CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. Dear Sirs, what is the difference between a clinker produced in a rotary kiln and the clinker produced in a vertical shaft kiln? I know that the disadvantages of the VSK kiln are the inclusion of ash in the clinker, the problem with homogeneity of heat distribution, the low production.
Shaft kiln, also known as vertical kiln, vertical shaft kiln, is a vertical and fixed clinker firing equipment.The raw meal ball with coal is fed into cement kiln from the kiln crown, and raw meal ball moves from top to bottom, air move from bottom to top. In fact, the physical and chemical changes of shaft kiln are similar to that of cement ...

Kilns to produce cement are almost equally old. Now cement kilns can be divided mainly into 2 types: vertical shaft kiln and rotary kiln. The vertical kiln is the older type and its origin dates back to the 5 th century AC. Rotary kilns were first used in 1880. Around the 20 th century, they replaced vertical shaft kilns almost everywhere.
The energy intensities found in the studied vertical kilns are higher than those reported for the best available technology for lime calcination, the twin shaft regenerative kiln. The calcination process efficiency in the studied companies is on the order of 55–60%, while the twin shaft regenerative kiln achieves an efficiency of 80–90%.

Rotary kilns have been used successfully for many years to produce calcined coke for the aluminium industry and they offer a high level of automation, performance and flexibility. Shaft calciners make a high bulk density, coarse particle size product and several papers have been published recently highlighting these benefits.
A PFR kiln (parallel flow regenerative shaft kiln) consists of two vertical shafts and a connecting crossover channel. Both shafts work with each other. While one calcines the product, the other preheats the stone. In the burning shaft the lime is calcined in parallel flow. The hot combustion gases are then transferred through the crossover ...
The Twin Shaft Regenerative (TSR) kiln family consists of two main groups: Direct Crossover featuring a single channel placed between the shafts, Radial Crossover featuring circular channels around the shafts which are then connected in the central part. The TSR-Kilns series utilizes the regenerative process for lime calcination.
