Kiln feed rate fluctuations and composition inconsistency makes difficult to control free lime in clinker. Clinker litre weight (grams/litre): A convenient supplement for free lime measurement is the more rapid determination of litre weight of clinker sample from the cooler discharge to approximately +6/-12 mm and weighing a standard 1 litre ...

IV. WEIGH FEEDER AND ITS CONTROL METHODOLOGY A weigh feeder in a cement industry is used to continuously feed bulk solids for grinding; these solids are clinker, gypsum and fly ash in 72.5, 2.5 and 25 percentage respectively. So weigh feeder is actually a conveyor belt through which material passes and is dropped to the mill for grinding.
