Vertical shaft kilns have among others the advantage of low investment profile and hence very suitable for small ... The basic PR system has two shafts, but three shaft systems are used with small size grains to address the increased flow resistance associated with smaller feed sizes.
In a shaft kiln, the limestone | dolomite moves counter flow to hot gases in the shaft. This gives shaft kilns the lowest fuel consumption of any type of calciner. The shaft refers to a vertical vessel where the calcining takes place.

Vertical lime kiln is also called vertical kiln lime or vertical shaft kiln for lime. It is a vertical static device for the decomposition of limestone to produce quicklime/burnt lime. Vertical lime kiln is suitable for projects with smaller quicklime capacity for its low cost implementation.
Shaft kiln is also called vertical shaft kiln which is one of the cement kilns widely used in the cement production line. As the main cement equipment, it plays an important role in cement manufacturing.

Slide 3, below, shows a schematic of the exterior of a modern rotary lime-reburning kiln. Slide 4 shows a schematic of the interior features of a
Kilns operating with gaseous, liquid and pulverised solid fuels, or a combination of these, have been built worldwide. Finelime Kiln Typical stone sizes processed in conventional vertical shaft kilns are larger than 30 mm. Stone sizes of 6 to 30 mm can be calcined
Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.
Our standard linings for vertical shaft kilns consist of wear-resistant hot-face linings and thermally efficient backup linings. This combination provides lime producers with an economical and tough refractory lining that can withstand the thermal and mechanical challenges present in a vertical shaft kiln.
The vertical kiln was manufactured by ZK group with modern new technology, which is an environment protection, save energy, higher machanization and automaticity, quite modern lime kiln. The selection of the active lime process is effected by many factors, such as : the activity requirement, the fuel, the limestone sizes, production capacity, environmental-protection requirement.
Vertical shaft kiln. Rotary Kilns A rotary kiln, as shown diagramatically in Figure 2 , is a long refractory-lined inclined tube slowly rotated to ensure the steady flow of solid material from the feeder at the higher end to the collector at the lower.
