The study relates to the preparation of metallic and non-metal-lic components of blended materials and industrial wastes, for pyro-metallurgical processes. The design improvement for roll briquetting press was proposed for compaction of granular materials used as raw materials for pyrometallurgical processes. One of the rolls was invited to perform with cells, and the second - with a smooth surface that can dramatically reduce the cost of manufacturing the tool. The authors have implemented physical modeling of the process using the installation of the original design when changing the configuration of the cells in two versions: radial and triangular in shape. Physical modeling has shown that in the proposed scheme of the implementation process it is advisable to use cell of radial profile, which leads to the achievement of large volumetric deformations of compressible material.
