The test simulates a closed grinding circuit in a standard ball or rod mill. At CEMTEC, these tests are conducted with batch mill quotELLAquot. After determining the Bond work index, the specific comminution capacity is calculated using the formula listed at the bottom of the page, factoring in various correction factors obtained from experience.
test types is possible using a series of empirical relationships between those tests conducted at similar size classes. The commonly used grindability tests included in the database are the Bond work indices for ball milling, rod milling and crushing the drop weight test results A, b, A215b, DWi, Mia, Mic, Mih and

Standard Bond Ball Mill Grindability Test Methodprocedure. here is the old allischalmers bond work index grindability test procedure. the standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. it is screen analyzed and packed by shaking in a 1000cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at ...
Rod Mill Design Calculations . When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.
Bond Ball Mill Grindability Test. BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test The feed sample is stage crushed to 189quot 12 5mm and the test is run under a circulating load The test can also be closed with various sieve sizes but for AGSAG mill analyses the standard 14 mesh 1 18mm sieve is typically used.
