Purpose. To determine the granulometric composition of technogenic raw materials for agglomeration by the adhesive-chemical method. This approach allows for determining the optimal particle size distribution for obtaining the prepared agglomerated fuel, which has the form of cylindrical rods with a diameter of 30 mm and a length of 50 - 200 mm. Methodology. The granulometric composition of technogenic raw materials was determined using sieve and sedimentation analyses. 38 representative samples of carbon-containing raw materials were subjected to the investigation. Findings. The sieve analysis results of representative samples of coal sludge and culms are presented; their graphical characteristics is given. Sieve analysis of the granulometric composition of samples of carbon-containing raw materials and sedimentation analysis of solid fuel samples with a fraction of fewer than 50 microns is carried out. It has been established that all samples with sizes of more than 5 - 6 mm should be subjected to further grinding. Originality. For the first time, studies and comparative analysis of granulometric compositions of technogenic raw materials have been realized, which allows for a reasonable approach to obtaining composite fuel from carbon-containing wastes by the adhesive-chemical method, using various compositions of components. Practical value. The results can process technogenic raw materials to get agglomerated fuel of specified parameters by the adhesive-chemical method and other processing areas, including using carbon-containing waste from various productions.
