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

High Energy Ball Mill High-energy ball milling is an already established technology, however, it has been considered dirty because of contamination problems with iron. However, the use of tungsten carbide component and inert atmosphere and /or high vacuum processes has reduced impurity levels to within acceptable limits.

Ball mill is easy to operate and process in a mild condition, and can decrease the size of inorganic or metal particles for uniform dispersion in the matrix. This advantage is conducive for the preparation of composites at low temperature, and beneficial for further heat press molding to generate coordination reaction.

Preparation of wood flour. Ball-milling was performed using a planetary ball mill (Pulverisette 6; Fritsch Japan Co., Ltd., Japan). For each load, WF (13.5 g) and distilled water (200 mL) were milled with 25 balls (diameter: 20 mm) in a cycle consisting of 10 min of milling, followed by a 10 min pause, for the prescribed time.
