Working principle of double-shaft shredder
As an efficient material crushing equipment, the working principle of double-shaft shredder integrates scientific principles such as mechanical transmission, knife shearing and material deformation under stress to achieve effective crushing of various complex materials.
In terms of power source, the double-shaft shredder is equipped with a specially designed motor. As the power core of the entire equipment, the motor can stably output powerful electrical energy and efficiently convert it into mechanical energy. This mechanical energy is transmitted to the key operating component inside the equipment-the knife shaft through a carefully designed transmission device, such as a belt, chain or coupling.
Two knife shafts that are parallel to each other and rotate at high speed in opposite directions are set inside the double-shaft shredder. These two knife shafts are the core executive components of the entire working principle. The knife shaft is usually made of high-strength high-quality steel, and the surface undergoes a special heat treatment process. It not only has good toughness to resist the impact during operation, but also has extremely high hardness to ensure that it will not be easily deformed or damaged under long-term high-intensity working conditions.
Specially designed blades are evenly distributed on the knife shaft. These blades are key components that directly act on the material. They are mostly made of high-hardness, wear-resistant and corrosion-resistant alloy steel. The shape of the blade is designed in a variety of ways according to different material characteristics and crushing requirements. Common ones include square, triangle, toothed, etc. The gap between the blades is accurately calculated and debugged to ensure the best material crushing effect during operation.
When the material is fed into the crushing chamber of the double-shaft shredder, first, the high-speed rotating knife shaft drives the blade to rotate quickly, generating a strong shear force. Under the high-speed staggered movement of the blades, the large pieces of material are quickly cut into smaller pieces, just like being cut by scissors. As the knife shaft continues to rotate, the material fragments are constantly squeezed between the blades and between the knife shaft and the wall of the crushing chamber. This squeezing comes not only from the direct pressure of the blade on the material, but also from the mutual squeezing of the material in a small space when the knife shaft rotates. Under the strong squeezing force, the material fragments are further compressed and deformed, the internal structure is destroyed, and the volume continues to decrease.
For some materials with strong toughness, simple shearing and squeezing may not be enough to crush them completely. At this time, the tearing effect of the blade plays a key role. The sharp edge of the blade can penetrate into the tough material, and the rotation of the blade shaft drives the blade to continuously pull the material, so that the material is torn along the weak parts inside, thereby achieving effective crushing of such materials.
During the entire working process, the control system of the double-shaft shredder will monitor the operating status of the equipment in real time, including parameters such as the motor current, the rotation speed of the blade shaft, and the material conveying volume. Once an abnormal situation occurs, such as material blockage causing motor overload, the control system will respond immediately, adjust the output power of the motor, or reverse the blade shaft briefly to eliminate the fault, ensure that the equipment can continue to operate stably, and efficiently complete the material crushing task.
