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 PriceTheBond Indexconformingball chargeconsists of: 43 x 1.45”balls; 67 x 1.17”balls; 10 x 1”balls; 71 x 0.75”balls; 94 x 0.61”balls; The optimum number of grindingballsis 285. However, theballdiameters vary due to wear. Therefore, the totalball numbershould be adjusted from time to time to ensure a total mass of 20.125 grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well …

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.
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
First, a JarMillgrindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, aBondWorkIndexdetermination, results in a specific energy value (net Hp-hr/t) from an empirical formula.
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.
