摘要：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.
