bond ball mill work

Ball mill designrequires aBond workindex, BWi, forball millsat the correct passing size;SAG mill designrequires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).

You can find the SG of each mineral samples on the other table. Source 1: Table of materials reported by FredBond. Source 2: Outokumpu, The science of comminution. Source 3: Equipment and pipelines.

TheBond Ball Mill WorkIndex is 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 mill grindingconditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

The ability to simulate theBond work index testalso allows examination oftruncated ball mill feedsize distributions on theworkindex For grinding circuits where the feed to aball millis sent directly to the classifier and the cyclone underflow feeds theball millsee Figure 3 10 a question arises as to whether this practice will alter theball mill workindex BW i of the material

TheBond Ball Mill WorkIndex (BBWi)testis carried out in a standardisedball millwith a pre-defined media and ore charge. The test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of <3.35 mm.

Where W = Net power consumption inkWh/t Wi= Bond work index (either Imperial or Metric units) P = The 80% passing size of the ground product in µm F = The 80% passing size of the feed in µm The test is a closed circuit dry grindability test performed in a standard ball mill.

A typical type offine grinderis theball mill.A slightly inclined or horizontal rotating cylinder is partially filled withballs, usually stone or metal, which grind material to the necessary fineness by friction and impact with thetumbling balls. Endmill- Wikipedia

TheBond ball millgrindability test is run in a laboratory until a circulating load of 250% is developed. It provides theBond Ball Mill WorkIndex which expresses the resistance of material toballmilling. This happens after 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to ...
