Installations for processing metallurgical slag dump, INCLUDING SLAG FERROVANADIEVYH

摘要

Use of: processing byproducts metallurgical industry, namely the processing of metallurgical slag dump, particularly ferrovanadievyh slag, for recovery of these metals and the use of slag in construction, particularly in the cement industry. Summary of the utility model: dump unit for processing of metallurgical slags, in particular slags ferrovanadievyh includes a receiver, coarse crushing device, the crushing device is finely ground, conveying devices are connected, and metal separators. What is new is that the system further comprises a serially coupled with two fine milling device collecting hopper with a screw feeder with a hopper placed between roll crusher with smooth rollers, wherein the output of each screw feeder installed metal separator, which is used as an electrostatic separator. New is also that the roll crusher is designed to provide varying rotational speed of the rolls, which are mounted with a gap equal to 0.5-1 mm. The technical result: provision of possibilities pofraktsionnogo ferrovanadium extraction of slag, increasing the degree of metal recovery from slag while the slag suitable for use in construction, particularly in the cement industry.
