The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill WorkDETERMINATION OF THE BOND’S WORK INDEX OF BABAN ,grinding the reference and test ore with the same particle size distribution under the same grinding conditions. Typical feed load and mill speed in practice were used in order to make the grinding environment as close as possible to that in large scale grinding. The Bond’s work index of Baban Tsauni (Nigeria) ore was found to be 11.52kWh/tonne.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().Bond Tests Mining SGS,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.
