We have noticed that this ends up at about 10 MN/mm for large drives
Oct 12, 2017·SAG millmake use of steel balls included with some large and hard rocks for grinding. Thesemillsutilize the balls in making the large fragments of materials broken into pieces. Theballcharge of aSAG millis about 9% to 20%.This process takes place inside the large rotating drum ofSAG millwhich is filled with balls partially
Ball Mill Design. A survey of Australian processing plants revealed a maximumball milldiameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenousmillsrange up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and
Jan 01, 2016· Based on these test results, a 6.7mdiameter × 2.1mlengthSAG milland a 3.3m× 6.1m ball millwere installed for commercial operation in closed circuit with a hydrocyclone. TheSAG millhad a 6–8%ballcharge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1
Themillproduct can either be finished size ready for processing, or an intermediate size ready for final grinding in a rodmill,ball millor pebblemill. AG/SAG millscan accomplish the same size reduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of aball mill

Although thefoundationof the test was based on his practical engineering experience, it was in collaboration with Dawson Metallurgical Laboratories and Outotec that the SAGDesign test was developed. The test consists of a robust laboratorySAGtest followed by a BondBall MillWork Index test onSAGground ore (referred to as S d-BWI)
The basic parameters used inball mill design (powercalculations), rodmillor any tumblingmillsizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desiredmilltonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit …

Our MH SeriesSAG,ball, and rodmillshave a standardizeddesignthat still allows for some customization, ensuring a flexible and easily deployable solution. The range of configurable options include such elements as: Optional split shells to accommodate transport regulations and installation limitations; Bearing brand option
