Ball Mill Design/Power Calculation

Jun 19, 2015· If this is not available, standard grindability tests can be run to provide approximate values. Rod and ball mill grindability test results should only be applied to their respective methods of grinding. If P is less than 80% passing 70 microns, power consumption will be; Ball Mill Power Calculation Example #1Bond Work Index Formula-Equation,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.Bond Work Index - an overview | ScienceDirect Topics,where P 1 is the sieve opening in microns for the grindability test, G b.p. (g/rev) is the ball mill grindability, d p is the product particle size in microns (80% of product finer than size P 1 passes) and d f is the initial feed size in microns (80% of feed passes).Mineral Processing - SlideShare,May 15, 2014· A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant . It is determined by Bond Ball Mill Grindability test in a lab using a Bond Mill. Grindability is the number of net grams of ( screen ) undersized product per revolution of the mill .Hard Rock Lithium Processing - SGS,SGS performs the following grindability tests: • SPI test • SMC test • Bond Ball Mill Grindability Test • Bond Impact Test • Abrasion Test • JK Drop-Weight Test • MacPherson Autogenous Grindability Test • MacPherson 18” Mill Test.
