Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly …

The use of supplemental fuels such as waste solvents. Further kiln rotation causes the hot chains to fall into the cooler materials at the bottom of the kiln. and iron. Five different processes are used in the portland cement industry to accomplish the pyroprocessing step: the wet process. 1.
Production Process The manufacturing of cement is a complex, high-tech, high temperature process. The chemistry of our raw materials, the fuels and the temperatures inside our kilns are all carefully controlled.
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.

Basic Kiln Process In a cement kiln, there are two types of inputs, fuels and ingredients. Fuelsprovide the energy necessary to produce the heat required to raise the temperature of the ingredientsto the level required for clinker formation. Ingredients provide the materials that make up the actual clinker mass.
Quite a few wet process kilns are still in operation, usually now with higher-tech bits bolted on. However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower.

The cement industry is very capital intensive and depends largely on construction activity for a steady source of product demand. Energy costs can account for to 40 percent of the total cost of cement manufacturing. Conversion to coal was started in the 1970's. In 1972, only 39 percent of the industry's energy was supplied by coal.
recently, suppliers of alternative fuel to cement kilns, including cement company wholly- owned subsidiaries and private companies, have adopted terms such as “engineered fuel” when referring to fuels derived from many different industrial byproduct streams.

Cement manufacturing is an energy-intensive process due to the high temperatures required in the kilns for clinkerization. In 2005, the global cement industry consumed about 9 exajoules (EJ) of fuels and electricity for cement production (IEA 2007). Worldwide, coal is the predominant fuel burned in cement kilns.
heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of …

The use of alternative fuels in cement manufacture is also ecologically beneficial, for two reasons: the conservation of non-renewable resources, and the reduction of waste disposal requirements. The use of alternative fuels in European cement kilns saves fossil fuels equivalent to 2.5 million tonnes of coal per year (Cembureau, 1999).
Sustainable Manufacturing. As cement producers continue to search for alternative fuels, many people wonder what types of fuel can be used in the combustion process. The average energy input required to make one ton of cement is 4.4 million Btu—the equivalent of about 389 pounds of coal.
