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.Email:[email protected]
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 ...
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.
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
Here is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load.
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).
