Get Price· 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 close to exactly the same for both drives.
Get PriceDec 31, 1995 · The balls' diameters were as small as 12 mm in the smaller mills and as large as 30 mm or more in the bigger mills. The vibration was made by rotation of the unbalanced shaft, combined with the action of the springs at high speed. The small laboratory mill which was the most popular size had liter capacity.

Get PriceThe trait of the ball mill is chaotic in nature due its complex dynamics associated during grinding. Grinding in ball mill generates highintensity vibration and is too complex on account dependency of multiple variables. In this paper, the vibration signal is acquired using a low power ZigBee based three axes wireless MEMS accelerometer sensor mounted onto the mill shell.
Get PriceMill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product .
