Installations for processing metallurgical slag dump, INCLUDING SLAG stainless steel production

摘要

Usage: in the processing of by-products of metallurgical industry, namely the processing of metallurgical slag dump, particularly slag in stainless steel production, for extraction of metals. The essence of the utility model: Apparatus for processing dump metallurgical slags, in particular the production of stainless steel slag, comprising a device for charging the slag, magnetic separator for selecting ferromagnetic particles of the transported raw material, and at least two successively set into the process assembly line, each of which consists of a crushing device, a device for transporting the slag, devices for classification of particles into fractions, the apparatus for classifying particles by Fra ktsiyam performed with cells, the value of which decreases from the first unit to the next. What is new is that the system further comprises a metal transport device located at the device output for classification into fractions of particles, wherein as a device for splitting the first unit comprises a jaw crusher, each subsequent unit - two-roll mill with smooth rolls, at what gap between two-roll mills rolls in each aggregate is decreased by one unit to the next, and the magnetic separator installed above the device for conveying the metal. What is new is the fact that in a two-roll mill with smooth rolls one; of the spring-loaded roll and is mounted for oscillation in the horizontal plane, and the second roller is mounted fixedly, and the rollers are arranged to provide different rotational speed. What is new is the fact that as devices for classification using vibrating screens into fractions of particles. What is new is the fact that as a magnetic separator, a separator with an overhead-variable magnetic field. The technical result: provision of necessary and sufficient slag crushing efficiency, which improves the degree of extraction of metals from metallurgical slag dump, particularly stainless steel.
