The rotary kiln cement plant can be divided into dry method cement plant and wet method cement plant. Their main difference lies in the cement rotary kiln. Raw meal calcined in the wet method kiln is a slurry containing 32% to 40% moisture, so the kiln body is longer and the clinker produced is of high quality with small dust pollution.

Several different types of kilns are used for the calcination process. These kilns can be rotary kilns or shaft kilns. The type of the kiln to be selected strongly depend on the characteristics of the raw dolomite, anticipated production rate, cost of fuel, investment costs, available fuel, local conditions, infrastructure and other things.

The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks. The kiln is supported on the columns of masonry or concrete and rested on roller bearing in slightly inclined position at the gradient of 1 in 25 to 1 in 30.

The shaft kiln in a modernized form is still used in some countries, but the dominant means of burning is the rotary kiln. These kilns—up to 200 metres (660 feet) long and six metres in diameter in wet process plants but shorter for the dry process—consist of a steel, cylindrical shell lined with refractory materials.

The main data defin-ing the kiln capacity are: the raw material (dolomite) consumption is 6.7 tones per hour and the sinter dolomite production is 3 tones per hour. The kiln operates in average about 7300 h per year. Heavy oil consumption is about 375-400 L per hours or 125-133 L per ton of sin-tered dolomite.

2. Carbon dioxide equivalent (CO2e) savings at Plant E were greater due to the substitution of biomass fuels for fossil fuel. 3. Results are from recent installations (since 2009).
