Рroduction of light fillers on the basis of technogenic raw materials

Abstract

In Ukraine, along with the growing demand for tonnage production of light fillers, the need for raw materials is growing, considering that most of the range of light fillers is made from natural raw materials. Thus, a promising direction of utilization of TPP slags and coal concentrate obtained by enrichment of primary coal sludge is there involvement to the production process after preliminary drying. Drying of the thermal power plant slag and the coal concentrate, which are hydraulic mixtures, by the filtration method will reduce energy consumption due to the displacement and removal of significant amount of moisture by the moving thermal agent due to the pressure drop. The results of studies of the thermal agent velocity effect on the drying process duration of TPP slag and coal concentrate, as well as the obtained values of heat transfer coefficients at different velocities of the thermal agent for TPP slag α = 40 ÷ 112 and coal concentrate α = 92,5 ÷ 294 will allow to calculate energy consumption and scientifically substantiate the optimal technological parameters for intensification of the drying process of the charge components for porous fillers production.
