FIELD: cement industry. SUBSTANCE: method for cement production includes two-stage processing of cement clinker with its grinding at the second stage in mill, intermediate and final classification. Clinker at the first stage is crushed by inertial gyratory crusher by maintaining material level at the inlet of crushing chamber within 0.3-1.0 of its height, separating particles o cement size from crushing products and returning fraction of -6,0+3.0 mm to crusher for final crushing. During the second stage, fraction of -3.0 mm is crushed. EFFECT: higher efficiency.
