FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing molded fuel, which includes coal milling to particle size of less than 2.5 mm, mixing with ground binder, pressing during heating of mixture and pressure of 170-200 MPa, characterized in that bran with particle size less than 1 mm in amount of 4-20 wt.% is used as binding additive, and produced mixture is pressed at temperature of 110-160 °C and pressure from 70-169 MPa to 201-300 MPa.
EFFECT: obtaining molded fuel having high mechanical abrasion and dropping strength.
