How To Make Steel Tinkers Construct

How is coal turned into steel? Pig iron is the basic ingredient to produce steel. Coal therefore plays three roles in the production of steel: a reducing agent, to turn the pig iron to coke; a source of energy to drive the process by breaking apart molecular bonds; and a source of carbon for the final product (steel is an alloy of carbon and iron).

Ball Mills - an overview | ScienceDirect Topics

Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steel-alloy balls (also described as charge balls or media) are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing.
