Bond 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 LowEnergy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index.
As the HGI ball mill works on the same principle as pulverizing mills, the index obtained from this could give a fair assessment of the grinding capability of torrefied biomass. For biomass, one should use ( Agus and Waters, 1971; Joshi, 1979 Agus and Waters, 1971 Joshi, 1979 ) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied biomass.
ball mill for measuring grinding work [randpic] Ball Mill an overview ScienceDirect Topics The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ). The feed can be
Key properties of grinding media are size, density, hardness, and composition. Ball Mill Grindability Test is carried out to determine the work index. Work Index is calculated in order to get the power required to reduce a material with a given 80% passing size to a specific product with 80% passing size.
