We perform the energy analysis of an electric furnace with vibrating hearth by using previously developed analytic models of absorption and a new refined model of the assimilation of heat by vermiculite. We deduce a temperature–time equation, the formulas for the productivity of the furnace unit and the specific energy consumption of calcination of the vermiculite. It is shown that the furnaces based on a new concept have specific energy capacities that do not exceed 77.8 mJ/m3, which is more than three times lower than the specific energy capacity of the flame furnaces intended for the purposes of roasting of the vermiculite.
