Silicon powder (99.99 %, particle size 0.05mm) was ball-milled in an attritor ball-mill at 400 rpm for 30 h in hexane. It was found that slurry of ball-milled 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.

Grinding Direction of grinding, especially on nodular iron shafts, is important and should be in the same direction as the bearing will move relative to the shaft. Complete removal of friable or 'white' layer from nitrided journals is essential. This implies fine grinding or honing, approximately 0.025-0.05 mm (0.001-0.002 in) from surface. A11 ...

The grinding balls roll halfway around the bowls and then are thrown across the bowls, impacting on the opposite walls at high speed. Grinding is further intensified by interaction of the balls and sample. Planetary action gives up to 10 g acceleration.
