Use of Sewage Sludge in Cement Industry

Till now e g in germany around 53% of all sewage sludge ( around 1 2 mio tons dry substance) is used as fuel- in coal fired power plants or in cement Plants This saves around 500 000 tons of coal ( coal CV 6200 kcal dreied sewage sludge 3500 kcal) Get price

Carbon Capture in the Cement Industry Technologies

Unlike most industrial processes process chemistry rather than fuel combustion is responsible for almost two-thirds (64%) of the CO 2 emissions emanating from the Portland cement industry As shown in Figure 1 around 880 kg CO 2 is generated per tonne of clinker in a typical (1 Mtpa 3 000 tpd) cement plant which produces CEM I (95% clinker) Get price

What is Cement Clinker? Composition Types Uses

Clinker when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely produces cement Clinker can be stored for long periods of time in a dry condition without degradation of quality hence it is traded internationally and used by c ement manufacturers when raw materials are found to be scarce or unavailable Get price

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product Clinker occurs as lumps or nodules usually 3 millimetres (0 12 in) to 25 millimetres (0 98 in) in diameter It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage Get price
