Industrial Raw Materials

MILL SCALE A byproduct of the steel manufacturing industry mill scale has many industrial uses as a raw material It consists of oxides of iron that form on the surface of hot metal during processing While the steel is very hot it picks up oxygen from the air and forms a thin crust As the steel is stretched and shaped the thin crust falls

The principal raw material required for cement manufacturing is Limestone Limestone is mined from the mines by blasting explosives and is transported from the mining area to the process plant and then fed into a primary hopper from where the limestone bolder is fed to the primary crusher (Jaw Crusher) with the help of a reciprocating feeder The crushed limestone pieces are discharged to the

raw materials for Portland cement clinker production Two di erent kinds of alumina-silicate material (clay and IOT) were used in the experiment e calcareous material was limestone Quartz sand and iron ore were used as corrective materials to adjust the contents of silicate and iron of raw meal respectively e main chemical composition of


Cement Clinker crushing and grinding Plant

Cement Clinker's Wet Process In the wet process each raw material is proportioned to meet a desired chemical composition and fed to a rotating ball mill with water The raw materials are ground to a size where the majority of the materials are less than 75 microns Materials exiting the mill are called "slurry" and have flowability

Fuzzy controller for cement raw material blending

The main goal of raw material mill blending control in the cement industry is to maintain the chemical composition of the raw meal near the reference cement modules for the kiln at a desired value with minimum variance despite variations in the raw material composition Because of the continuous variations in the chemical composition of the raw materials one cannot work with a fixed blending
