Efficient branch crusher set slices, crushed as a whole, can chip 1--20 cm diameter twigs and branches, mainly used for processing pine, hardwood, Jan wood, cedar, bamboo and other raw materials, more suitable for mushroom medium wood machining. Meanwhile, the device can also be used bamboo chips, grass, corn stalks, sorghum stalks and other fibrous stalk-like material. The sawdust and wood chips can also be made of particleboard mill, sawdust board high-density materials production. The equipment for mobile operations, is widely used in small and medium sized enterprises particleboard and fiberboard production preparation section can also be used for the self-employed in the production of goods of wood . Branch crusher works: the use of efficient wood grinder blade cutting and high-speed airflow impact of the collision crushed dual functions in one, and can be completed at the same micro-material sorting and processing operations. In the process of crushing the cutting blade, rotor speed airflow generated, with the direction of rotation of the cutting blade, the material in the gas stream to accelerate and repeated impact of materials while being double smash, smash rate accelerated material.
