  • Ball Mill Girth Gear and Pinion AlignmentCR4 Discussion

    Aug 28 2011 · Re Ball Mill Girth Gear and Pinion Alignment 08/27/2011 2 07 AM pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum the grease marks will show the contact area. the pinion should contact the girth "ring" near the center of the gears. This investigation attempts to obtain a better understanding of flow behavior of a pigmented dispersion in a ball mill. A power-law fluid model was used to approximate the rheological behavior of the milled fluid. To cor­relate power data on each of 276 milled dispersions this model was used together with power number Reynolds number Froude number and some geometrical variables.

  • THE OPTIMAL BALL DIAMETER IN A MILL

    The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter ball mill loading milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1. A new Geoscience centrifugal ball mill was used to mill various batches of 238 PU02 for varying time intervals. To attain simi-lar particle size reductions with this mill shorter milling times were anticipated be-cause of higher rate of energy input. Mill-ing was carried out using a carrier liquid which was expected to reduce agglomeration.
