Nov 28, 2015· Mill scale contains iron oxides that can be substituted for other iron-bearing materials when used in the kiln feed. Select types of slag can produce a blended cement product when inter-ground with Portland cement. As a replacement for natural stone as an aggregate, foundry sand and some types of slag can be used in Portland cement concrete.

Thus, a first disadvantage in using mill scale in the production of cement clinkers is the necessity of removing any hydrocarbons that may be present. Further, in the prior art process, as far as is known, when the mill scale is attempted to be used in making cement clinkers, it is first finely ground with the other feed stock materials.

Some typical materials used for silica in cement manufacturing are sand, clay, claystone, shale, slag, and fly ash. Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash.
