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.

The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a twoinputtwooutput model was applied to describe the system, in which some key indicators of the process were ignored. To this end, a three ...

Ballmilling is a convenient, mechanical, operation used widely for the comminution of minerals, and for the preparation of colloidal dispersions. Patents were taken out in this country for the use of the ballmill, as early as 1S63 by R. Brooman. The early mills were used mainly for the grinding of metalliferous ores and ceramic materials.
