Description
Technical Field
[0001] The utility model belongs to the technical field of anthracite processing, and in particular relates to an anthracite impurity screening device used for calcium carbide production. Background Art
[0002] Anthracite is used as raw material in the production of calcium carbide. Anthracite is commonly known as white coal or red coal. It is the coal with the highest degree of coalification. Anthracite has high fixed carbon content, low volatile matter yield, high density, high hardness, high ignition point, and does not smoke when burning. It is black and hard with a metallic luster. Anthracite is made of high-quality raw coal as raw material, which is selected, crushed and screened.
[0003] The existing anthracite impurity screening equipment is not equipped with a hot air device. The wet coal in the anthracite is easy to agglomerate, which is not convenient for screening impurities, affecting the screening quality and causing economic losses. In addition, the traditional anthracite impurity screening device can only filter out impurities with larger particle sizes in the anthracite during the impurity screening process. It is difficult to clean out the relatively fine impurities mixed on the surface and inside of the anthracite, resulting in poor screening effect. For this reason, we propose an anthracite screening device to solve the above problems. Summary of the invention
