[0002] In the coal handling and processing industry, especially in the production of sintered coal, raw coal is often mixed with iron and steel debris. If these iron and steel debris are not effectively removed, they will cause severe wear and even damage to key components such as crusher blades and screens during subsequent crushing and screening processes, leading to frequent equipment failures, affecting production efficiency and product quality, and also increasing the company's maintenance costs and production safety risks.
