Jun 07, 2009· 1 Introduction. Online measuring methods are indispensable for process control in cement factories. However, while measurements of temperatures, pressures, filling levels, flow rates, motor powers and gas analysis parameters are long established, the online measurement of material parameters for process control purposes is far less common.

Cement industry is not a water polluting industry. Only the cooling tower blowdown associated with the GCT is a source of waste water generation, which does not have much significance as a water pollutant. The waste water is treated in septic tanks or sewage treatment plants and is used for gardening, irrigation and other purposes.
