As the starting point for power transmission throughout the machine, this shaft is directly connected to the drive system and smoothly distributes power to the other three shafts via precision gears. Its surface features special anti-slip patterns, ensuring initial contact with the material being crushed while receiving power, laying the foundation for subsequent gripping. Maintaining a stable speed during operation ensures uniform power output and prevents load fluctuations from affecting the coordinated rhythm of the other shafts, which is crucial for consistent operation.

Located parallel and symmetrically with the first shaft, this shaft's core function is to work with the first shaft to grasp and secure the material. Its claws mesh with the first shaft's patterns. When material enters the crushing chamber, the two shafts rotate synchronously in opposite directions, using the interlaced motion of the claws to securely clamp the material, preventing it from shifting or slipping during the crushing process. Furthermore, this shaft automatically adjusts its gripping force based on material hardness, ensuring stable retention of materials of varying materials and providing precise positioning for subsequent shearing.

This shaft forms a triangular structure with the first two shafts and features high-strength alloy shear discs. After the material is secured by the first two shafts, the third shaft rotates at a slightly faster speed. The teeth of the cutter discs and the claws of the other shafts intersect, shearing and tearing the material layer by layer. The spacing between the cutter discs can be adjusted according to the crushing requirements, gradually breaking down large pieces of material into fine particles. The rotational inertia of the cutter discs simultaneously propels the initially crushed material toward the fourth shaft, ensuring a continuous crushing process.

As the final step in the crushing process, this shaft is primarily responsible for material diversion and distribution. Its spiral guide structure works closely with the third shaft to quickly transport crushed material to the discharge port, preventing accumulation and blockage within the crushing chamber. Furthermore, this shaft can adjust its speed to control the discharge rate, synchronizing it with the crushing rhythm of the first three shafts to ensure that each batch of material is fully crushed and discharged promptly. In addition, its material guide structure can perform a secondary sorting of incompletely crushed materials to ensure uniformity of the output particles.
