Large Ball Mill Scale Up Factors To Be Studied Relative To

may 01, 1984 ball mills 5.5 in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. this paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.the grinding media cost was reduced by the equivalent of 200,000 usdyear by switching to a lower cost duromax cast grinding ball. the customer indicated that should the plant suffer a loss in copper recovery they would revert to the initial alloy.the subject of this case study is the nde pinion bearing of ball mill No in the mill dpt. in the flotation plant. the bearings on the pinion are of type mb. spm HD spectrum from the nde bearing shows a clear match of the bpfo symptom. according to the customer, following the indications for bearing damage from condmaster ruby they replaced the pinion shaft, where they found visible signs of outer race damage on the nde abb in mining delivers complete plant electrification, integrated process control and optimization solutions, motors and drives systems as well as instrumentation and analyzer systems.
