The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.

Dec 01, 2006· In order to produce raw materials preparation, clinker and rotary kilns are widely used in cement plants. The objective of this study is to perform energy and exergy analysis of a raw mill (RM) and raw materials preparation unit in a cement plant in Turkey using the actual operational data. The RM has a capacity of tonmaterial hourly.
and an integral separator with industryleading efficiency, the mill consistently uses five to ten percent less power than other cement VRMs. This productivity benefit amounts to millions of kilowatts saved annually for OK mill owners. The OK raw mill is designed according to the same design principles.
With dust chemistry varying between direct operation when the raw mill is out of action and indirect operation when the raw mill is running, finding a destination for baghouse dust while maintaining a homogenous kiln feed is a longstanding issue in cement production.
