Abstract: A raw mixture for the production of a cement clinker which consists of lime, argillaceous and ferrous components and a mixture of chlorides of calcium, potassium and sodium, the components being contained in the following proportions, percent by mass:lime component --55 to 63argillaceous component --23 to 17ferrous component --4 to 1calcium chloirde --17.8 to 4potassium chloride --0.1 to 7.5sodium chloride --0.1 to 7.5.The raw mixture is useful in the low-temperature processes for production of cement. The use of the raw mixture according to the present invention makes it possible to utilize alkali-containing raw materials (soda production wastes, cement dust recycle).

Abstract: A device for recovery of chlorine-containing compounds from waste gases having a chamber for passage of waste gases, including an inlet and outlet pipes and fans arranged in pairs inside the chamber along the gas flow, one opposite another, their blades being arranged parallel to the flow of waste gases through the chamber.
