In the operation of environmental recycling equipment, the adaptability of wear parts directly determines processing efficiency. Jiangxi Mingxin, focusing on equipment R&D and accessory manufacturing, has developed shredder blades and crusher hammers with distinct characteristics based on the different operational requirements of shredders and crushers. These two types of parts have different focuses in design, material and function, which accurately meet the operational requirements of the entire coarse and fine crushing process.
In terms of structural design and working principle, Mingxin shredder blades are mainly for shearing and tearing functions. Single-shaft models adopt rhombus blade bodies, while multi-shaft models are equipped with 3-claw, 8-claw and other claw knife designs. The blade bodies have arc or tooth-shaped structures. Through the low-speed and high-torque biting action, they tear large pieces of high-toughness waste materials such as plastics, rubber and wood into irregular blocks, easily handling difficult-to-process materials like bundled films and machine head materials to avoid jamming. Crusher hammers are mainly hammer-type structures with plate-shaped rectangular bodies, some of which are designed with surfacing wear-resistant layers. They rely on the inertial impact force generated by high-speed rotation to strike, knead and finely cut the shredded block materials, refining them into uniform small particles below 20mm, which meets the process requirements of subsequent cleaning and granulation.
For material selection, both follow the principle of adaptability and select high wear-resistant and durable raw materials. According to the operating scenarios, Mingxin shredder blades use alloy tool steels and cold work die steels such as 9CrSi and Cr12MoV. Blades made of Cr12MoV have both high wear resistance and impact resistance, suitable for shredding high-hardness materials. Crusher hammers are based on medium carbon steel and special cast iron, with key working corners surfacing tungsten carbide alloy. They feature hard surface and tough inner layer, which are wear-resistant and not easy to break during high-speed impact operations. In addition, their four corners can be rotated for use, extending the single service cycle.
The differences in application scenarios and operational positioning are more significant. Mingxin shredder blades are the core of the coarse crushing link of the equipment, suitable for the initial decomposition of large, irregular and high-toughness materials, and are the first key process for waste volume reduction, widely used in coarse crushing production lines for solid waste recycling. Crusher hammers focus on the fine crushing link, only performing refined processing on shredded block materials, and are essential components to standardize material particles and adapt to subsequent deep processing. The combination of the two can form a complete "coarse crushing-fine crushing" operation process, greatly improving the overall production efficiency.
As the exclusive supporting wear parts of Jiangxi Mingxin equipment, both shredder blades and crusher hammers have undergone strict heat treatment and precision testing. The dimensions of the blade bodies and hammers perfectly match the equipment without adaptation deviation, and their wear resistance and impact resistance are far superior to general-purpose accessories. They not only ensure the stable operation of the equipment, but also reduce the cost of later replacement and maintenance. Choosing the right core wear parts makes environmental recycling operations more efficient. With professional accessory manufacturing, Jiangxi Mingxin provides a strong guarantee for the continuous and efficient operation of equipment.
