associated loss of throughput and grind are well recognised on lowaspect singlestage SAG mills However it is becoming apparent that a

Jan 01 2016 · Low aspect mills are best suited to lowtomedium competent ores while high aspect mills are more commonly used for competent ores either as singlestage circuits or autogenousball mill twostage circuits The larger diameter and short length provide better impact breakage for the competent ore 93 Operation of AGSAG Mills 931 Feed Size

Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long For this reason rod mills are rarely selected in the present day environment of large AGSAG mills and large ball mills However it is necessary to discuss their operation because a Rod mill product has a similar slope to AGSAG mills

These lowpower high torque auxiliary drives allow you to control mill rotational movement from an inching pace to of up to two revolutions per minute Theyre designed and engineered to help elevate safety prevent load freezing simplify maintenance extend component lifetimes and maximize mill

The SAG Power Index SPI test Starkey Dobby 1996 uses a benchscale SAG mill test to determine the specific energy of an industrial SAG mill The test is operated in closed circuit and the time required to grind the material to a P 80 of 17 mm is used to predict AGSAG

Ball Mill Lubrication Many mines or electric generating stations require raw minerals to be ground and pulverized for final processing This process can be achieved through one of the different types of ball mills used – SAG Mill‚ Ball Mill‚ Rod Mill and Double Ended Ball Mill included

Safe and speedy replacement Thinner mill liners result in a larger volume inside the mill This means you can have a higher charge level Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners making it possible to work with a higher ball charge level without increasing the total weight of the mill
