Other raw materials, such as mill scale, shale, bauxite and fly ash, are brought in from outside sources when necessary. Rock blasted from the quarry face is transported to the primary crusher, where chair sized rocks are broken into pieces the size of baseballs. Some plants will use a secondary crusher, depending on process needs.

The process of producing cement starts with the extraction of raw materials in the quarry. This involves the crushing of minerals in the mills, using electric motors. In this way, the clinker is obtained from the kiln. The temperature of this kiln is very high, and this is where industrial process fans are used.

The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.

Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.
