steel mill circuit


The crusher in closed circuit is then used to reduce the size of the critical size material and return it to the mill. As the pebble ports also allow steel balls to exit, a steel removal system (such as a guard magnet, Chapters 2 and 13 Chapter 2 Chapter 13) must be installed to prevent them from entering the crusher. (Because of this ...

The first two consist of a spiral rotating in an open steel trough or box set on a slope, the spiral working the sand to the upper end and the slime overflowing at the lower end. Spirals of 8 to 12 inches diameter are available for small plants. The 12-inch size is good for 12 tons a day. A 24-inch spiral will handle 35 tons.

Lime removes impurities (silica, phosphorus, sulfur) from the steel being manufactured. The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel. Lime is also used to enhance the refractory life of the furnaces. The MgO in dolomitic lime reduces the tendency ...

To make steel, it is necessary to oxidize the carbon (as well as other elements like silicon and manganese) out of the melt. This is done in a further steelmaking plant, where pure oxygen is blown into the hot metal through a top lance or bottom tuyeres. The reactor is called a converter or BOF (basic oxygen furnace).

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.
