Abstract

This invention relates to the field of crusher technology, specifically proposing a crusher for smelting magnesium using the silicothermic process with electric furnace slag. It includes a protective cover placed on the ground for external protection. Inside the protective cover are two crushing rollers for crushing raw materials. Outside the protective cover are a drive mechanism for driving the two crushing rollers to rotate relative to each other. Inside the protective cover are two sets of feeding mechanisms for guiding the raw materials to the area directly above the two crushing rollers. Each feeding mechanism includes a rotating shaft rotatably mounted inside the protective cover. The raw material first falls from an extension tube onto a reinforcing plate. Then, the raw material between the reinforcing plates slowly feeds from a position near the top of the crushing rollers as the rotating shaft rotates. Compared to the conventional method of feeding from above, by reducing the material's fall height twice, the impact force on the crushing rollers is reduced, not only avoiding stone splashing but also extending the service life of the crushing rollers.
