ERGA RESOLINE — kompleks za čeličnu šljaku

Kompleks drobljenja i sitarenja za reciklažu čelične šljake sa izdvajanjem metala.

• Industry: recycling, ferrous metallurgy, nonferrous metallurgy
• Problem description: Recycling of waste stockpiles with subsequent return of metal concentrate into production is an actual task for smelters. Unlike the technologies of past decades, modern complete solutions provide feasible recovery of metals from slag, turning waste into a profitable source of recyclables. Contacting ERGA to solve his problem, based on the calculations, the results of laboratory tests and reliable justifications, the Customer made a reasoned decision to build a modern crushing and screening complex on the site of his slag stockpiles. With the help of the new plant, it is planned to process all the slag (about 8 million tons) accumulated for over 80 years of the enterprise's production activities within the coming 10 years. Automatic turnkey complex solution
• ERGA accomplished a full range of services from design to installation and commissioning of crushing and screening complex for processing of steel slag on the territory of the Customer's landfill.
• All separators in the line are equipped with automatic cleaning system and provide recovery and cleaning of scrap, which is suitable for further melting in steel furnace. The entire process can be controlled by one operator with the control panel. Monitoring of critical points can be via video conferencing at the operator's site or remotely via Internet.
• As a rule, the issue of magnetic separation is not given sufficient attention in conventional crushing and screening plants, and manufacturers of crushers select the separators. From their point of view, the more powerful the magnet is, the better, which is a key mistake. "Strong magnet" will extract even weakly magnetic fraction from the input, as a result, there will be a significant contamination in the magnetic fraction.
• How to choose the magnetic field strength? ERGA experienced specialists deal with this issue, developing not a product, but a complex for slag processing, selecting the most efficient process for the raw material and with lower expenses for producing the end products required by the Customer.
• An atypical approach to slag cleaning was applied in this project, since the input after magnetic separation is fed into the crusher; the magnetic component is cleaned from impurities to pure metal in several stages. Multi-stage crushing of slag combined with magnetic separation provides maximum clean metal output, metal concentrate with iron content over 80%.
