Sorting solution removes copper meatballs in ferrous streams, increases purity of scrap
The purity of iron scrap is crucial for sales in the steel industry. Operators of shredder plants using the STEINERT SteelMaster can now reliably undertake physical separation and free their ferrous streams of copper meatballs.
Mainly handpickers are separating copper meatballs and free copper content from iron. With hundreds of objects passing over the sorting belt every second, it isn't easy for the handpickers to find and sort these problematic items, especially as they may be large or small, solid or weighty. The purity of the ferrous product may therefore vary greatly, making the product harder to sell. By deploying a combination of ballistic and magnetic effects, the new STEINERT SteelMaster is a good and efficient addition for reducing the amount of manual work needed.
Following the tried and tested electric magnetic drums for recovery and initial cleaning of the ferrous fraction, the use of downstream magnets results in greatly improved quality and much less manual sorting. Based on customer feedback and adapted to the tough conditions experienced in shredder plants, the device has been redesigned. For example, the mechanics of the belt section have been changed to improve material flow and separation properties, simplify maintenance and reduce the copper content in the iron to < 0.2 %. The robust design, typical of Steinert, stands for a long service life and good availability of the technology. The common grain sizes are 20 - 400 mm with high sorting efficiency. The throughput of 75t/h per metre machine width depends on the material composition.
