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.
Step 4 : Kiln. Raw meal now enters the huge rotating furnace called a kiln. It's the heart of the cement making process—a horizontally sloped steel cylinder, lined with firebrick, turning approximately four revolutions per minute. The kiln is the world's largest piece of moving industrial equipment.
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.

The application of rotary kiln originated from the cement manufacturing plant.. In 1824, J. Asper, a British cement worker, invented the intermittent shaft kiln. In 1883, Dietsch in Germany invented the continuously operated multi-layer vertical kiln.
Description of the technology process in shaft kiln The calcination of dolomite stone, which is one of the main stages of the sintered dolomite manufacturing, is chemical process which proceeds in a vertical shaft or rotary kiln. When heated, the dolomite decomposes according to the following endothermic reaction: CaMg(CO 3) 2 CaO + MgO + 2CO
