As efficient waste shredding equipment, the two shaft shredder is widely used for processing plastics, metals, rubber, and electronic devices, offering significant advantages. Its simple working principle allows it to meet the requirements of different materials.
The materials are first delivered to the shredder's intake port via a conveyor belt or the gripper. After entering the shredding chamber, the materials are grasped and fragmented by rotary cutting blades mounted on two counter-rotating shafts. Blades are typically fabricated from high-strength, wear-resistant metals. The counter rotation of the shafts generates substantial shear, tensile, and compressive forces. These mechanical forces progressively reduce the materials to smaller pieces. As a result, the shredder can efficiently process waste with varying hardness, dimensions, and geometries.
To ensure the materials are shredded to the required size, the two-shaft shredder is equipped with a screen mesh. After being shredded by the blades, the materials will be discharged through the screen mesh, and the screen mesh aperture is adjusted according to the shredding requirements. The screen mesh’s function is to control the final particle size of the material and ensure the accuracy of the crushing effect.
The power system of the double shaft shredder is driven by a motor, and the power is transmitted to the knife shaft through a reducer. The function of the reducer is to convert the high-speed rotation of the motor into the low-speed, high-torque rotation required by the knife shaft, thereby ensuring a smooth, efficient shredding operation.
In conclusion, the two-shaft shredder works through the shearing and tearing actions of its blades. The screen mesh controls the particle size. This device efficiently crushes waste and is essential for modern waste treatment and resource recycling.
