46 rows Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900 C, which is the point where the carbon dioxide is driven off, leaving calcium oxide, also known as quicklime.
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 quicklimeburnt lime. Vertical lime kiln is suitable for projects with smaller quicklime capacity for its low cost implementation. The capacity range of Daswell vertical kiln lime is between 100 to 500 tons per day.
The Vertical Kilns retain the generated heat and the efficiency is substantially better. Large 1,000 tonday capacity Vertical Lime Kilns are possible, are very energy efficient and easy to operate. Minimal maintenance is required, because the limestone is brought to the top and into the kiln.
Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, the vertical lime kiln is also widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.

As per the kiln operating temperature, heat transfer inner vertical shaft lime kiln can be divided into three parts A.Preheating zone. Limestone is heated from ambient to above 800 C by direct contact with the gases leaving the calcining zone i.e. products of combustion, excess air and CO2 from calcination.
The limestone calcining system is mainly made up of 10.5 8.5m vertical preheater, 4.0 60m rotary kiln and vertical coolder whose output is 600td and heat consumption of 5.75GJt. Limestone inside the preheater is heated by high-temperature gases from rotary kiln to 600-800 C, at which temperature limestone can be partly decomposed.
Lime rotary kiln has a vertical cooler. The filled cooler with dividable ventilation cools down the lime into 80 making it easier to be transported and stored. And it can preheat the secondary kiln air up to more than 700, which reduces the need for moving parts and special materials.

The shaft refers to a vertical vessel where the calcining takes place. Because of the weight of the bed of material in the shaft, there are limits on the size and strength of the type of limestone that can be calcined. Vertical kilns work on a batch-type system rather than continuous feed, and the upper kiln area is used for preheating.
