This Grindability Test orBond Ball MillWorkIndex Procedureis used to determine theBondWorkIndexof minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in aBall Millusing a standardballcharge. Below describes in general terms theBondWorkIndex Procedureused by a Professional Metallurgical Testing Laboratory.

Get PriceABond Ball MillWorkIndextest is a standard test for determining theball millworkindexof a sample of ore It was developed by FredBondin 1952 and modified in 1961 (JKMRC CO, 2006) Thisindexis widely used in the mineral industry for comparing the resistance of different materials toball milling, for estimating the energy required.
Get PriceTheBond Ball MillWorkIndexis 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 millgrinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
Get PriceThe standardBond Ball MillWorkIndextest procedure is firstly to stage crush the feed to minus 3 35mm and size a representative sample The test then involves a series of batch grinds in a standardBond millABond millis 0 305m by 0 305m with rounded corners a smooth lining and runs at 70rpm The charge consists of 285 balls weighing a ...
Get PriceABond Ball MillWorkIndexmay also be used in the simulation and optimisation of existingmill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for theBond Ball MillWorkIndextest feed.

Get PriceThe ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of45-150 µm(325-100mesh), thus determining the ball mill work index (WiB or BWi).
Get PriceBondRodMillGrindability Test. The test determines theBondRodMillWorkIndexwhich is used withBond’s Third Theory of Comminution to calculate net power requirements when sizingball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rodmill. Contact Us
