Introduction. according to the calcination character of limestone, lime rotary kiln is specialized design for production of active lime. this type of kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple.

It starts the calcination process by using hot process gases from the rotary kiln to preheat the feed material prior to it entering the kiln. its design allows for the hot gases to be drawn around the full circumference at the cassette level, entering the cassette equally on all sides before being drawn up through the descending stone.

Rotary kilnsrotating industrial drying ovensare used for a wide variety of applications including processing raw minerals and feedstocks as well as heattreating hazardous wastes. they are particularly critical in the manufacture of portland cement. their design and operation is critical to their efficient usage, which if done incorrectly.

Kraft pulp mills uses a rotary lime kiln to convert the calcium carbonate mud from the clarifiers to quick lime or calcium oxide. a typical kiln installation is shown in figure 1. it consists of a mud filter where the moisture content is reduced to about 30 to 35, a rotary kiln and dust collector. the kiln itself.

Lime and dolomite rotary kilns are the most widely used rotary kilns after cement kilns. the rotary kiln was invented in 1885 by the english ransam, which consisted of a horizontal tube with a gentle slope that could rotate around its axis and move the material gradually from one end to the bottom.

Lime bricks. the pfr kiln. for softburnt lime, the high reactive quicklime. the pfr kiln from maerz is ideal for the production of softburnt lime. the lime is calcined in a parallel flow. the feedstock and the combustion gases move in the same direction from top to bottom. the energy needed for the calcination is supplied at the begin.
