The source of lime for cement making is usually limestone or chalk. As typically 80% of the raw mix consists of limestone, it is referred to as the primary raw material. The secondary raw material, which provides the necessary silica, alumina and iron oxide, is normally shale or clay. Small quantities of sand or iron oxide may be added to adjust the

When working on a 'by volume' basis, allowance should be made for bulking of sand if necessary. Dry material should be well mixed before adding water. 3) Mixing : As much water should be added to the mix as will produce water sheen on the surface of the block, and still not cause the block to slump.

The purpose of optimum raw material preparation for the cement manufacturing process is to supply the downstream burning process with a raw meal whose quality and homo geneity assures the economi cal production of highquality cements.
