Causes and Prevention of Cracks in the Crushing Wall

Causes of Cracks in the Crushing Wall

1. Material Defects: During the crushing wall manufacturing process, if the raw materials contain defects such as inclusions, pores, and looseness, these defects will become stress concentration points during use and easily cause cracks.
2. Improper Design: The design fails to fully consider the actual stress conditions of the crushing wall, resulting in excessive stress in certain areas. Long-term uneven stress is prone to cracks.
3. Improper Manufacturing Processes: Improper operation of manufacturing processes such as welding and heat treatment can cause residual stress within the crushing wall, which can cause cracks during use.
4. Overload Operation: Operating the crushing wall beyond its design load can cause material fatigue, and long-term overload operation can accelerate the development of cracks. 5. Wear and Corrosion: During use, the crushing wall is subject to wear and corrosion from materials and chemicals, gradually degrading its surface and internal structure, leading to cracks.

Preventive Measures for Cracks in the Crushing Wall

1. Strict Material Inspection: Before crushing wall production, the raw materials undergo rigorous quality inspection to ensure they are free of defects, thereby reducing the possibility of cracks at the source.
2. Reasonable Design: A scientific and rational design is implemented based on the crushing wall’s operating environment and stress characteristics to ensure uniform stress distribution across all parts and avoid stress concentration.
3. Optimize Manufacturing Processes: Utilize advanced manufacturing processes, such as precisely controlling welding parameters and performing appropriate heat treatment, to reduce residual stress.
4. Control Operating Load: During use, the crushing wall’s load is strictly controlled to avoid long-term overload operation and reduce material fatigue.
5. Regular Inspection and Maintenance: Regularly inspect the crushing wall to promptly detect and address wear and corrosion issues, preventing the initiation and propagation of cracks.
6. Apply a Protective Coating: Applying a protective coating to the crushing wall surface can effectively reduce material wear and chemical corrosion, extending its service life. Conclusion: The generation of cracks in the crushing wall is the result of the combined effects of multiple factors. Through strict material quality control, optimized design, improved manufacturing process, rational use and regular maintenance, the generation of cracks can be effectively prevented and reduced, ensuring the safe and stable operation of the crushing wall and the entire equipment.
