The double-shaft shredder machine is an environmental protection shredder device for solid waste volume reduction, which is composed of a cutter chamber, framework and conveyor. Its dual shafts are independently driven. During production, the motor drives the main shaft of the cutter chamber through the pulley, so that the shredder blade rotates with the blade holder body connected with the main shaft to achieve the feeding function. The different soft and hard scraps waste entering the cutter chamber are shreddered by the shearing, tearing and squeezing between the blades, and then filtered through the bottom of the chamber to drop the materials with the size as required. It is used to shred, shear and squeeze large pieces of material into small pieces of material, which is conducive to material regeneration and recovery. It is used to shred, shear and squeeze large size material into small, which is conducive to material regeneration and recovery.
