GRINDABILITY TESTS Bond Rod mill work Index • The rod mill work Index is also normally distributed with and average and median of 14.8kWh t • It is common to observe difference between the ball and rod mill caused by variation in ore hardness • The test has been mainly used for the design of rod mill or primary ball mills. http.According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250 circulating load (Bond, 1949, 1952, 1961).
May 26, 2015 Bond Work Index (BWI) Hardgrove Grindability Index (HGI) tests for biomass coal. BWI can predict the potential for mill choking of biomass in a tube and ball mill.Oct 20, 2020 The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. What is Bond ball mill work index Abstract The Bond work index is a measure of ore.
