The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80 passing 127 mm ½ inch the original test being developed in imperial units to a product size of approximately 1 mm in the original and still the standard 14 mesh see Chapter 4 for definition of mesh thus determining the rod mill work index

The Bond Index conforming rod charge consists of 6 rods of 125“ diameter and 21“ length 2 rods of 175“ diameter and 21“ length The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a waveshaped design At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill

Bond Rod Mill Grindability Test Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill The test requires a minimum of 20kg of 125mm material Closing screen sizes typically range from 475mm to 212µm Abrasion Index Test

Jan 01 2013 · The Bond rodmill work index is used in conjunction with Bond’s third theory of comminution to merely calculate net energy requirements for sizing rodmills This test was originally developed in the mid 1930s by FC Bond Though it was altered in succeeding years it has essentially remained unchanged since 1961

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 closedcircuit dry grindability test performed in a standard rod mill
