The article discusses the research of peat physical and mechanical treatment which consists in determining technological parameters of peat stock. Size distribution and conditional specific surface area of peat particles are set. The relationship between processing efficiency and the content of peat fractions which size is less than 250 microns is derived. It proves to be linear. Treatment efficiency is found to be estimated by the data of a screen analysis alone and with satisfactory accuracy. Mechanical treatment has an effect on the values of total moisture capacity. The dependence is nonlinear and decreases insignificantly up to the conditional specific surface area of 350 m2/kg due to the partial grinding of fibrous coarse fractions. Mechanical treatment up to the conditional specific surface area of 500 m2/kg results in the sharp decrease of total moisture capacity due to the practically complete destruction of coarse fractions. With that of more than 500 m2/kg the values of total moisture capacity change insignificantly. Multiple peat treatment causes its mechanical consolidation and the reduction of coarse fraction content along with significant increase of fine fraction content.
