The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh)

in Figure 1) represents the degrees of rod reversal referenced in API-618 (paragraph 6.6.4)2. Had 3500/S1 been configured to calculate rod load at the piston rod, the inertia forces would no longer include the crosshead mass. The combination of this inertia force and gas force results in the forces that act on the piston rod, next to the crosshead

Sep 22, 2018 Specific Speed of Pump. The specific speed “Nq” is a parameter derived from a dimensional analysis which allows a comparison of impellers of various pump sizes even when their operating similar Q -H range.. The specific speed can be used to classify the optimum impeller design. Specific Speed of pump (Nq) is defined as the speed in RPM at which a geometrically similar impeller
