steel production are slag (90% by mass), dust and sludge. Process gases, for example, from the coke oven, BF or BOF are also important coproducts. However, this fact sheet will mainly focus on solid coproducts. On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of coproducts. These include slag, dust, sludge and other materials. Ironmaking and ...
· Ball mills use a tumbling process with stone or metal balls as the grinding materials to reduce the coarse material by means of impact and friction. Ball mills typically use water or other liquid and additives to help reduce friction and provide cooling during the grinding process. The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from ...
