TheBond Rod Mill Work Indexis a measure of the resistance of the material to grinding in arod mill. It can be used to determine the grinding power required for a given throughput of material underrod mill grindingconditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
[email protected]The lowenergy crushing work indexlaboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impactwork index)). Therod mill work indexlaboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original …

Rod mill work index is used in the SAGMILLING.COM Bond/Barratt specific energy consumption model. The work index is used to calculate the energy requirement to grind rocks in the medium size range, from10 mm - 20 mmdown to about 2 mm.
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 of20kg of -12.5mm material. Closing screen sizes typically range from4.75mm to 212µm.
TheBond rod-mill work indexis used in conjunction withBond’s third theory of comminution to merely calculate net energy requirements for sizingrod-mills. This test was originally developed in the mid 1930s by F.C.Bond. Though, it was altered in succeeding years, it …
Bond Rod Mill Grindability Test. The test determines theBond Rod Mill Work Indexwhich is used with Bond’s Third Theory of Comminution to calculate net power requirements whensizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standardrod mill.
TheBond Ball Mill Work Indexis a measure of the resistance of the material to grinding in aball mill. It can be used to determine the grinding power required for a given throughput of material underball mill grindingconditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
The Bond Index conforming rod charge consists of:6 rods of 1.25“ diameter and 21“ length 2 rods of 1.75“ diameter and 21“ length The grinding jar for the Bond Index Rod Mill is12″ x 24″in size and has a wave-shaped design.
The Titan Bond Work Index Rod Mill is one-piece cast construction with integral wave liners of a form described by Bond. This mill is used to perform the necessary metallurgical testing to determine the grinding characteristics of ores and power requirements for operating production-size rod mills.

TheBond rod mill work indexis not as common as theBondballmill work index, and there are two different variations on themillapparatus.The SAGMILLING.COM models expect amillwith a "wave liner", and is not compatible withmillsusing "smooth liners".
The grinding jar for theBond Index Rod Millis 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 orrod mill. TheRod Mill Work Index(RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas BallMill Work...

To calculateBond rod-mill workindices, the four samples were screened and the particle size distributions plotted in Fig. 2.The plot was used to find F 80 of the samples for calculations. Fig. 3, Fig. 4 show the grinding kinetics of Pb, Cu, Fe, and Mn ores in theBond rod-millin different test-sieves. The slopes of all lines in the figures are equal to the k value of Eq.
