Autogenous and SemiAutogenous Mills ScienceDirect
The designs of autogenous and semiautogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described ABC closed circuit, AutogenousBallMillCrusher Another similar technique is the ABC open circuit where the crusher product feeds the ball mill Autogenous Grinding Semi Autogenous Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 524 meters and length of 884 meters (Morrell, 1996) Autogenous mills range up to 12 meters in diameter The lengthtodiameter ratios in the previous table are for normal applications For primary grinding, the ratio could vary between 1:1and AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill
Semi Autogenous Grinding Mill an overview
An autogenous mill of ID 67 m and an effective grinding length of 21 m was fed with ore of SG 38 to 20% of its volume The mill was operated continuously 24 hours per day at 1200 t per day and 75% of the critical speedThe solids in the mill charge were at 80% solids Estimate:1 The power consumption per tonne per day ballonshell impacts just above the charge toe, owing to the risk of ballonliner damage and excessive metal flow In fixedspeed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angleSemiautogenous grinding (SAG) mill liner design and Ball Mill Application and Design Ball mills are used the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, metal oxides, solar cell and semiconductor materials, nutraceuticals and pharmaceuticals materials down to 1 micron or lessBall Mill Application and Design Paul O Abbe
