Rubric:  System analysis and processing of knowledge

Annotation:  The article describes the methodology for selecting the design of the intra-mill device of a ball mill. The analysis of the blade energy-exchanging devices was carried out and the characteristics that reduce the number of mills were highlighted. On the first stage of the method, the obviously unsuitable variants of intra-mill devices are removed according to specified criteria; on the second stage the final selection of mills according to technical and economic indicators with the use of the analytical hierarchical procedure was made. A classification of intra-mill bladed energy-exchanging devices is represented; a summary table of the primary data of the characteristics of VED is compiled. A description of the subject area is presented, criteria are highlighted and relationships between them are determined, multi-criteria evaluation of the designs of vane ellipse energy-exchange devices was carried out. As a result, recommendations on the choice of the optimal intra-mill device during designing the construction of a ball mill were formulated

Keywords:  ball mill, vane energy-exchange device, multicriteria approach, decision making, hierarchy analysis method, vane energy exchanger
