Cement Rotary Kiln

1.    Application and Operating Principle話信

The rotary kiln is the central equ光車ipment for cement clinkering system 去農in the new large dry p商店rocessing cement pro年家duction, which can be used with uni中外-stream or twin-strea山這m pre-heater, calcining c微討ombustor. 90%~ 95% of the raw mate知去rial which has been pre-calcined空麗 has been fed into the s話村low rotating and inclining instal藍答led rotary kiln from the rear愛畫. Under the composite ef拍金fect of circumferential tilting a鐘術nd axial movement, the material 唱技slowly flows through the whole drum,算城 the fuel (coal dust南制, oil or natural gas) spray呢頻s from kiln head into high temperatur子花e zone for burning, which prod西費uces the required heat for physical a地計nd chemical reaction of combination an上電d crystallization of material insid司中e the kiln. Under the function 東唱of rear blower, the burning 藍物gas steam and material counter flow the雜又 whole kiln, completing heat excha光討nge and physical or/and chemical校現 reaction. The clinkered cement is di外影scharged to the cooler.
