Cement Kilns: Design features of rotary kilns The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400°C, while the gas temperatures reach 1900°C.
Manufacturing of cement using Vertical Shaft Kiln (VSK) Process is widely used for small scale cement production, A Pre Processing In this phase, . Chat; Vsk Technology Kiln .
The most common process for the production of sintered dolomite is a single stage firing process in a shaft kiln or a rotary kiln. The raw dolomite is charged into the kiln and, while progressing through the kiln, it gets decomposed in two steps.
A vertical shaft kiln (Fig. 1) is basically a moving bed reactor a system [16,21]; and its implementation in the production process is with the upward ﬂow of hot combustion gases counter-current to a very efﬁcient way to enhance the energetic performance of a process the downward ﬂow of limestone particles that undergo calcination .
May 31, 1988 · A vertical shaft kiln utilized in calcining limestone defines a series of processing zones including an upper preheating zone, a first calcining zone, a second calcining zone having a length twice that of the first calcining zone and a material cooling zone, Burners inject burnt gases intermediate the two calcining zones.
Vertical shaft brick kiln technology is adopted by customers for projects of smaller capacity for its low cost implementation. It is modern day answer for cost effective production and a boon for the developing countries where lower production levels are the need of the country.

Regenerative kilns Edit. These typically consist of a pair of shafts, operated alternately. First, when shaft A is the "primary" and B the "secondary" shaft, the combustion air is added from the top of shaft A, while fuel somewhat below via burner lances.
kiln technology with the more complex dry process rotary kilns keep the mix of pyroprocessing technologies in China's cement industry more diverse than in almost any other country.
Working Principle of Vertical / Shaft Kiln: Large 1,000+ ton/day capacity Vertical Lime Kilns are possible, are very energy efficient and easy to operate. Minimal maintenance is required, because the limestone is brought to the top and into the kiln.
The shaft kiln looked something like a chimney where the limestone was put in at the top and fired from below. The continuous process would provide lime at the bottom as limestone was added to the top.
