Abstract

The article examines issues of rational use of natural resources in relation to the forest industry – stump wood, slabs, branches, tree tops. Particular attention is paid to the issue of processing low-quality wood into chips in rosin and turpentine production, where sorting chips and particles of wood materials by resin content plays an important role at the production stage. A method for sorting chips and particles of wood materials by resin content in an electrostatic field is considered. When reviewing existing designs, their shortcomings were identified, the main ones being the low efficiency of the wood separation process and high electric field strength. The author proposed a new design of a sorting device for technological chips in order to increase the efficiency of separating wood particles in an electrostatic field by resin content. A distinctive feature of this design is that the materials are charged on the conveyor when they are fed into the electrostatic field of the separator. The proposed design of the sorting device allows to increase the efficiency of the wood particle separation process and reduce the electric field intensity. An experimental setup has been created and initial studies have been conducted.
