They need to be crushed before recycling, and the crushing device used for metallurgical slag treatment is usually a mechanical equipment, called a crusher or a crusher. They can be selected according to the characteristics of the slag and the processing requirements. For example, metal slag can be treated with a metal crusher, while non-metallic slag may require different types of crushers to process.
