Apr 07, 2018 EF6 will not apply as ratio of reduction will be within Rro ±2. Rro determined after mill size selection. EF7 does not apply. EF8 The rod mill feed will be prepared by closed circuit crushing and the rod mill will be in a rod mill-ball mill (or pebble mill) circuit with no intermediate concentration stage so no EF8 factor need be applied.

Gabor Takacs PhD, in Sucker-Rod Pumping Handbook, 2015. 3.8 Gear Reducers. Speed or, more commonly, gear reducers (gearboxes in short) are the heart of the pumping unit and represent about 50% of the investment cost of any pumping unit. Their main function is to reduce the high rotational speed of the prime mover to the pumping speed required and, at the same time, to increase the output ...

Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

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). Grinding action is by line contact between the rods extending the length of the mill.
