Coal gangue is the solid waste discharged during the coal mining process and coal washing process. It is a kind of dark gray rock with low carbon content and harder than coal, which is associated with coal seam during the coal formation process. Coal gangue can be used for power generation, can be used to make building materials such as cement, and can also produce chemical products such as ammonium sulfate.

Guilin hengda mining machinery Co., Ltd is a professional ultrafine mill manufacturer from China. For coal gangue ultrafine mill, HGM series is a good choice, not only for its factory price, but also multiple layers of multiple grinding roller, grinding wheel bracket with a combination of structure, the drive spindle is s multi-angle diamond-shaped structure, crushing power strong, less maintenance, easy demolition, low cost, and the finished product does not turn back.

HGM multi-layer curved roller mill is the ideal equipment for the current dry production of non-metallic mineral powder. Main Unit equipped with built-grading institutions, grading wheel unique structure, grading effect, powder particles concentrated, no large particles of pollution. Grinding ring with a special wear-resistant alloy steel or high chromium manufacturing, life increased by 2-3 times. Main unit base with the overall cast steel structure, high structural strength, shock absorption performance.
