Volume 3, Issue 5, November 2013 385 Abstract— formalized by French and British engineers in the 18th This paper analyzes an existing processing management system in a cement factory in India. During the last two decades (80's and 90's), major technological advancements took place in design of cement plant equipment/systems. The
The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.
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.

This is where the cement manufacturing process begins. Limestone is the major raw material used for producing cement, and is excavated from the captive mines held by the organization. The quarrying activity is carried out employing opencast mining technique, following drilling and blasting.
Cement manufacturing is truly a one-of-a-kind business. It requires a spectrum of technology found in few industries. The 24/7 continuous process of chemical and physical transformations in kiln systems that can reach one quarter of the sun's surface temperature is mesmerizing to all.
The principal raw material required for cement manufacturing is Limestone. Limestone is mined from the mines by blasting explosives and is transported from the mining area to the process plant and then fed into a primary hopper from where the limestone bolder is fed to the primary crusher (Jaw Crusher) with the help of a reciprocating feeder.
Cement Manufacturing Process 1 Extraction. Materials are extracted / quarried / recovered and transported to the cement plant. 2 Crushing and milling. The raw materials, limestone, shale, silica and iron oxice are crushed and milled into fine powders. 3 Mixing and preheating.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).

conveyor Next Raw mix kiln cooling Back preheating clinker storage at the plant Raw mill THE CEMENT MANUFACTURING PROCESS 1.GRINDING : The clinker and the gypsum are very finely ground giving a "pure cement". Other secondary additives and cementitious materials can also be added to make a blended cement. 1.
Cement Manufacturing Process Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
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.
