The residue after ore beneficiation or smelting is called slag. The time when slag was discarded is long gone. In the processing and utilization of turning waste into treasure, the charm and role of slag have been deeply excavated. It has shined in China's industrial production, cement production and new energy production, achieving a gorgeous turn of slag slag ultrafine mill deep processing. The deep processing of slag requires the support of processing machinery and equipment. The so-called wool comes from sheep. The source of slag comes from various mineral resources. Therefore, it has trace elements such as calcium oxide, aluminum oxide, and silicon oxide. Processing of equipment such as powder mills, combined with its own performance structure, can bring effective economic benefits. Therefore, processing equipment such as slag crusher and slag mill has appeared in the market. The slag crusher is processed according to different models, with an output of 3-60 cubic meters per hour, the fineness of the finished product is between 30 mesh and 900 mesh, and the proportion of the space occupied by the equipment is small. It is mainly used for processing in the cement industry. . The small equipment of the slag mill has an average heavy industry diameter of 800mm, an output of 0.4-4.5 tons per hour, and a space area of ​​13.9x4x6.2 (m). It is mainly used to develop the use of new energy. The slag is ground separately, and then mixed with the fine powder of clinker and gypsum to form cement. However, because the slag is easily concentrated in the coarse powder when it is ground using a kind of grinding technology, it only serves as a mixed material. Blast furnace slag can also be used as raw materials for cast stones, glass-ceramics, fertilizers, enamels, ceramics, etc. Special attention is paid to the fact that slag is not suitable for long-term storage due to its own hydraulic properties.
