Raw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1. Limestones: These are sedimentary, calcium carbonate rocks (CaC0 3 ). Most commonly they contain a small amount of magnesium carbonate also.
Cement plant is necessary for cement production, mainly consist of a series of cement equipment apply for preparation of cement raw materials, clinker production, and finished cement production, such as cement mill, cement crusher, rotary kiln, cement roller press, cement dryer, clinker cooler, cement silo, and related cement plant equipment.

Raw Mill In Cement Plant,Cement Making Plant. This paper mainly introduces the raw mill in cement plant In order to achieve the desired setting qualities in the finished product, a quantity (28%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder This is achieved in a cement raw mill
Raw Mill In Cement Production. With consistency of raw mix process stability is easier to maintain enabling production levels to be maximised without risking equipment damage Overburning of clinker is also avoided resulting in a more grindable product and lower electricity consumption in the cement mill and fuel and energy inputs into a stable system are also lower.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

The CCG is a smallscale grinding plant designed to produce different types of cement. At its heart – LOESCHE's wellproven, stateofthe art LM CS vertical roller mill. From the feed hoppers, clinker or slag is conveyed to the mill, with the finished product being separated in a highefficiency classifier and collected in the baghouse ...
Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and is of predominantly fine grained crystalline structure, its hardness is between to of the Mohs scale of hardness and specific gravity 2. To Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.
In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.
Cement Raw Mill. Cement kilns raw material preparation preparation of cement raw materialpressing the chemical analyses in the way usual in the cement industry, he next logical step was to simplify the above system by combining the ball and tube mill functions into a single mill tube.
· 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.
