As preheater towers are of different designs and the build-up appears in various locations depending on design, raw material and other factors, a flexible solution is required.
The five-stage cyclone preheater we produce and supply is the most commonly used cyclone preheater in cement plants nowadays. The five-stage cyclone preheater is composed of six cyclones in total. One of the two cyclones at the top stage is thin and high, the purpose of this design is to improve the gas-solid separation efficiency.

Preheater Tower that I have to design is a concrete structure that support different equipment of cement industry. (as also shown in pic that you uploaded in your previous comment.But your pics shows that it is steel structure truss and I have to design concrete structure with same equipment)
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.
Kilns used in cement manufacturing are complex in nature. They have longer time constants, and raw materials used have variable properties. ... In general, a PH tower consists of 1 to 6 cyclone stages, which are disposed one above the other in a tower. The PH kiln performance can be extended using precalcination technology. ... This latter ...

Preheater. Preheater and precalciner kilns are shorter than a long cement kiln and contain tall preheater towers that use the heat produced by the kiln to caloine the raw materials as they move through the various stages of the tower. These kilns reflect the latest in cement kiln design technology. They are more fuel efficient than long kilns ...
The heat exchange between the gas and the material takes place in the cyclones while both are in suspension. Many different designs of preheater towers are in existence using this basic principle. The most common design is the parallel four-stage preheater. Some of these can reach output rates of up to 8000 metric tons per day.
The preheater tower actually does a rather good job of removing SO2; if all the sulfur in the kiln feed is assumed to be present as sulfides, the tower efficiency may be as high as 78%. The injection of water into the riser duct from Stage II has achieved about a 10-20% reduction of emissions, but at a substantial energy penalty.
