High energy ball milling process for nanomaterial …
The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling balls in the bowl.

Preparation of copper-graphite composite particles …
The composite graphite amount per 1 g of copper particles increased to 0.46 mg at the milling time 5 min, and subsequently decreased to 0.25 mg at 60 min, indicating the suitable milling-time for the interfacial adhesion. When using only the copper particles, the naturally oxidized layer on the surface decreased with milling.

Ball Mill: Operating principles, components, Uses ...
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
PREPARATION OF COMPOSITES
For the preparation of composites, we selected 118 individual samples from Hole 801C, ~25 samples per 100 m drilled, including 58 samples from cores drilled during Leg 129 (see the "Supplementary Materials" contents list). All samples were characterized and powdered on board; the mixing and homogenization of composite powders will be completed onshore.
