[0003] As a common waste resource, if tree roots are not processed in time, it will not only pose safety hazards, but also cause resource waste and environmental pollution problems. Currently, tree roots are widely used as biomass fuels by enterprises. However, large tree roots cannot be directly put into boilers for full combustion and need to be cut into wood chip fuels. The existing equipment for cutting tree roots has low efficiency, high cost, and a large amount of impurities in the cut tree roots. Moreover, stones or metals mixed in the tree roots will damage the cutting equipment. Therefore, there is an urgent need for a method that can efficiently pulverize abandoned tree roots, convert them into renewable wood chip fuels, and reduce the damage caused by the pulverizing equipment during the process of pulverizing abandoned tree roots, so that the abandoned tree roots can be better recycled, saving resources and reducing environmental pollution Summary of the Invention
