To make Portland cement, clay, shale and limestone is ground to a powder and baked in a kiln. The baked mixture forms clods (clinkers), which are then ground up and mixed with gypsum. Most of the raw materials are mined in open pits. Michigan traditionally ranks in the top five states in terms of cement production.

Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versa- tile commodity. Portland cement is essential to the building industry, but despite our Nation's abundance of limestone, there have been cement shortages in recent years.
Cement manufacture, like many other manufacturing processes, begins at the mine, where the raw materials like limestone, silica, aluminates, feric minerals and others are obtained. Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell.

Mining Methods. "Most California limestone and dolomite deposits are situated on hills where they can be readily quarried from level benches cut into the hillsides. In some places, however, it has been necessary to utilize pits sunk well below local base level, with resultant higher quarry costs. There are four large, and one small ...
Cement Manufacturing Process The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers.
Precision drying and grinding in a single step Thoroughly dry limestone is critical for fine grinding. With heating and grinding combined in a single operation across most models, our Raymond roller mill installations are perfect for the job, delivering exactly the right degree of fineness required for your end application.

Limestone Mining. LIMESTONE MINING. Calcite and dolomite, when heated and in some cases slurried or combined with salt, are used in making many everyday products such as paper, glass, paint and varnish, soap and detergents, textiles, refractories, baking powder, and pharmaceuticals, including milk of magnesia and bicarbonate of soda.
The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.
For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant.
