Installations for processing metallurgical slag dump, INCLUDING SLAG steelmaking

摘要

Use of: processing byproducts metallurgical industry, namely the processing of metallurgical slag dump, particularly open-hearth and steelmaking converter slag, for recovery of these metals. Summary of the utility model: setting processing dump metallurgical slags, in particular slag of steelmaking, comprising means for loading a slag, and at least two series-mounted to the process unit line, each of which comprises a crushing apparatus, the apparatus for classifying by fractions of particles and transport device, wherein the transporting devices are provided for the magnetic separators for selecting ferromagnetic particles of the conveyed raw materials and device oystva for classifying particle fractions formed with cells, the value of which decreases in each subsequent unit. What is new is as crushing device units comprise roller mills with smooth rollers, wherein the gap between the rolls in roller mills each subsequent unit decreases, and the apparatus for classifying cells into fractions of particles greater than the gap between the rollers corresponding to roller crusher unit. New is also that the rollers in the roll mills are set to provide a different speed. New is also that in use as suspended separators magnetic separators; controlled variable magnetic field. The technical result: provision of necessary and sufficient efficiency crushing slag that can improve the degree of extraction of metals from metallurgical slag dump while ensuring high quality of the extracted metal.
