This product can crush wood with nails and wire. It breaks the traditional mode of process structure and adopts chain plate type intelligent feeding, which can automatically adjust the feeding speed according to the load of the main motor. The machine runs at full load and avoids running empty. It makes the material more smoothly and increases the production capacity significantly. The machine can be used to catch the material, the automation level is high, the material is directly caught into the conveying platform for crushing, the production process can be operated by only one person; the design of the machine, shorten the material in the crushing chamber stagnation time, improve the service life of wearing parts
