Opis:: The paper presents the results of coal milling tests in the aspect of slurry fuel preparation. The tests were carried out with the use of vibrating mill with a working chamber of 47.5 dm³. The influence of milling time, amount and composition of grinding aids on the degree of fineness and particle size distribution have been investigated. It was found that the efficiency of the grinding process (in this type of milling device) depends primarily on the milling time and the share of grinding aids and – to a lesser extent – on their polydispersity. The study allows to conclude that the grinding time, composition and the share of used grinding aids enable to control the final grain size of coal, which has an impact on apparent viscosity of coal water slurry.

Opis:: The article presents the results of studies of torrefied willow (Salix viminalis L.) compaction. Densification tests were performed using a hydraulic press with a maximum pressure of 216 MPa. The effect of basic parameters of the briquetting process (pressure and temperature) on mechanical parameters of manufactured briquettes were determined. On the basis of the research, it was found that the increase in pressure and temperature of the densification process increases the density and strength of pressed briquettes. The positive effect of temperature is particularly noticeable at lower pressing pressures (36 MPa – 72 MPa). In the case of a temperature of 300 C, the increase in a pressure from 144 MPa to 216 MPa resulted in the decrease in the density and strength of the briquette. It was also found that the briquettes manufactured at this temperature are characterized by lower density and strength than the briquettes obtained at a temperature of 200 oC.
