Mill power for conical (Hardinge) type ball mills - ScienceDirect
1992.1.1 It has been found that a change in density of 2.6 to 2.9 (an increase of density of 11.5%) gives a 1.5% increase in mill power for these conical mills, for Pb = 7.75. Inserting p51 = 2.6, Pb = 7.75 and solving for fc gives 0.445, and using the estimate for c, f ~ 1.0. Thus it appears that the powder in the mill is circulating in about the same ...

2023.5.2 Figure 2.27. Cut-away view of the Hardinge conical ball mill showing how energy is proportioned to the work required is about 0.3 kg/Mg of material for dry grinding, and 1-1.5 kg/Mg for wet grinding. The normal charge of balls is about 5 Mg/m3. In small mills where very fine grinding is required, pebbles are often used in place of balls.

Bridgeport Boss 3 X-axis ballscrew
2022.12.29 Re: Bridgeport Boss 3 X-axis ballscrew. That's a good-looking machine. Mine looks to be in fairly nice shape, it's just the X axis ball screw that shows that much wear (It actually has .008" of backlash, but I rounded up). The Y Ball screw shows barely any backlash at all, definitely less than .001".
