Choosing a SAG Mill to Achieve Design Choosing a SAG Mill To Achieve Design Performance John Starkey1 Principal Consulting Engineer Sami Hindstrom2 Manager Grinding Travis Orser2 Project Manager GrindingToday we will learn about difference between sag mill vs ball mill A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding crushing or cutting

Get PriceFrom the literature it is apparent that in circuit design some approaches to the sizing of AG/SAG mills as well as the ball mills that they feed use this parameter This paper reviews whether the SAG Mill Grinding Circuit Design AG and SAG mills are now the primary unit operation for the majority of large grinding circuits and form the basis for a variety of circuit configurations

Get PriceWhile AG mills operate without a ball charge SAG mills use a grinding media charge of normally 3 12 for comminuting the feed material The maximum feed size is between 200 mm and 500 mm The maximum feed size is between 200 mm and 500 mmPage ii filling in the mill and not related to total mill filling Discharge through an individual opening on the grate is driven by the factors of ore filling radial position and the size of the

Get PriceHowever in sag mills and in partcular ag mills the grinding media derive from the feed ore The feed ore hardness and size distribution therefore dictate the number and size distribution of the grinding media which will vary greatly from mill to mill and ore type to ore type It is this factor which has remained central to the problems facing modellers of ag and sag mills To some extent this I 203 INFLUENCE OF FEED SIZE ON AG/SAG MILL PERFORMANCE SMorrell1 WValery 1 1JKMRC Isles Road Indooroopilly Qld Australia e mail smorrell mailboxuqeduau
