Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

The X screw is about 53 inches long and 1-3/16 in diameter, with a 4 or 5 pitch. I seem to recall reading that you can calculate the precise ball size needed based on the pitch diameter and the measured backlash. I could model this simply in a CAD program, however the gothic arch ogive data is the gotcha I don''t have.

When we hang Cosmo by the bungee cord, letting him come to rest, we find that the stretched length of the bungee cord is 1.25 m, an increase of x = 0.73 m (see figure below). We calculate the spring constant of the bungee cord: k = F/x = mg/x = 15.2 N/m.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

To put real numbers on this, that would be equavalent to a .012, .025, and .042″ stepover for a .125″ ball mill. Stepover =1/10 of diameter. Stepover =1/5 of diameter. Stepover =1/3 of diameter. As you can see, the change in quality is so dramatic that you might be tempted to always use the smallest stepover possible.

A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. The term “circulating load” is defined as the tonnage of sand that returns to the ball mill, and the “circulating load ratio” is the

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
