HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom highpressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power ...
Silicon powder ( %, particle size ) was ballmilled in an attritor ballmill at 400 rpm for 30 h in hexane. It was found that slurry of ballmilled silicon in hexane was produced as a result of the milling. This slurry was sprayed into a silica tube at high temperature (800±1100℃) under an argon atmosphere.
