, availability, or reduce energy consumption.
 
Metso grinding equipment and process specialists use ore characterization data, comprehensive plant surveys, and historical operational data to develop site specific models for your comminution processes. These models are used in simulation studies along with extensive industrial and consulting experience and our benchmarking database to assess your comminution processes. We evaluate circuit configuration, operational parameters and the key design variables to identify areas for improvement in the comminution process.
