The ratio of the trunnion thickness to trunnion diameter in a mill of 2,134 m diameter is almost twice that of a mill of 5,8 m diameter, i.e. a ratio (T/D) of 0,116 to 0,069 for the large mill. However the design stress levels at the trunnion/head transition in the case of the large mill are almost 250% of those in the small mill. Read More

material to reach ideal particle size distribution, the hammer mill would simply be placed at the beginning of the process. In the diagram, you can see that at the screening point, on-size material is separated out, under-size product goes back to the beginning of the process, and over-size product goes through size reduction before it is ...

The usual speed reduction ratio of pumping unit gearboxes is about 30 to 1, the maximum output speed is around 20 SPM. Speed reducer sizes are standardized by the API in Spec. 11E [111]; the rating relates to the maximum mechanical torque allowed on the reducer.

Reduction ratio = 2 - 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% - 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3. In wet grinding, the solids concentration 1s typically 60% - 75% by mass.

These mills are required to prepare ball mill feed. With pebble milling the pebble portion of the product does not go thru the rod mill thus the rod mill feed rate is reduced by 30 metric tonnes per hour (6% of 500 metric tonnes per hour). 2062/500 x 470 = 1938 HP 1938 ÷ 2 = 962 HP

The mill can achieve a size-reduction ratio (the ratio of feed particle size to final product particle size) as high as 40-to-1 in one processing pass. The cage mill's high size-reduction ratio results from its crushing mechanism: impact rather than compression.

Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp Speed reducer efficiency: 98% 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power). Therefore select a mill to draw at least 5440 Hp at the pinionshaft. Based upon the pilot plant test results, the volumetric loading for the mill can be determined.
