In this research, the influence of pressing dynamics on the strength of coal briquettes was studied. Strength intervals were studied with the various ranges of pressing screw's compressive force. During the experiments, the following parameters were selected as variable factors: 5%, 7%, and 10% aqueous solutions of paraffin waste; 10%, 15%, and 20% aqueous solutions of alcohol stillage; the amount of prepared binder solution — 10%, 11%, and 12%; nozzle diameters — 20, 25, and 30 mm; compressive forces of the pressing screw — 1.8, 2.4, and 3 kN; and the working chamber diameter — 120 mm.The results of the study showed that when the nozzle diameter was Dmun = 25 mm, the exponential curves on the graphs indicated that the briquettes prepared with a 15% solution of alcohol stillage and a 15% solution of paraffin waste in water met the required quality standards.
