General Remarks of Comminution and Separation Technology

Abstract

This paper describes the outline of comminution and separation technology for creating the “Sound Material Circulation Society”. In especial, the importance of such technology was emphasized by introducing the “3R” concept. Improving mechanism of the liberation of compositional materials in comminution process, properties of two kinds of separation technologies, soft and hard separations, applicable size range for soft separation, adequate combination flow of separation technologies, and evaluation method of separation results were introduced.
