The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as …

To separate the mill dust from the ball mill media, put a round 20-mesh screen into the mouth of a bucket that is the right size to hold it. A screen-type colander that is about 20-mesh works, too. The screen should be firmly attached to the frame of the colander. Carefully open the ball mill jar and gently pour its contents into the screen.

Since we have a common factor other than one between the two gears on the ball mill we can expect to see the appearance of fractional gearmesh frequency and harmonics in our vibration data. In this case since the common factor is 2, we expect to see the appearance of 1/2x gearmesh and harmonics in our vibration data.
