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.

There are four main raw materials used to make glass: silica sand, soda ash, dolomite and limestone. In many cases, broken pieces of glass called cullet are also added to these raw materials to help them properly melt when heated. There are a number of different ways to make glass, depending on the desired finished product.

1 Sand, soda lime, and crushed cullet are fed into a large, furnace-driven tank. In the tank, the mixture is heated to 2300°F (1260°C) to melt the raw materials. This can take as long as 28 hours. Injection 2 Next, the molten mixture moves out of the tank through an opening into another vat known as the flow tank.

They can be used less or not under certain conditions. The rational use of recycled materials can save some raw materials and help reduce production costs. Silica sand is one of the main raw materials for the production of silicon carbide, which is processed from natural silicon-containing materials. Its main component is silicon dioxide SiO2.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
