After a long period of operation of the ball mill, transmission parts motor, reducer, pinion bearing bolt loose sometimes occur, transmission components displaced, so that the axis is not in the same line, thus vibration. Parking on the mill drive system should detect and re-alignment transmission.
So we have taken vibration at the motor feet, sole plate and foundations.The vibration is considerably less on the motor feet- under 1mm/secrms Now the bearing vibration on this Ball Mill is 1.8mm/sec NDE and .9mm drive end. In addition there are 2 additional sole plate holding down bolts between the the motor holding down bolts.
ball mill. After that the measurement of accelerations of vibration at housings of bearings has been performed. Due to the production requirements the capacity of the ball mill is variable and therefore the torque on the ball mill drive is also variable. Measurement has been done for two different capacities.

When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less.

vibration. A small relative motion between balls and raceway occurs in non-rotating ball bearings that are subject to external vibration. When the bearing isn't turning, an oil film cannot be formed to prevent ~rina~ ~mks raceway wear. Wear debris oxidizes and accelerates the wear process. Correct by isolating bearings from external vibration, and

•Additional vibration data was collected from the motor & gearbox of the 1A Ball Mill Drive under no load. •To determine what problems (if any) existed with the drive, a comparison of the route vibration data between 1A & 1B Ball Mills was made as well as between loaded & unloaded data at 1A Ball Mill.
Vibration Roller bearings are easily damaged from vibration when the motor is not running, so the rotor is locked during transportation. Ball bearings can sustain more vibration than roller bearings when not running. Both types can only withstand single and infrequent shocks of 2-3g without sustaining damage; shocks of greater magni-
