2. Pitting This is a major cause of gear failure accounting for nearly 60 of the gear failures. Pitting is the formation of craters on the gear tooth surface. These craters are formed due to the high amount of compressive contact stresses in the gear surface occurring during transmission of the torque or in simple terms due to compressive fatigue on the gear tooth surface.

Ball Mill Motor Failure Root Cause Investigation Seth Kahle 2019-05 Project Description. The grinding operation at PVM has only 6 total primary ball mills. After several years of running without electrical issues the ball mill motors began failing. create preventative maintenance tasks for clutch maintenance inching mills that went

Planetary Ball Mills are used wherever the highest degree of fineness is required addition to well-proven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor gearbox and both pinion bearings. The recommendations for repairs was

We will begin with the mill s bull gear assembly and work towards the motor The BULL GEAR sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills Rod Mills and SAG Mills. Anything gear and pinion really. The discharge end of the mill For the operator this only becomes a problem should the

Ball mills on the other hand as far as process requirements are "Lessons learnt from recent failures of gear drives on mills in • Synchronous motors provide not sufficient torque to start the mill directly coupled • Clutch system required which leads to higher maintenance .

The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill. The torque and time requirements of the mill with the ball

cated by the fact that one failure mode may initiate another. For example corrosion in a ball race leaves rust-an abrasive-which can cause wear resulting in loss of preload or an increase in radial clearance. he wear debris can in a grease-lubricated bearing impede lubrication. resulting in lubrication failure and subsequent overheating.

These are the biggest ball mills yet supplied for a platinum mining industry application in South Africa and are also among the biggest anywhere in the world. With each ball mill drum having a monumental total inertia of 14 195 400 kgm2 controlling the drums (i.e. stopping holding and positioning them) presented its own unique problems.

One of China s largest chemical/fertilizer producers was experiencing unusually high failure rates of the clutches installed on three ball mills at its processing facility. The clutch s friction discs needed to be replaced every six months which was a very costly and labor intensive problem. Read More
