The production process for cement consists of drying, grinding and mixing limestone and additives like bauxite and iron ore into a powder known as "raw meal". The raw meal is then heated and burned in a preheater and kiln and then cooled in an air cooling system .
Steel production requires iron, steel scrap and lime (burnt limestone). The iron ore is smelted to produce an impure metal called "hot metal" when in liquid phase or "pig iron" when in solid phase. In smelting, a reducing agent usually coke and heat are used to remove oxygen from the metal ore.
Its main contents include hematite, ilmenite and ferrous manganese ore, sizes are around 10000 mesh. In oil industry, it's used cooperatively with iron ore powders of 1200 mesh and 250 mesh, through grain composition effect, to modify cement density and increase the suspension stability of high temperature and high density slurry system.

Cement Industry Safety Topics. To produce cement, limestone, clay, sand, iron ore and sometimes industrial waste such as oil shale and coal fly ash are ground in a rotary kiln, heated to 2,462 degrees Fahrenheit and cooled. The final product, clinker, is mixed with gypsum and silica powder to .
In the US, LafargeHolcim has 13 plants that produce more than 22 million tons of cement every year, as well as two grinding stations out of which we sell fly ash and slag. From our quarries, limestone and other raw materials are mined and then processed at the plant through a series of crushing, grinding and firings in our kilns, in which temperatures reach up to 2700 degrees Fahrenheit.
