Bond Rod Mill Grindability: requires 25 kg of minus ½ in. material: $950. This test determines the Bond Rod Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements of sizing rod mills. The test is a closed-circuit, dry grindability test, is run in a standard rod mill, and can be performed at sizes ranging from 4.76 mm to 210 microns
Get PriceCommentary on the apparatus of the Bond rod mill Work Index by Alex Doll December, 2015 [email protected] The Bond "Third Theory" of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period when Bond (and his collaborators) were gathering the information to calibrate comminution models. The middle
Get PriceThis range covers crushing, DWi, Ab, rod milling and ball milling where different work index values are applied to each range to arrive at the Bond SE value. After applying the AG/SAG factor to the Bond SE value corrections are made for the SG, Ab values and low aspect (LA) mill conﬁ guration if applicable.

Get PriceTests range from industry standards, such as Bond Work Index Testing, to cutting-edge techniques such as pulp chemistry monitoring, to help optimise comminution circuits. We are also a accredited laboratory for fine grinding. We have comminution equipment including ball mills, rod mills and a range of crushing equipment. This allows Grinding Solutions to offer a unique mineral
Get PriceThe Bond's Ball-Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. This Index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill scale-up.

However, the author has developed a relationship between the Bond third theory SE values and the AG/SAG SE values to enable the additional power required for AG/SAG milling to be determined. AG/SAG inef ciency varies according to the transfer size ﬁ (T80), whereby the ner sizes have less inefﬁ ciency than the ﬁ

Get PriceThe Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger's law. Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize
Get PriceGenerally, 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
Get PriceA "Bond" rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner (one of the four laboratories is known to be investigating replacing the liner with a wave
Get PriceRod 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, from 10 mm - 20 mm down to about 2 mm.
