As such you will find it is designed and constructed according to heavy duty specifications.
Due to the action of the inertia and the friction force, the steel ball and the material in the mill bin are started to form a steel ball, and the material falls back to impact the cylinder body so as to generate periodic vibration. After the mill is running for a certain period of time, it is affected by its own vibration.
Compact mill arrangement reduces foundation vibration risk When you install the MAAG® LGDX side drive at 40° below the ball mill, you not only save money and time due to the low foundation height, you also minimise the risk of vibration issues – increasing the reliability your ball mill.
Pulverizing Ball Mill Failures Smart Lubrication Management and Oil Analysis Deliver Uptime and Reduced Costs. ... Gearbox reliability on the pulverizers has historically been poor.

Lubricant-related failures can be avoided by selecting a grease or oil that generates a sufficient film to keep bearing elements separated. A good lubricant also provides good boundary lubrication. Lubricant failures can be detected by the presence of discolored (blue/brown) raceways and rolling elements.
They are known as Ball, Rod, Tube, Pebble or Grinding Mills, The pinion gear normally varies from 1-1/2 to 2-1/2 feet in diameter And, worn pinions due to misalignment, pinion bearing failure and, sometimes, break-, The lubricant cannot overcome weak foundations, poor gear alignment, undetected vibrations, poor.
