Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.

The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30% higher than the energy consumed by bar mills and this is for comparable performance.
Next, we will introduce the role of the vertical mill in the EPC production line. 1. grinding effect.
