Description

The invention relates to methods for processing technological raw materials from logging waste, further processing to produce technical greens and raw materials for the pulp and paper industry and pyrolysis production and can be used in forest industry enterprises.

The aim of the invention is to increase productivity and quality by allowing for debarking of the branches.

The drawing shows a diagram of the implementation of the method option.

The proposed method is carried out as follows.

Crushed logging waste is fed through the hatch 1 into a closed cylindrical volume 2. In this volume, for example, the rotor 3 rotates at a high frequency, creating a centrifugal airflow. The branches 4 captured by the air flow collide with

This cylindrical volume, the longitudinal axis of which is inclined to the horizon, is removed through the hatch 7. Greens and bark are removed from the closed volume through the nozzles 8.

The use of the proposed method provides a better performance by maximizing the use of the working volume with simultaneous high-quality waste treatment by ensuring the debarking of the branches.
