Some rotary lime kilns operate under reducing conditions by curtailing the
combustion air to substoichiometric levels so as to volatilize any sulfur that may
be in the limestone in order to meet the stringent sulfur specifications imposed by
steel and chemical users. For most operations except for dead burnt dolomite, the
burner tip velocities can range between a low of 25 m/s and a high of about 60 m/
s. These are significantly lower than the velocities of cement kilns, which operate

There exist a need for considering appropriate refractory scheme most suited to
the different requirements of various zones in a rotary cement kiln. Study of
various joints, correct engineering practices for joining the bricks, the role of key
bricks including the method of fixing key bricks; the design of retaining rings and
their installation are some of the very important aspects of systems design and
engineering. Typical problems faced in installation of refractory should also be
addressed to ...

Precalcination may also make it economically feasible to deal with the problem,
discussed in Section 3.2.5, of formation of deposits in the duct carrying the hot
gases from the kiln to the preheater. 3.2.4 The rotary kiln The rotary kiln is a tube,
sloping at 3-4% from the horizontal and rotating at l-4rev/min, into which the
material enters at the upper end and then slides, rolls or flcrwITcounter to the hot
gases produced by a flame at the lower or 'front' end. In a system employing a
precalciner ...

Clinker produced under such conditions is greyish,green in colour. whereas if
reducing conditions are used the clinker is brownish and produces cement with
lower strength and faster setting properties (Kohlhaas. 1983. p. 119). The early
Ransome kilns were about 0.45 m diameter and 4.6 m long. The size of the dry
process kilns used today is typically 4 m diameter and 70 m long. Modern rotary
kilns can produce between 6000 to 8000 tonnes of cement clinker per day (

The background for using fuzzy control in the cement industry and other process
industries is described, and some of the general practical problems of installing
high level process control equipment are discussed. A design methodology is
described for development and implementation of high level control strategies,
and finally, some typical results are presented from industrial application of fuzzy
control in the cement industry. 1 Introduction Process control in general and
rotary kiln ...

The rotary cement kiln is the heart of the cement-manufacturing process. The raw
materials which are the basis of cement are blended together in a finally ground
feed which is continually introduced into the rotary kiln. The raw materials are so
proportioned that the correct balance of chemical constituents are present in the
feed. The raw materials then undergo a transformation within the kiln as a result
of being exposed to high temperatures in a dynamic environment. The result is ...
