The Bond Index conforming rod charge consists of: 6 rods of 1.25“ diameter and 21“ length. 2 rods of 1.75“ diameter and 21“ length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Jul 15, 2013 Jul 15, 2013 In the standard A-C closed circuit ball mill grindability test the work index is found from. where Pi is the opening in microns of the sieve mesh tested, and Gbp is the net grams of mesh undersize produced per revolution of the 12″ x 12″ test ball mill. The closed circuit 80% passing size P averages P1/log 20 for all sizes larger than 150 mesh.

Oct 15, 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. ? HGI is a poor method of predicting grindability of biomass in vertical spindle mills. ? Pellets should be composed of pre-densified particles close to the target size. ?
