The work index covering grinding in tumbling mills of coarse sizes is labelled M. ia. The work index covering grinding of fine particles is labelled M. ib (Morrell, 2008). M. ia. values are provided as a standard output from a SMC Test ® (Morrell, 2004. a) whilst M. ib. values can be determined using the data generated by a conventional Bond

Get PriceCrushing Work Index. The kilowatt-hours per tone (kWh/t) will work out your work index. The number of kittowatts consumed in a hour divided by the tonnes of rock gives you your work index. Remember, the higher the Work Index the more work required to crush the rock. This will impact the equipment chosen for your project.

Get PriceThe Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and

Get Price1.12.2007· The Bond crushing work index is a measure of material strength and is determined using a simple twin pendulum apparatus and a standard procedure. The Bond impact test attempts to emulate the crushing action that occurs inside the chamber of jaw, cone and gyratory crushers, where particles may not be broken in the first nipping cycle, but only after repeated compression.
Get PriceBond Work Index Tests. Grinding Solutions offers a range of Bond Work Index Testing from crushability and abrasion to ball and rod mills. For more information on the tests please see below: Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index.
Get PriceThe Bond low energy impact (crushing) work index test is specified to be performed on rock specimens between 50 mm and 75 mm in effective diameter. NQ-diameter drill core, frequently used in mineral exploration programs does not meet that specification, it being 45 mm diameter or less.
Get PriceThe Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.
Get PriceAbstract: The 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 comminution plants designing. Determining the Bond work index
