the rotary kiln can make the high quality lime with higher activity for steel making industry. under the same conditions, the activity of lime produced by rotary kiln is higher than that of gas-fired vertical kiln, with an average 30ml higher, and the activity is normally 340~380ml, even up to 400ml. 3.
rotary lime kiln is also called lime rotary kiln or limestone rotary kiln. it is used for the calcination of limestone to make quicklime. and specifically speaking, it is a slightly horizontal device that can rotate continuously to burn down the limestone thoroughly to make quicklime.
the kiln dries, heats, and calcines the counter-flowing lime solids. rotary lime kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by 400 ft (122 m) long. the refractory lining is from 6 in.

lime rotary kiln sets up a temperature-measurement interface, which is convenient to plug in temperature measuring devices to reach fully automated inspection. lime rotary kiln’s process of preparation is flexible.
a lime kiln is used for the calcination of limestone (calcium carbonate) to produce quicklime also called burnt lime. usually, the heat is around 900 degree celsius, but a temperature around 1000 degree celsius is used to make the calcination process more quickly. excessive temperature is discouraged because it produces “dead-burned” lime which is unreactive.

the conventional rotary lime kiln has a length-to-diameter ( l / d) ratio in the 30–40 range with lengths of 75–500 ft (22.7–152.5 m) and diameter of 4–11 ft (1.2–3.3 m). lime kilns are usually inclined at about 3 –5 slope with material charged at the elevated end and discharging at the lower end.
refractory bricks used in rotary lime kilns must meet these challenges as well as help conserve energy. minimizing heat losses through the kiln shell can help lime producers achieve production efficiencies that are essential in today’s competitive markets. heat loss through the kiln shell is of growing concern to lime kiln operators.
