With the advent of a new electric kiln with movable hearth it is possible to determine experimentally the dependence of the density of expanded vermiculite on its temperature. New experimental data have shown that the previous model of heat absorption gave an overestimated result by value needed for full swelling of energy. The experimental results and calculations are presented to demonstrate clearly the new specified and basic indices of model of vermiculite heat absorption. Experimental determination of the temperature of vermiculite found that swelling it effectively requires up to twenty per cent less energy than previously thought according to the first model of heat absorption. And higher efficiency of structurization process indicates several large energy efficiency electric ovens for roasting vermiculite
