Electric oven for roasting vermiculite concentrate

摘要

The invention relates to the field of building materials, namely for production equipment for the production of exfoliated vermiculite. Electric furnace for firing vermiculite concentrate is characterized in that in the space between the heat chamber is arranged a module made of steel sheets with insulating layers, forming a flat slit-like chamber that is connected with the exciter, the conical coil springs mounted in the bottom of the module, and coil springs disposed in the upper part of the module, provided with rollers resting on guides, fixed on side surfaces not electrified baking outside goods giving axes of the rollers facing outwardly in the longitudinal slots of the side surfaces. Technical result: the energy efficiency of the electric furnace for firing vermiculite concentrates. 4 yl.
