The Turkey-based steelmaker Tosyali has purchased a Danieli Lynxs DCR 2227 shredder for the steel company’s Oran, Algeria, facility from Danieli Centro Recycling, an equipment company headquartered in Buttrio, Italy.
According to Danieli, the sale marks the first partnership between Danieli Centro Recycling and Tosyali, one of Turkey’s largest private iron and steelmakers.
The Oran, Algeria site produces more than 1 million metric tons of liquid steel per year from its electrical arc furnace (EAF). The arrival of the shredder is expected to improve profit yields through greater flexibility on scrap purchasing and a reduction in furnace transformation costs, Danieli says.
Davide Braga, executive manager of technical sales at Danieli Centro Recycling, describes the company’s experience as a steelmaker as crucial to the sale. “The most famous Danieli slogan sums it up perfectly: We know the art of steel. We know exactly what a steelmaker is looking for in a product. We are not only selling recycling equipment, we also provide added value in terms of know-how.”
The DCR 2227 shredder is a 4,000-horsepower machine that offers an output of up to 100 metric tons per hour and a yearly capacity of up to 400,000 metric tons of shredded scrap. Standard features that are included with the shredder are its high inertia, long-life, enclosed and capped rotor; heavy-duty rotor bearing housings; and a single unified base structure to increase strength in the vicinity of the anvil, Danieli reports.
The company says the shredder offers lower kilowatt-hour power consumption per metric ton produced. Furthermore, Danieli Lynxs has developed a new hammer pin puller designed to cut maintenance time and the need to replace expensive parts.
Braga says that flexibility in terms of feedstock purchasing is the greatest benefit of the shredder.
“When a customer invests, they want to know how soon they can recover outlay costs. In general, when producing one ton of steel with an electrical furnace, 80 percent of the total production cost comes from the cost of raw materials. Sourcing less expensive scrap, shredding and raising the quality of your final product therefore impact enormously on profitability.”
Braga says adding a shredder allows steelmakers to source less expensive feedstocks and to produce fresh scrap, compared with imported material which may have lost yield through oxidization during storage or transport. Density is another issue, he says.
“Our technical team recommends a density of between 0.9 and 1.1,” adds Braga. “If the material becomes too dense, it can lead to inclusions within the scrap. A more open feedstock will have a higher heat exchange, which results in a shorter melting time.”
Braga says all of the considerations are important factors in the design of the mill as well as of the grids and hammers. “Our dedicated research and development team has produced a range of grids and hammers to suit all applications, and thanks to our subsidiary Danieli Riverside Products, which supplies spare parts, Danieli Centro Recycling is able to apply its experience in shredder consumables to each sale.”
Danieli Centro Recycling currently operates four shredders across Africa and three in the Middle East.
