Live ChatCOPPER MOUNTAIN OVERVIEW ON THE GRINDING MILLS AND THEIR DUAL PINION MILL DRIVES Without the speed flexibility on the ball mills, the operator would somehow have to live with the available options and can only just either add balls (but not take them out easily) or switch on / switch off the ball mills and therefore most likely will end up sometimes with either re circulating loads or

Live ChatThe rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh

Live ChatMetallurgical ContentOptimize Ball Mill Liner ReplacementLorain Shell LinersMill HEAD LINERSMill LINER BOLTSEffect of Liner Design on Mill Performance There are many different designs and styles of ball mill liners. As with grinding balls local economics and ultimately operating costs determine the best design and material to use. The initial set of liners is rarely the final design selected.

Live ChatIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Live ChatGravity induced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a media slurry mixture, resulting in size reduction.

Live ChatAll Grinding Mill amp; Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

Live ChatWorking Principle amp; Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x 5 where the
