摘要：Here is offered a method of production of unburnt synthanite from natural minerals using apparatus with vortex layer of ferromagnetic particles. There was fulfilled comparative quality analyses of anhydrite binding substances, produced by anhydrite rock milling together with complex solidifying activator in traditional ball mills, and substances produced by our method. It was stated that achieved rising of the hydration activity of synthanite by collective milling of the raw material components was a result of ferromagnetic particles hindered impact under magnetic field influence. The reason for such activity is not only increase in specific surface area of the milling material, but changes in anhydrite structure at the crystalline grid level, preserving a lot of defects on the separate particle surface.
