Based on the nth order grinding kinetic equation and the theory of linear additivity in the grinding process, the grinding kinetic characteristics of the feed and the circulating load in standard Bond rod-mill grindability tests are studied. A new method of simulating the calculation of the Bond rod-mill work index by using the grinding kinetic test data of the feed is proposed.

A Bond rod mill work index test (BRMWI) is a standard test for determining the rod mill work index of an ore sample [21]. The BRMWI is a measure of the resistance of the material to crushing and grinding in a rod mill and is used to calculate the grinding power needed for a given material parcel regarding rod mill grinding conditions.

rod mill work index has not been de ned as yet. The ball ﬁ mill work index is con rmed at 16 kWh/t. The operating ﬁ work index, though, is in the range of 21 kWh/t to 25 kWh/t showing high inefﬁ ciency. This raises the point that, in some cases, the Bond EF4

For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball

Testwork: Bond Rod Mill Work Index. The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus.
