Rotary kilnsare a critical component in manufacturing of cement,limeand mineral products. With over 35 years of experience servicing these industries, A-C Equipment plays a critical part in the ongoing design, fabrication and repair of theserotary kilninstallations.
Refractory, or the lining utilized on the interior ofrotary kilns, is a critical component in ensuring process efficiency and prolonging the life of arotary kiln.Here, we’ll discuss everything you need to know about refractory, including how it works, the different types, and best practices for preventative care.
A. A Boateng, inRotary Kilns(Second Edition), 2016. 1.1 TheRotary KilnEvolution.Rotary kilnshave been synonymous with cement andlime kilnsprobably because of the history of their evolution and development. It has been reported that cement deposits characterized by Israeli geologists in the 1960s and the 1970s place cement making at 12,000,000 BC when reactions between limestone and oil ...
Refractory bricks used inrotary lime kilnsmust meet these challenges as well as help conserve energy. Minimizing heat losses through thekilnshell can helplimeproducers achieve production efficiencies that are essential in today’s competitive markets. Heat loss through thekilnshell is of growing concern tolime kilnoperators.
Thelime rotary kilnis with advanced structure. Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of thelime-stones can reach 20~25% when they enter thekiln. Besides, thelime-stones, with fine fraction about 10~15mm, can be used directly. 2.Waste Heat be Reused Effectively
Refractory is a critical component in the design of a direct-firedrotary kiln, helping to protect thekilnshell from the harsh processing environment within. A customizable part ofkilndesign, refractory can be engineered to suit the unique needs of an application, with factors such as material and multiple layers coming intoplay.

Rotary KilnAlignment. The continuity of operation of alimesludgekilnrequires strict maintenance control. Therotary kilnis among the largest type of moving machines made and is subjected to extreme temperatures, power failures, atmospheric conditions, varying loads, and other operating conditions which affect its wear and alignment.
Lime calcining systems. Metso has supplied more than 210lime calcining systems, over 115 of them as preheater/rotary kilnsystems. The worldwide total annual production capacity from Metso-supplied systems exceeds 30 million metric tons per year.

Alime kilnis akilnused to produce quicklime by the calcination of limestone (calcium carbonate).The chemical equation for this reaction is:. CaCO 3 + heat → CaO + CO 2. Limestone is poured into one side of thekiln, it is then heated up with hot air and quicklime [Calcium Oxide] comes out the other end.

Alime kilnuses heat, motion, and airflow to convertlimemud tolime, or in chemical terms, calcium carbonate to calcium oxide. This process is referred to as "calcining". The most commonlime kilndesigned found at kraft pulp mills is therotary lime kiln. Arotary lime kilnis basically a long tube or cylinder set at a slight incline that ...
