FIELD: chemistry.
SUBSTANCE: method of producing compound fertiliser involves mixing components of the mixture and pelletisation thereof in a granulator while heating. The moment the mixture is fed into the granulator, it is exposed to a jet stream of heat carrier heated to temperature from 110 to 180°C. The moment the mixture is fed, the rotational speed of the granulator is set to 0.167-0.5 rpm. The granulator is inclined at an angle of 2-25° to the horizontal.
EFFECT: production of compound fertiliser with given grain-size and chemical composition.
