Grinding is a random process and is subjected to the laws of probability. Grinding steps: i. Primary (Coarse) grinding (generally a rod mill is used)(Feed size as large as 50 mm, product size as fine as 300 microns)(1000 microns = 1 mm) ii. Secondary (Fine) grinding (generally a ball mill is used)(Feed size as large as 0.5 mm,

QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE …

Abstract: 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, time-
