Clinker is mixed with gypsum and ground to a fine powder to makecement.Coalis used as an energy source incement production. Large amounts of energy are required toproduce cement. It takes about 200 kg ofcoalto produce one tonne ofcementand about 300-400 kg ofcementis needed to produce one cubic metre of concrete.

Mar 01, 2016·Coalprovides around 90% of the energy consumed bycementplants around the world, despite the environmental harm caused by its combustion. It takes 200 - 450kg ofcoaltoproduce1t ofcement. Thecementindustry consumes around 4% of globalcoal production, around 330Mt/yr.
The secondary source (40% of total emissions) is the burning ofcoal/fuel to provide the heat required for thecalcinationand clinkeringprocess. In terms of weight, roughly 900 g of CO2 is produced as a by-product, for every 1 kg ofcement produced.
Energy Source forCement Kilns: KIS: KISPL meetscoalquality specification forCement Production: JANUARY 10, 2008, NEW DELHI The two basicprocessesincement productionare the wet and dryprocesseswhich are named after the manner in which the raw mix is introduced into the kiln. In the wetprocessthe mix is introduced into the kiln as a slurry with 20-40% moisture.

Aug 30, 2012· Kiln is heating up from the exit side by the use of natural gas andcoal. When material reaches the lower part of the kiln, it forms the shape of clinker.CementManufacturingProcessPhase V:Coolingand Final Grinding. After passing out from the kiln, clinkers are cooled by mean of forced air.

The heated air from thecoolersis returned to the kilns, aprocessthat saves fuel and increases burning efficiency. After the clinker is cooled,cementplants grind it and mix it with small amounts of gypsum and limestone.Cementis so fine that 1 pound ofcementcontains 150 billion grains.
Encapsulated uses of CCR involve binding the coal ash, such as in wallboard, concrete, roofing materials, and bricks in a way that minimizes the CCR from escaping into the surrounding environment. There are important benefits to the environment and the economy from the use of coal ash in encapsulated form.
