In comparison to the second half of the 20-th century, nowadays, the volume of milled peat extraction in Russia is multiply decreased and is about 1,5-2 million tons. Realization of twostage harvesting technology is economically profitable only in case of extraction volume of 50 000 tons per year. Modern scientific researches differentiate peat-extracting companies by extraction capacity between small, middle and large ones. This research presents information on work areas capacity and principles of coupling of technological complexes for milled peat extraction. The work analyzes basic technologies of peat extraction technologies implemented in Russia with explanation of work area classification necessity. There are made and shown the calculations of lower indications of working areas of middle extraction capacities. A flow chart of using of upgraded bunker sweepers is proposed. Implementation of new scheme increases technological coefficients on additional pass on the roll. Modern approaches to graduation production areas in terms of production of milled peat harvesting and given conditional humidities are presented. Criteria to areas of low, medium and large capacities are set. Final (harvesting) humidity and conditional humidity of finished products were set as additional conditions to graduation production areas in terms of production. At the stage of production area designing, the developed method enables to conduct explanation of use of the best options for configuration of process equipment.
