Dry Grinding VSWetGrinding. It appears, however, that the rate ofballand liner wear is greater inwet millingso the decision betweenwetand dry operation is, in cases where the choice is permitted, a matter of balancing the economic gain arising from reducedpowerdemand and increased throughput against the increased cost of replacement of theballcharge and themill....

Impact and attrition size-reductionmethodsinclude air classifyingmills, pinmills, hammermillsand jetmills. Shear, impact and compressionmethodsare used in media orball mills. The five types ofmillingtechnologies discussed in this article cover more than 90 percent of size-reduction applications in major chemical, food ...

The maximumpower drawinball millis whenballbed is 35-40 % by volume in whole emptymillvolume. Considering thatballbed has a porosity of 40 %, the actualballvolume is considered to be ...

Working Principle & Operation. The apparent difference in capacities between grindingmills(listed as being the same size) is due to the fact that there is no uniformmethodof designating the size of amill, for example: a 5′ x 5′Ball Millhas a working diameter of 5′ inside the liners and has 20 per cent more capacity than all otherball millsdesignated as 5′ x 5′ where the ...

Ball millswork well with brittle, hard materials, and canmilland blend materials at the same time. They are not suitable for elastic, fibrous, or ductile materials.Ball millscan be very large, 5-6 m in dam, and even larger with inputpowerup to 20 megawatts. The largestmillsare used in mining operations. AttritorMills

Maximumpoweris drawn by amillwhen the charge occupies approximately 50% by volume. Thepowercurve becomes very flat in the range above 45%. As a result,millsare seldom run with charge levels greater than 45%. In rodmills, the charge is swollen by particles of feed which separate the rods. If themillis shut down immediately after the feed is shut off, the charge level will be greater ...

Thepower drawof themillis then obtained by multiplying KWr by the tons of rods in themill, which yields: KW = (πD²/4 L V pρ)(1.07 D.34 (6.3-5.4 Vp ))Cs………………………………………………….(3) KW =mill power drawat the pinion shaft, kilowatts. p = rod charge bulk density, tons per cubic foot.
