INVESTIGATION OF THE INFLUENCE OF THE SCREEN SYSTEM PARAMETERS OF DRUM WOOD CHIPPERS ON THE FRACTIONAL COMPOSITION OF INDUSTRIALWOOD CHIPS

Abstract

A pattern has been established in the variation of the percentage of substandard fraction of wood chips in the total mass of industrial chips depending on the parameters of the screen system of drum wood chippers. A regression equation was obtained, which can be used to calculate the percentage of substandard fraction, taking into account the number of sections of the stepped screen, the radial distance between the screen and the drum, and the moisture content of the wood. Optimal parameters for the screen system of drum wood chippers have been established.
