Problems solved by technology
[0002] At present, the known grinding equipment for metallurgical steel slag usually adopts the grinding process equipment with ball mill or tube mill as the core equipment. Since the metallurgical steel slag contains solid metal components, it is extremely difficult to grind, resulting in energy utilization of the grinding operation. The efficiency is extremely low, and the output is also low; in recent years, production process equipment composed of roller presses and ball mills has also been adopted. Although the energy utilization rate has improved, this process and its equipment are relatively large and complicated, and it is not easy to install and manufacture. And the investment cost is higher

The invention belongs to a milling production line of steel slag micro powder. The invention is characterized in that the milling production line is arranged according to a steel slag micro powder process flow; the milling production line mainly comprises a raw material hopper, a weighter, a belt conveyer, an iron remover, a metal detector, a three-way material dividing valve A, a horizontal typeroller mill, a dump bin, a hoister, a three-way material dividing valve B, a powder concentrator, a powder return belt conveyer, a magnetic separator, a metal bin, a temporary material hopper, a finished powder collector, a fan, a regulating valve and a finished powder collecting library. The invention has reasonable design and compact structure, improves the production efficiency and the steel slag milling quality, overcomes the defect of low energy utilization ratio of a ball mill, solves the problem of complicated process flows of a roll squeezer and the ball mill and ensures that the milling process is simple and easy to apply. In addition, metal in the steel slag is sorted out through the magnetic separator after the metal is milled and then renewedly subjected to steel making, thus the economic value is high, and the production line has the advantages of energy saving, convenient mounting and manufacture, small occupied area, low investment expense, convenient operation and use, and the like.
