Semiautogenous grinding (SAG) mill liner design and development
Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two With this high aspect ratio, SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in) in diameter These2019年9月1日· It has been reported that the design of end liners affects both the grinding efficiency and the rate of metal wear in Aerofall SAG mills (Coles and Chong, 1983) These observations suggested a detailed understanding of the behavior of the charge motion in the original system as a prerequisite to arrive at an optimal liner designOn dry SAG mills end liners: Physical modeling, DEMbased
What’s the Difference Between Ball Mill, Rod Mill and SAG Mill?
2020年3月20日· Ball mill： Ball mills are the most widely used one Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low91 In a SAG mill the dimensions of the mill were 975 m × 35 m and the specific gravities of the mineral and that of the balls charged were 41 and 79 respectively The mill was rotated at 75% of its critical speed when 8 % of the mill volume was charged with grinding balls Estimate: 1 The mill power drawn, 2Semi Autogenous Grinding Mill an overview ScienceDirect
