Clinker rotary kiln is a professional equipment designed according to the characteristics of clinker. The calcination process of clinker includes crushing and pre-homogenization, raw material preparation, homogenization of raw meal, preheating decomposition and clinker burning.
These suggest that theclinkernodules larger than 0.6 mm φ were formed exclusively by nodulization. The concentration of K 2 O and SO 3, as well as the fine textures of alite, can thus provide a good indicator of the firing and nodulization process in therotary kiln.

The Air-Quenching shaking grateClinkerCooler was developed more than 20 years ago as an improved heat recuperating cooler for use withrotary kilns. It was designed to air quench and cool large quantities of hotclinkerrapidly, and to recover and return to thekilna major portion of the heat from theclinker.

RotaryCooler:rotarycooler is the earliest used one in the cement plant.It is similar to the cementrotary kilnin appearance and equipped with refractory lining and material lifting device inside. The high-temperatureclinkerenters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange.
In its simplest form, therotary kilnis a tube up to 200 meters long and perhaps 6 meters in diameter, with a long flame at one end. The raw feed enters thekilnat the cool end and gradually passes down to the hot end, then falls out of thekilnand cools down. ... After cooling, theclinkermay be stored temporarily in aclinkerstore, or it ...
Rotary Kilnis a kind of roasting device, or calcining equipment, is used to convert one material into another type, as the working temperature is high, usually ranges from 600-1450 ℃, so it needs to use refractory brick inside. According to different application, therotary kilncan be divided into: CementRotary Kiln, quicklimerotary kiln, Oil Proppantrotary kiln, and chemicalrotary...
