Study of the process of processing felling residues in the conditions of logging operations

Abstract

Until recently, only the trunk was recognized as valuable in the forestry industry, and everything else, including the crown, was considered waste that cluttered the areas of cutting areas, and was also considered a dangerous raw material in the event of possible fires. Currently, only about 700 thousand tons of wood waste is used, which is no more than 4% of the resulting amount of potential raw materials that could be used at wood processing enterprises. Analysis of the processes of formation and use of felling waste showed that today coniferous greenery has found its application as a raw material for the production of coniferous flour, which is produced directly at the cutting area. After the needles are separated, branches remain in the cutting area that have not found further use. One of the promising areas for the use of logging waste after the separation of needles is the production of wood flour, which has found its wide application in many industries. In the course of research, a design of a mobile device for processing felling residues in a felling area into wood floor was proposed and a laboratory prototype was made. In the course of the analysis of the results of experimental studies, the influence of the design and technological parameters of the device for obtaining wood flour from felling residues on the quality indicators of the finished marketable product was revealed. Statistical and mathematical equations and graphical dependencies have been obtained, which make it possible to predict the qualitative characteristics of wood floor for given design and technological parameters.
