The article presents the technology and energy-saving equipment for producing a composite binder with a reduction in the energy cost reduction of the process up to 50%, due to the synergistic effect of mechanical activation of the raw material mixture with the replacement of the clinker component with a mineral hydroactive additive. The energy efficiency of the line is achieved by the joint work of the press-roll unit, and the rotor-vortex mill of superfine, which allow the grinding of raw materials to a dispersion with a specific surface area of 4000…4500 cm2/g. The resulting equation for calculating the effort of grinding materials, which is implemented between the conical rollers in the press-roll unit (PRU). It has been established that the power spent on grinding the material and overcoming the friction in the axles of the pivots rolls and proposed the equation for calculating its variable.
