Explore the cement manufacturing process below. Cement Vs. Concrete . Cement is often confused with concrete. A common misconception is cement and concrete are interchangeable terms. In reality, cement is the glue that binds concrete together, like flour (cement) in a loaf of bread (concrete).
Alternative Fuels in Cement Manufacturing 265 Cement production is an energy-intensive proc ess consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced, which accounts for 30 40 percent of production costs (Giddings et al., 2000; EC, 2001). Worldwide, coal is the predominant fuel burned in cement kilns.

Five fire hazards associated with the cement manufacturing process are outlined in the following sections. 1) Coal Storage. On average 0.2 – 0.3 tonnes of coal are consumed in the kiln per kilogram of clinker cement production. As such coal storage during cement manufacturing is an important component to consider in hazard analysis.
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.
Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly. The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference. NOTE:
