[0002] In existing technologies, raw material screening and crushing devices for processing have some operational inconveniences and design deficiencies in practical applications, especially in terms of the replacement and maintenance of the crushing die. The crushing die is one of the most important components of the device, and its function is to refine or screen the raw material into the required granular or powdered form during the crushing process.

[0003] First, the shredder is usually installed inside the equipment using bolts, screws, and other fixing devices. While this fixing method ensures the stability of the shredder to a certain extent, it also leads to the complexity of the replacement process. During replacement, operators need to use a large number of tools to disassemble a large number of bolts or other fixing parts. This process is not only time-consuming and labor-intensive, but may also cause difficulties in disassembly or damage to the equipment due to the loosening or corrosion of parts after long-term use. It also increases the labor costs and the possibility of errors in the production process, affecting the stability and efficiency of production. In addition, excessive manual operation also brings safety hazards, because operators are easily injured by high temperature, high pressure, or mechanical parts during disassembly and replacement.
