[email protected]Cleaning and Storing ofBall Mill Chargeafter theBond Work Index Procedureis done: Add about 500 g of silica sand into themillcontaining theball charge. Seal themill. Rotate for 20 revolutions to clean. Empty themill chargeand sand into theballtry once grinding is complete. Clean out themillusing a brush. Put the lid on themill.
DetailsBall mill designrequires aBond work index, 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 ).
DetailsBond Ball Mill Work Inde Clinker MillingEquipment :bond ball mill work inde clinker- A class of machinery and equipment that can be used to meet the production requirements of coarse grinding, fine grinding and super fine grinding in the field of industrial grinding. The finished product can be controlled freely from 0 to 3000 mesh.
DetailsTheBond Ball Mill Work Index(BBWi) test is carried out in a standardisedball millwith a pre-defined media and ore charge. TheWork Indexcalculated from the testing can be used in the design and analysis ofball mill circuitsThe test requires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of <3.35 mm.
DetailsTheRod Mill Work Index(RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereasBall Mill Work Index(BWI) is used for the range from 2.1 mm down to 100 µm. Adjustment of grinding parameters: The operation display permits convenient selection and storage of parameters such as rotation counter, rotation speed, grinding time, start and stop. Product …
DetailsTheBondmethod of grindability was applied toclinkerand trass and to their mixtures. Kinetic experiments also were carried out in theBond ball millwith each component and the mixtures to obtain a better understanding of the interactions taking place in mixture grinding.
DetailsThe Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial...
DetailsInsmartBond’sBall-Mill Work Indexis a measure of the resistance of the material to grinding in aball mill. ThisIndexis widely used in the industry for comparing the resistance of different materials toball milling, for estimating the energy required for grinding and forball millscale-up.
DetailsABond Ball Mill Work Indexmay 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 Mill Work Indextest feed.

The test determines theBondRodMill Work Indexwhich is used withBond’s Third Theory of Comminution to calculate net power requirements when sizingball mills*. Various correction factors may have to be applied.
DetailsSep 08, 2013· The difference between the EnergyIndexand theBond Work Indexis that theBond indexis intended for use with actualmillswhereas the EnergyIndexis directly obtained from the results of laboratorymills. However, the EnergyIndexis directly related to theBond Work Indexby the formula;-Work Index= C * EnergyIndex(where C is a constant ...

DetailsDetermining theBond work indexis a standardized method for characterizing the comminution performance of mineral samples. CEMTEC uses this method for designing rod andball mills. The comminution performance is, just like the desired comminution step and the production capacity, crucial for determining the requiredmillsize.
DetailsJul 31, 2014· The following modifiedBondequation was proposed for crushing (Magdalinovic, 1990): Wc = cP A Wi ( cP 10 - cF 10 ) (8) where: Wc - is energy consumed forclinkercrushing (kWh/t), Wi - isBond ball mill work index(kWh/t), Pc -is sieve size passing 80% of theclinkerafter crushing (µm), Fc - is sieve size passing 80% of theclinkerbefore ...
DetailsTheBond ball mill work indexof each sample was measured using the standard equipment and procedure (Bergstrom, 1985) using a constant closing sieve of 300 μm. In all tests, material passing the closing sieve was removed from the feed, in an attempt to limit the influence of variations in feed size distribution in the test.
