Abstract

Currently, materials made of wood-fiber semi-finished products are widely used in house building as structural, finishing and insulating materials. According to the results analysis of numerous studies, the raw material for their production is technological chips of woodworking waste. While production, the chips are subjected to hydrothermal treatment and further grinding in disk knife grinding machines in two stages. Significant energy consumption of the wood fiber production process is driven not only by grinding wood chips in stages, but also by overcoming the hydrodynamic resistance of the aqueous environment, where grinding is carried out. The process of grinding wood chips, made of from chopping residues, in an aerodynamic medium on an upgraded cross-bar mill was studied in order to solve the problem of expanding the raw material base for the production of a wood fiber semifinished product and reducing the energy intensity of the grinding process. The features of this process were analyzed and its effectiveness was assessed. The influence of the exposure time of wood chips of chopping residues in an acetic acid solution, the size of the working gap and the angle of inclination of the front edge of the knife on the grinding degree and fractional quality of wood pulp grinding was determined. Statistical and mathematical equations, that describe the studied process, were obtained, and the graphical dependencies are constructed. The following basic requirement is fulfilled for the dependencies: the experimental points for a total should lie quite close to the curve. These equations allow predicting the quality of wood pulp depending on the set modes of the grinding process; as well as determining the quality indicators of wood pulp with known values of the technological and structural parameters of the grinding machine. The efficiency of the process of obtaining the wood-fiber semi-finished product in an aerodynamic environment from wood chips produced as a result of chopping residues (branches, twigs, etc.) processing in a mobile wood chipper, is proven.
