| Popis: | We perform the analysis of the available empirical compaction equations for fine-fraction materials. By modeling separate stages of the process of compaction for selected groups of materials, we reveal the advantages and drawbacks restricting the fields of their possible applications. It is shown that the compaction equation proposed at the Z. Nekrasov Institute of Ferrous Metallurgy of the NAS of Ukraine (IFM) is the only dependence that can be successfully applied to fine-fraction materials of the mining and metallurgical complex (MMC). The necessity of subsequent improvement of the indicated equation is substantiated.We propose two compaction equations whose joint application enables one to predict the relationship between the pressure and the degree of compaction in the process of briquetting within the technological range of pressures. These equations allow one to identify the stages of pressing and study the factors affecting the process. They can be also used to optimize the technological conditions of briquetting of materials of the MMC and to increase the reliability of determination of the power-and-force parameters of the process of pressing. |
