Aug 30, 2012·Cement Manufacturing ProcessPhase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart ofcementmakingprocess. Here, raw material is heated up to 1450 ⁰C. Thistemperaturebegins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

Cementis so fine that 1 pound ofcementcontains 150 billion grains. Thecementis now ready for transport to ready-mix concrete companies to be used in a variety ofconstruction projects. Although thedry processis the most modern and popular way tomanufacture cement, some kilns in the United States use awet process.

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

Stage ofCementManufacture. There are six main stages ofcement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The rawcementingredients needed forcementproduction 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.

Cement Manufacturing Process Cementis the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because onlycementhas the ability of enhancing viscosity of concrete which in returns provides the better locking of …

In thecement manufacturing processlarge fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce thetemperatureof the hot clinker leaving the kiln 1. All these airflows have to be adjusted and controlled as atmospheric conditions,processcon-

The use ofalternative fuels in cement manufacturing, therefore do not only afford considerable energy cost reduction, but they also have significant ecological benefits of conserving non-renewable resources, the reduction of waste disposal requirements and reduction of emissions.
