Centrifugal casting consists of a number of processes in which the centrifugal force set up by the rotation of a part of the casting is utilized to shape the casting, fill the mould and help solidify and strengthen the metal [Pavlovic, et al (2009)]. There is a difference between vertical centrifugal casting and horizontal centrifugal casting.

1. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1].During operation, the grinding balls execute motion paths that result in frictional and impact effects.

Centrifugal Casting Controls Impurities. Unique to the centrifugal process is the high force that effectively isolates less dense substances in the casting's bore area. These impurities are later machined away, leaving a defect free part. Molten metal is fed into a rotating mold where a centrifugal force of up to 100Gs is applied to the metal.
