This test determines the Bond Rod Mill Work Index, which can be used with Bonds Third Theory of Comminution to calculate net power requirements of sizing rod mills. The test is a closedcircuit, dry grindability test, is run in a standard rod mill, and can be performed at
The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.
Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bonds 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.

Bond Work Index Tests Grinding Solutions Ltd. 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 212m Abrasion Index Test The Abrasion Index is a recognised procedure to quantify abrasiveness and approximate
#0183;#32;The Bond rodmill work index is used in conjunction with Bonds third theory of comminution to merely calculate net energy requirements for sizing rodmills. This test was originally developed in the mid 1930s by Bond. Though, it was altered in succeeding years, it has essentially remained unchanged since 1961.
The standard bond rod mill work index test procedure is firstly to stage crush the feed to pass 127 mm and size a representative sample the test then involves a series of batch grinds in a standard bond rod mill a bond rod mill is 0305m by 0610m with wave liners of a form described by bond which runs at 40rpm and tilts as described below Jaw
The Bond Index conforming rod charge consists of: 6 rods of diameter and 21 length; 2 rods of 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.
The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing mm (#189; 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 ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a ''lockedcycle'' test where ground product is removed from test cycles and replaced by fresh feed.
Jul 30, 2020#0183;#32;Measuring ore grindability in rod mills. The Bond Rod Mill Work Index is a measure of the resistance of the material to grinding in a rod mill. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions. It is a ''locked cycle'' test conducted in closed circuit with a laboratory
Bond Test WIs (kWh/t): Rod Mill: Ball Mill: kWh/ 9 kWh/t . Bond Standard Circuit Work Index: Assume the rod mill Work Index of applies from the actual rod mill feed sizeof 19,300 m#181; (although some of this work might ideally be done by crushers to achieve a rod mill F80 of 16,000 m) to a rod #181;
Generally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research, a simple, fast and accurate procedure is introduced to find the
