For all dry grinding applications, cement production is certainly the most important. Grinding mill in cement production is to produce limestone or other raw materials to about 90% passing 90 microns in a dry circuit. Grinding occurs at the beginning and the end of the cement making process.
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.

11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
Cement manufacturing process & what is cement made of, it can be discussed conveniently under two headings: Selection of Raw materials and manufacturing methods. 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).
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.

It's a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, ore dressing of ferrous metal and non-ferrous metal, etc. Do your know how does the raw mill work in the cement plant? This paper mainly introduces the raw mill in cement plant.
The proportional ratio of the raw materials is fixed using raw mix design and is determined from the chemical analysis of the raw materials. The raw materials stored in individual feed bins are proportionally delivered through weigh feeders at the discharge of the bins to a belt conveyor or a feeder feeding the mill for subsequent drying and ...
Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.
