Ball Mill An Overview Sciencedirect Topics

ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills is typically vol.-% ore and 25% steel. the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.single stage sag mills are very beneficial in reducing capex for plants with a staged throughput approach. when future tonnage is to be increased, the sag mill can feed downstream ball milling to boost capacity. fuller-traylor sagag mills range in size from through 12. in diameter with powers as high as 28,000 kw.double helical feeders used in closed-circuit with classifiers; spout feeders preferred when using a closed-circuit with classifying cyclones. cyclones are typically installed above the mill and thus the cyclone underflow is fed to the mill by gravity. discharge system. one exit unit; exit about 110 cm lower than the center line of the

Batch Ball Mill For Open Or Closed Circuit Grinding

the batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. the batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.sag mill in closed circuit with two 600 kw pebble crushers sag milling is followed by a ft mw ball mill in closed circuit with a cluster of inch 660 mm cyclones after classification the milling product is thickened and pumped as feed to carboninleach tanks agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. because of the range of mill sizes available, agsag milling can often be accomplished with fewer lines than in a conventional rod millball mill circuit. diagram of types of agsag mills
