Abstract: The article considers industrial technology and energy-saving equipment for cement and composite binder production with a reduction in energy intensity of the process up to 50% due to the synergetic effect during mechanic activation of the raw mix with the replacement of part of the clinker component with the mineral hydro-active additive. The technological process is based on the sequential introduction of components in dispersed phases into the feed mixture in the grinding path and at the stage of product separation with certain dispersed characteristics. The increase in the energy efficiency of the line is achieved by the joint operation of the press roller aggregate, which is the development of BSTU named after V.G. Shoukhov, and rotor-vortex mills of a very fine grinding of a new design. The experienced design of the aggregate with the device for deagglomeration of the pressed tape allows combining the processes of grinding and disaggregation of the pressed material, thereby reducing the operating costs and increasing the efficiency of using the grinding unit. Comparative tests of cement samples obtained in energy-saving aggregates (PRA + RVM) are given which allowed establishing that their beam strength for compression and bending is higher by 15-20% than the traditional method obtained in a ball mill. An analytical expression is also given that allows one to determine the power consumed for the deagglomeration of crushed and pressed material between the main rolls, taking into account the geometric dimensions of the rolls and the physico-mechanical characteristics of the material
