  1. BALL MILL PLANTS — MAINTENANCE AND CARE A guide to monitoring, diagnosing and rectifying ball mill plants to ensure their long life.

  2. The Need of Regular Inspections • Regular inspections guarantee trouble-free and optimal operation of the machinery involved. • Inspections catch anomalies, thereby eliminating major break-down of machinery. • Inspections allow us to identify out-dated process chains and replace them with more advanced technologies. • Periodic checks for wear and tear are essential to maintain high (and reliable) levels of output. Property of Chanderpur Group.

  3. The Stages of Inspection The slide shoe bearing ball mill is especially prone to wear-and-tear. This type of mill requires clockwork inspection. “ • 1. Preliminary Examination (when the machine is at standstill) • 2. Inspection of the Separator • 3. Detailed Inspection of the Gear • 4. Data Compilation, Final Report, and Recommendations Property of Chanderpur Group.

  4. 1. Standstill Inspection • External and Internal inspection of the machinery by experts • Checking for hydraulics and lubrications • Checking to see if the internals of the ball mill show any sign of cracks • Measuring the tolerance level between the Slide ring and Slide shoe. Property of Chanderpur Group.

  5. 2. Inspection of Separator The Separator is checked for faults in the following: • Physical damage • Internal rotor • Guide vanes • Output quality check • General calibration and oiling Property of Chanderpur Group.

  6. 3. Inspection of the Gear Specialized vibration measurement tools are used as the Gear is checked for the following: • Accurate overview of overall functioning • Measuring temperature variation of the gears during full run • Testing back-lash created to ensure that the gear is not generating any undue vibrations Property of Chanderpur Group.

  7. 4. Data Compilation and Evaluation All the data collected during the evaluation of the machinery is compiled and conclusions are drawn based on empirical evidence. A comprehensive inspection of the gears is followed by an equally detailed report highlighting the main areas of concern, and the steps that can be taken to correct them. Property of Chanderpur Group.
