This equipment mainly consists of feeding silo, crushing double rod, power distribution control system, discharge conveyor, and power drive; Feed silo: Place materials to be crushed to prevent accidents caused by material splashing during crushing; Crushing double series: The double rods are equipped with wear-resistant knives, and all the knife discs are assembled to form spiral knives. After rotation, each knife disc is ensured to be evenly stressed, and the double rollers are buckled to ensure that there are no large gaps between the double series knife discs. The wood is broken through the hook deflection of the knives and the compression between the double rods; Power system: The feed is driven by a reducer.
