Insmart bonds ballmill work index is a measure of the resistance of the material to grinding in a ball mill this index is widely used in the industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill scaleup

The work index calculated from the testing can be used in the design and analysis of ball mill circuits the test requires a minimum of 10kg of sample that has been stagecrushed to 100 passing size of 335 mm any screen size below 600m can be used for the testwork depending on your requirements bond rod mill grindability test

A bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits 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 335 mm as required for the bond ball mill work index test feed

Bond s work index ball mill manufactuering design ball mill wikipedia a ball mill is a type of grinder used to grind blend and sometimes for mixing of materials for use in mineral dressing processes paints pyrotechnics ceramics and selective laser works on the principle of impact and attrition size reduction is done by

Ball mill design requires a bond work index bwi for ball mills at the correct passing size sag mill design requires 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

Bonds approach consists of determining the ore hardness characteristics or work index wi via standardized laboratory testwork the full suite of bond comminution tests provide the ball mill work index bwi the rod mill work index rwi the crusher work index cwi and the abrasion index

The d80 of ore reached to 480 m in all samples to prepare materials for ball mill grinding experiments because d80 of plant ball mill feed in sungun plant was 480 m as a base for this study standard bond grindability tests were initially done and bond work index

For every bond ball mill work index test carried out at jktech a standard report is issued the report details the bond test procedure method and presents the results including f80 p80 grindability and work index further interpretation of the results is available if required frequently asked questions bond ball mill work index

Laboratory ball mill if the mill diameter is greater than 381m the cylindrical feed characteristics the laboratory ball mill was designed for grinding limestone meaning that the work index required for the specific power calculation was assumed to be the work index of limestone which is 116 kwht with a specific gravity of 26 gcm 3

A bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits 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 335 mm as required for the bond ball mill work index test feed
