High-Temperature Material Crusher: A Solution for Special Working Conditions of Metallurgical Slag and Chemical Raw Materials

In industries such as metallurgy, chemicals, and building materials, there is often a need for immediate crushing of special high-temperature materials such as furnace slag and high-temperature sintered materials. These working conditions place stringent requirements on crushing equipment, demanding extreme heat resistance, oxidation resistance, thermal shock resistance, and continuous reliable operation. Specialized crushers provide safe and efficient solutions through innovative integration of materials science, structural design, and cooling systems.

Core technologies focus on high-temperature resistant materials and adaptable structures. Key components of the crusher that directly contact the material, such as hammers, liners, grates, and rotors, are generally made of high-chromium wear-resistant and heat-resistant cast iron, tungsten-titanium alloy composite casting, or special ceramic materials. This ensures that sufficient high-temperature hardness, oxidation resistance, and thermal fatigue resistance are maintained even when continuously contacting materials at temperatures of 800°C or higher. The main structure of the equipment requires thermal expansion compensation design, such as using floating bearing seats and reserving thermal expansion gaps, to prevent structural deformation and jamming caused by high temperatures. Feeding devices are often equipped with water-cooled jackets or heat-resistant alloy chain curtains, which both block heat radiation to protect upstream equipment and pre-cool the material.

Active cooling systems and intelligent monitoring provide dual guarantees for stable operation. For continuous high-temperature conditions, the crusher integrates forced air cooling, water-cooled jackets, or spray cooling systems to provide targeted heat dissipation to critical areas such as bearing housings, housings, and rotor shafts, controlling the operating temperature within the allowable range for materials and lubricating oil. Simultaneously, it is equipped with online temperature and vibration monitoring and alarm systems to monitor equipment status in real time. In case of overheating or abnormal vibration, it can automatically issue warnings or even shut down the machine to prevent damage from overheating.

Application scenarios and selection criteria are highly specific. This type of equipment is designed specifically for processing materials such as metallurgical blast furnace slag, steel slag, calcium carbide slag, high-temperature clinker, and recycled aluminothermic ash. When selecting a model, precise material characteristics (temperature range, particle size, abrasiveness, viscosity) must be provided to determine the appropriate model (such as a high-temperature hammer crusher, jaw crusher, or roller crusher), cooling scheme, and wear-resistant material grade. Successful application not only enables the resource-based and immediate processing of high-temperature materials, improving the continuity and automation level of the production line, but also significantly improves work safety and working conditions in high-temperature and high-dust environments.
