This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, 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.

In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.
2. Fineness & Homogenization of Raw Meal The fineness and homogenization of raw meal have an important impact on the clinker quality. Generally speaking, the fineness of the raw meal needs to be contained between 12% and 16% to ensure the quality of the product clinker.
Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to be ground into the final product.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
Portland cement clinker is nodules (diameters, 5–25 mm) of sintered material produced by heating a homogeneous mixture of raw materials in a kiln to a sintering temperature of approximately 1450 °C for modern cements. The resulting clinker consists of …

The plant average raw meal to clinker ratio is 1.59. The average total renewable and non-renewable primary energy required to produce a metric ton of clinker was calculated to be 3.88 GJ on a lower heating value basis. Table 2. Clinker production technologies applied in the making of the portland cement described by this EPD.
In this step, raw materials should be fed into the crushing mill to reach an appropriate granularity, and then be homogenously stored in the steel silo for further processing. Raw material proportioning and grinding is the second step, in which the manufacturer will prepare the raw mix according to the requirements of clinker ingredients ...
