The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.
Aug 11, 2019· Different manufacturing techniques will use either wet or dry grinding, but each cement manufacturing process will culminate in heating and fine grinding to finish the product. Preparing the raw materials is often the first step in the cement manufacturing process, and involves mining the limestone or obtaining safe industrial waste products.
Cement manufacturing is a very energy intensive process. As such, on-site power plants are increasingly being used to meet energy demands of the cement plant. Some of the fire hazards associated with on-site power plants include fire in power house buildings due to ignition of lube oil.

Dust emission from cement kilns can be a serious nuisance. In populated areas it is usual and often compulsory to fit cyclone arrestors, bag-filter systems, or electrostatic dust precipitators between the kiln exit and the chimney stack. Modern cement plants are equipped with elaborate instrumentation for control of the burning process.
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).
Jul 09, 2017· Re: Low Pressure Drop Cyclones. Draft is negative pressure. There is a change in pressure across a cyclone and that change in pressure is referred to as the pressure drop, i.e. there is a more negative pressure at the outlet than the inlet. In a cement kiln negative pressure must be maintained on the rotary section of the kiln.
