Rotary kiln is indispensable core equipment in modern dry process cement plants.The design process of a rotary kiln covers the calculation and formulation of various parameters, which is a very complex process. Here we only briefly introduce the determination of some fundamental parameters in the design of rotary kiln.
The kiln is the centerpiece of the cement plant. Its role is to transform the prepared material into clinker by bringing it to a temperature ranging from 1000 to 1500 °C.
The kiln is the heart of the plant – what an entire cement plant is dimensioned around, and where most of the final chemical reactions take place. So it’s not surprising that a producer requires an ideal kiln solution. FLSmidth’s ROTAX-2® and 3-base kilns deliver the best in rotary kiln designs. With the ideal temperature profile and
