The actual methods of perlite drying are established. The radiation method of perlite drying is offered. A description of an experimental installation for drying perlite by the radiation method is given. The kinetic regularities of this method are established. Graphical dependences of moisture content on drying time, perlite surface temperature on drying time, and drying speed of perlite on drying time are described. The influence of the initial moisture content of perlite, the value of the heat flux density from the infrared emitter, the thickness of the perlite layer, and the value of the perlite fraction were determined. The analysis on the resulted graphic dependences is made. A drying installation with a combined drying method is proposed. The general conclusions concerning the expediency of a radiation method of drying perlite are made.

Thermal resistance can be increased by using proper heat insulation materials. Traditional heat insulation materials do not stand all desired properties. Thus, developing new heat insulation materials is very important. In this study, expanded perlite based heat insulation material was developed as an alternative to the traditional insulation materials. The composition of the developed material was designed and prepared using the theoretical thermal conductivity prediction models. The prepared material was molded in a rectangular shape panel. Thermal conductivities of panels were measured experimentally and the results were compared with the calculated results. Also, the results showed that the developed panels can be used for heat insulation applications. On the other hand, the closest model to the experimental results is the parallel model whose average deviation is 4.22% while the farthest model is the Cheng and Vachon model whose average deviation is 12.43%. It is obtained that parallel and series models are generally in good agreement with the experimental results. Nevertheless, it is seen some deviations between experimental and theoretical calculation results. The theoretical prediction models do not include any processing conditions such as molding and curing. It is thought that these deviations have originated because of the missing processing parameters in theoretical prediction models. As a result of experimental studies, the lowest thermal conductivity value of expanded perlite based panels was obtained 43.5 mW/m.K. Consequently, the heat transfer coefficient of the panels containing expanded perlite can be calculated nearly by the parallel method.
