WASTE HEAT RECOVERY POWER PLANTS IN CEMENT INDUSTRY S K Gupta / S K Kaul Holtec Consulting Private Ltd., Gurgaon, India ABSTRACT In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases.
• Delmas Plant: – Construction of a 1.3 million tons a year cement grinding plant in Delmas, in Mpumalanga province. • Kendal Ash Plant: – Sephaku Cement (through its Sephaku Ash subsidiary) has constructed a R71 million state of the art Ash Plant – In August 2009 – the 1,2 million tons per year Ash classification plant was commissioned
The pellets are baked hard in a pre-heating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.

Aug 07, 2013· •Indian Cement Industry comprises of 140 large and more than 365 mini cement plants. •According to ACC cement report, Government's continued thrust on infrastructure will help the cement to maintain an annual growth of 9-10% in 2010.
Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy-intensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 -- a decline of 89 percent -- while the number of ...
As overall demand for cement has shifted from the developed to the developing world, most new capacity investment is located in Africa, Latin America, and Southeast Asia, with China shifting to a more mature stage. The cement industry has not, however, taken full advantage of reallocation.
