The prevalent type of kiln is the rotary kiln, accounting for about 90 percent of all lime production in the United States. This kiln is a long, cylindrical, slightly inclined, refractory-lined furnace, through which the limestone and hot combustion gases pass countercurrently. Coal, oil, and natural gas may all be fired in rotary kilns.Rotary Kiln. Rotary Kiln typically 55 meters long with a four-meter diameter, the Waelz Kiln is slightly inclined 2-3% and has an approximate rotary speed of 1.0 rpm. As the moist material moves through the rotary kiln, it is dried and preheated by the kiln gas, flowing in a counter-current pattern.

Cement rotary kiln: cement rotary kiln is a laterally set cement kiln that inclined to a certain angle with the ground. Raw meals in the kiln body will be calcinated in a low-speed rotation. In present cement plants, the new dry process cement rotary kiln is the most widely used.Burning of raw materials is usually done in rotary kiln which is made up of steel tube, lined inside with refractory bricks and rotating at speed of 0.5 to 2 rotations per minute. The kiln is slightly inclined so that the material fed in at the upper end travels slowly to the lower and firing and discharging end.

The hydrolyzed titanium dioxide filter cake after dehydration and calcination at high temperature above 1000 C cake uses the inclined titanium dioxide rotary kiln body to both roll in the circumferential direction and move in the axial direction (from high end to low end) to continuously complete the dehydration and calcination process.in an inclined horizontal rotary kiln, which rotates at a programmed speed. A temperature profile ranging from 7000C-10500C should be maintained along the length of the kiln at different zones. As the material flows down due to rotary action and gravity, the ore is reduced. The kiln is divided into two zones; the pre-heating zone and
