Raw Material Drying-Grinding - Cement Plant Optimization

To measure grindability, Bond developed 'Bond's Work Index' (BWI), a 'test mill' and a testing procedure for WI. With the help of this we can work out power required to grind a material from a given feed size to a product of given fineness. Other index known as 'Hardgrove Index" is also used to scale grindability of materials, particularly coal.

[PDF] A quick method for Bond work index approximate value ...

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 value is quite complicated, timeconsuming and requires trained operating personnel and therefore is subjected to errors.
