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 raymond mill manufacturer from China. For coal gangue raymond mill, HD series is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
