FIELD: chemistry.
SUBSTANCE: invention relates to production of construction materials, namely to production of cement clinker. Method of obtaining cement clinker includes breaking of raw material components, crushing of hard fuel, homogenising and granulation of mixture of raw material components with hard fuel until cores with 1-5 mm size are formed, loading of obtained pellet charge into sinter pot, further charge igniting by supply of gaseous fuel and its thermal processing at air supply under excessive pressure 45-285 kPa. Specific air consumption ensures burning of hard fuel in charge.
EFFECT: increase of plant productivity, clinker quality, reduction of energy consumption for its production.
