Get Price2016-6-6 Traditionally, many engineers approached SAG circuit design as a division of the total power between the SAG circuit and ball-mill circuit, often at an arbitrary power split. If done without due consideration to ore characteristics, benchmarks against comparable operating circuits, and other aspects of detailed design (including steady-state tests, simulation, and experience), an arbitrary power split between circuits

Get Price2014-10-1 Single stage mills can be run without a variable speed drive however optimal performance is rarely achieved.If the mill is not installed with a variable speed drive or a pebble crushing circuit, options for controlling the mill arelimited. The parameters remaining to control the mill are feed manipulation (changing the feed rate or altering feederratios to adjust the ratio of rock to fines), milling density and the target mill load level. These variables are often notenough to optimise mill performance. A variable speed drive allows the mill speed to be increased, increasing coarserock breakage if the mill is load restricted and over grinding. Slowing the mill
