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 Price
Ball mill bondworkindexfor limestone. ABond 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 ...
The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed tominus 3 35mmand size a representative sample The test then involves a series of batch grinds in a standard Bond mill A Bond mill is0 305mby0 305mwith rounded corners a smooth lining and runs at 70rpm The charge consists of 285 balls weighing a
Bond/Rowland Single StageBall MillModel. This is a multi-stage crushing plant feeding aball millmodel that estimates the specific energy consumption (E BM) using the Rowland interpretation of the classicalBondworkindexequation including Rowland efficiency factors.. Testwork Required

XMGQΦ305 Grinding WorkIndex Ball(Rod)Mill. Description; XMGQΦ305 GrindingBond Ball(Rod)Millis mainly applied for testing the grinding workindexof the material of every kinds of ores, slag, etc. Under the specific rotation speed for dry grinding, then screening the products, weighing, repeat operation several times, getting the ...
Oct 03, 2012 TheBond Ball MillWorkIndexon SAG ground ore is 10.55 kilowatt hours per tonne of material, a relatively low amount of energy required to grind the material in aball millRead More TheBond ball millgrindability test measures hardness as anindex, regardless of the feed size, so it does not give credit for the additional fines.
BondWorkIndexProcedure and Method. 2020-05-18· Cleaning and Storing ofBall MillCharge after theBondWorkIndexProcedure is done: Add about 500 g of silica sand into themillcontaining theballcharge. Seal themill. Rotate for 20 revolutions to clean. Empty themillcharge and sand into theballtry once grinding is complete.
TheBond 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.
The 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).
ABond 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.
BondRodMillGrindability 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
