bond rod mill index test
Comminution. This test determines the Bond Rod Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements of sizing rod mills The test is a closed-circuit, dry grindability test, is run in a standard rod mill, and can be performed at sizes ranging from 476 mm to 210 microns.
