Analysis of disintegration efficiency in soft rocks with plastic properties in design of compound assembly for such rock processing

Immense attention is given to stimulation of rock processing efficiency in the world. However, there are yet no unified procedures for the evaluation of disintegration efficiency in materials with different properties. This study analyzes current techniques in determination of rock fracture parameters and puts forward a new approach to investigation of grinding processes in soft rocks with plastic properties. The theoretic framework of rock fracture as well as the standard methods of grinding and classification of different materials are reviewed. It is justified that it is necessary to create a new type equipment for integrated processing of weak materials with soft properties. Such equipment makes it possible to perform simultaneously grinding and classification of soft rock particles within a single cycle, without interim storage and transportation of middlings. Conceptual design of a compound assembly–a disintegratorclassifier–is developed, its operating principle is described, and engineering analysis of the most significant parameters of processing soft rocks with plastic properties is partially discussed. The results of the efficiency enhancement in processing of soft rocks with plastic properties using the disintegrator–classifier are presented.
