Modeling of the process of mechanical dehydration of raw peat materials in the working tools of mining machines

Abstract

Abstract The results of physical modeling of primary dehydration of raw peat materials of the disturbed structure in a thin layer and at excavator bucket digging directly from the watered deposit at peat quarry development are presented. The areas of rational application of mechanical moisture dehydration of raw peat materials are shown, which allow assessing the quality of extracted raw peat materials and products of its processing. By results of the carried out modeling of process of moisture reduction concrete recommendations on size of the basic parameters of working bodies of mining machines are given. In particular, the sizes of press pallets for a gravitational press of primary peat pulp dehydration are selected, the rational size of a column of pallets providing the set parameters of quality of a product of processing directly on board of quarry is revealed. Modeling was carried out and on its basis recommendations on selection of parameters and design of excavator bucket, for mining and primary dehydration of excavated raw peat materials of different compaction degree were given. The presented approximated curves of the dehydration process in the bucket allowed to clarify the parameters of the mining excavator bucket ensuring the specified quality of raw peat materials at the first stage of its extraction and processing.
