During the First Five-Year Plan (1951-1956) cement production in India rose from 2.69 million tons to 4.60 million tons. By 1969 the total production of cement in India was 13.2 million tons and India was then occupying the 9th place in the world. 2)
The cement manufacturing process involves 6 key phases: 1) Raw material extraction through quarrying, 2) Grinding, proportioning, and blending of raw materials, 3) Pre-heating of materials using hot gases from the kiln, 4) Firing materials in a rotating kiln at 1450°C to form clinker, 5) Cooling of clinker using forced air, 6) Final grinding of clinker along with …
The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 - Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3).
The cement production is one of the most energy consuming processes, typically accounting for 50 to 60% of the production costs. However, there are several ways of heat recovery opportunities to achieve better energetic …
