There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

Limestone Quarrying: The first step in the limestone processing process is quarrying. Large limestone deposits are extracted from quarries using heavy machinery, such as bulldozers and excavators. These machines strip away the overlying soil and rock layers to expose the limestone deposit, which is then drilled, blasted, and extracted. Crushing ...

Limestone is a rock composed of calcium carbonate (CaCO 3 ). It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock. Limestone can be used to make cement.

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
