For grinding,xhard coal, lignite, coke, petroleum coke and sewage sludge, xclay, limestone, burnt lime and raw phosphate The Polysius Research and Development Centre uses the test-roller mill Atrol (throughput approx. 240 kg/h) for grindability testing and quantitative prediction of wear in industrial mills. Roller mill for granulated blast furnace slagUS mini-mill costs drop below integrated mill costs…but,,US mini-mills are typically higher cost. On an operating cost basis, US integrated mills are typically lower cost than their mini-mill peers. Scrap prices are tied to the marginal cost of hot metal production—meaning that the input for scrap-based steelmaking is typically higher than the average ironmaking bulks mix (n.b. iron ore, coal and coke).
