May 02, 2013#0183;#32;If the pieces which are decomposed fully and still reside in the calcining zone, sintering occurs. Cooling zone Lime which leaves the calcining zone at temperatures of 900 deg C, is cooled by direct contact with cooling air, part or all of the combustion air, which in turn is preheated. Lime leaves this zone at temperatures of less than 100 deg C.
Applications: Cement, silicate products, new building materials, refractory materials, glass ceramics and other production industries. Applicable materials: limestone, cement clinker, bauxite, activated lime, aluminum hydroxide, bentonite, etc. Uses: The grate cooler is an important main equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker.
The preheater, using hot process gases from the rotary kiln, preheats and begins to calcine the limestone feed material. The material finishes calcining in the rotary kiln. The kiln discharges into a stationary cooler where the lime product is cooled to temperatures low enough to be handled by typical rubber belt conveying equipment.
lime calcining system Active lime calcining system consists of a vertical preheater rotary kiln cooler. Vertical preheater Vertical preheater is composed of a preheater body a storage bin a feeding pipe hydraulic push rod device etc..

The riding ring of a rotary kiln being resurfaced in the field Specialized services Coolers Metsos lime calcining technology includes the KVS/Niems high efficiency contact cooler. With heat recovery efficiencies in excess of 90%, this direct contact, counterflow heat exchanger provides both extensive cooling of the lime product, and significant preheating of secondary combustion air for the kiln firing
The kiln discharges into a stationary cooler where the lime product is cooled to temperatures low enough to be handled by typical rubber belt conveying equipment. Applications This plunger style, packed bed preheater is used exclusively in the global lime industry as a limestone feed metering, heat exchanger to improve the overall fuel efficiency of a rotary kiln pebble lime calcining system.
t/d active lime production line developed and designed by our company adopts Preheater kilncooler Process, has better flexibility of raw materials and fuel, with high activity of produced reactive lime, providing excellent raw materials for steel and alumina industry. Features of Our lime calcining System:
Pebble lime calcining is a process by which carbonates of calcium and magnesium (CaCO 3 and MgCO 3), or limestone, collectively, are heated to temperatures high enough to drive off CO 2 and produce oxides of calcium and magnesium (CaO and MgO), lime product. The process takes place within three major pieces of equipmentpreheater, rotary kiln and stationary cooler.

TK: For customers dealing specifically with fine ores, we designed the Gas Suspension Calciner (GSC) technology something we have supplied since the beginning of the 1970s. It consists of a series of preheating cyclones, a calciner vessel and a series of cooling cyclones. Hot air is introduced into the system via an external air heater.

The lime vertical cooler is often attached to the lower end of rotary lime kiln. Lime vertical cooler for rotary lime kiln has two main functions. One is to cool down burnt lime that has been treated in rotary lime kiln.
A typical pulverized fuel/gas burner Metsos rotary cooler design utilizes both a direct water quench of the hot coke at the cooler entrance and counterflow movement of ambient air to cool the coke. The direct quench type is the most widely used method of cooling in the coke calcining industry.
In sugar refining, a suspension of hydrated lime in water is used to adjust the pH of the product stream and precipitate colloidal impurities. 7 The lime is then removed by reaction with carbon dioxide. 7 Product coolers are emission sources only when some of their exhaust gases are not recycled through the kiln for use as combustion air.
The cooler is one of the main equipment for quick lime calcining. It is widely used in building materials, chemical industry, metallurgy, etc and work as the matching facility of rotary kiln. CHAENG can not only supply the cooler,but also provides design,selection, installation and commissioning for the whole active lime production line,this will make custom more convenient.
