Sag Mill Testing Test Procedures To Characterize Ore :

design a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill will operate over a coarser size reduction range as measured in the rod mill test, which may exhibit different grindability characteristics than would be observed at the ball mill index range. table compares the typical range ofseveral grindability tests were developed over the years to design grinding circuits or optimize existing operations. each test has its own strengths and weaknesses and it is imperative to select the proper test procedure to meet project deliverables and minimize the risk of a project. pilot plant testing of large bulk samples historically constituted the traditional approach for AG or sag jan 01, 2012 the bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. however, the mass of ore required to conduct the test, which can typically vary from about to as much as kg, may represent a challenge when sample availability is critical.the present work proposes an alternative procedure, which is based on the size-mass balance model with a
