15-5PH Bar. 15-5 stainless steel is a martensitic, precipitation-hardening material with chromium, nickel and copper. It is often a first choice in the aerospace industry for fasteners and structural components. Its unique structure provides increased toughness and better corrosion resistance than its predecessor, 17-4 PH.
The bulk density of a new rod charge is about 6.25 t/m 3. With time due to wear the bulk density drops. The larger the mill diameter the greater is the lowering of the bulk density. For example, the bulk density of worn rods after a specific time of grinding would be 5.8 t/m 3 for a 0.91 m diameter mill.

Therefore, increase ...
Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

The density is expressed in pounds per unit of volume, and the density of ductile iron is .255 lbs. per cubic inch. In the above example, the volume is 70.7 cubic inches, therefore, the bar weighs: 0.255 x 70.7 in3 = 18.0285 lbs. If the bar were made out of steel having a density of 0.284 pounds per cubic inch, the bar would weigh:
