SUBSTANCE: method involves sorting of balances with the selection of defective ones, separation from them those parts of the stem with length of 0.5-0.8 m, which are visually identified as contaminated by rot. These parts are subjected to peeling and chopping at the wood chips in a separate stream. Chips are cut and sorted on the program in accordance with a given size of chips on the length and thickness. Then all chips are crushed and sorted to obtain fractions consisting of acceptable chips in the form separated to the longitudinal fragments, and the fraction containing wood fines and particles of rot.
EFFECT: reduced duration of treatment of wood chips and reduction of power consumption during processing of pulpwood.
