Energy consumption and pollution are current strategic issues that need to be addressed in the mining industry. Both have an economic and environmental impact on production, so their optimization, control, and mitigation are, at the very least, mandatory. Although rod milling has fallen into disuse in recent decades, some companies still use it in their processing plants. This is due to the ...

Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.

Tubular Rod Mills. In Mineral Processing Design and Operations (Second Edition), 2016. Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of %. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

Fine crushing and rod grinding have been investigated using a laboratoryscale jaw crusher and a rod mill. The net energy consumption in both crushing and grinding was evaluated from torque measurements. An empirical relationship was established between energy consumption, particle size and operating parameters. When the mill feed size is reduced, through fine crushing, to about 80% passing 3 ...

The rod mill will limit you to around 800 um. I speculate with the blue line in graph below. The grate ball mill is likely halfway in between an overflow ball mill and a rod mill. As much as I like rod mills, in your situation, I would go with a ball mill (for ease of operation). Be sure to have good classifier efficiency and you are in the clear.
