bond rod mill work modified

Therod mill workindex laboratory 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 and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining therod mill workindex ...

*BondF. C., “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 58-66.Bond Rod MillGrindability Test. The test determines theBond Rod Mill WorkIndex which is used withBond’s Third Theory of Comminution to calculate net power requirements when sizing ballmills*. Various correction factors may have to be applied.

3.4.7Bond rod millstandard test. Standard conditions for determining theworkindex ofrod millsunder laboratory conditions are:millsize = 305 mm (internal diameter) × 610 mm (internal length) with wave type lining. material dry mineral. size − reduced to 100% < 13,200 μm.

TheBondIndex conformingrodcharge consists of: 6rodsof 1.25“ diameter and 21“ length; 2rodsof 1.75“ diameter and 21“ length; The grinding jar for theBondIndexRod 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.

Rod millsnormally carry 35 to 65%rodcharge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into themill, and (2) keeping therodcharge low sorodswill notworktheir way into discharge openings where they can causerodtangling.

Bond Rod MillGrindability Test. Grinding Solutions can carry outBond Rod Mill WorkIndex tests to determine the energy requirements for milling ore in arod mill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212µm. Abrasion Index Test

TheBondballmill workindex is one of the most commonly used grindability tests in mining, and is often referred to as theBond workindex.. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed.

Bond Rod MillGrindability: requires 25 kg of minus ½ in. material: $950. This test determines theBond Rod Mill WorkIndex, which can be used withBond’s Third Theory of Comminution to calculate net power requirements of sizingrod mills. The test is a closed-circuit, dry grindability test, is run in a standardrod mill, and can be ...

Generally,Bond workindex 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, fas ...
