The purpose of this paper is to present the methodology of experimental testing of the friction coefficient between compressed sawdust and steel at increased temperature. The subject has been inspired by practical engineering experience in the design of machines for compression of natural materials classified as biomass, such as sawdust. Sawdust is a structurally complex material and investigation of its interaction with components of agglomerating machines is a prerequisite for determining the optimum parameters of the compression process. The paper presents a special test facility developed by the authors for experimental testing of the friction coefficient in loose materials subjected to the effect of heat. Moreover, it presents the experimentally determined values of the friction coefficients for various sawdust types as a function of temperature. The output of the research relates to the processes involved in compression of natural waste materials to obtain renewable sources of energy - environment-friendly fuels.
