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.

The Simple-Nut Ball Screw is an offset preload type in which a phase is provided in the middle of a single ball screw nut, and an axial clearance is set at a below-zero value (under a preload). The Simple-Nut Ball Screw has a more compact structure and allows smoother motion than the con-ventional double-nut type (spacer inserted between two nuts).

capacity (0.6×Fy) of the diameter of rod used. A 1/2"diameter anchor bolt has the following capacity: (0.6×36,000psi)×(π × 0.52/4) = 4,240 psi, as noted in the Table. The capacity of any substituted grade of steel can easily be calcu-lated if the yield point and diameter are known.

The Ball Screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion. Therefore, it is capable of an accurate micro feeding. Fig.4 shows a travel distance of the Ball Screw in one-pulse, 0.1-μm feeding. (LM Guide is used for
