Vertical Lime Kiln Description

Vertical Shaft Kiln for Lime/Quicklime/Limestone
This vertical shaft lime kiln design adopt the fully automatic mechanization vertical kiln to produce active lime, suitable for the lime production project with single kiln within the scale between 100-300t/d, and it can also combine multi kilns. The lime can be widely used in building, chemical, metallurgy and other industries. Combined with the traditional vertical kiln, this fully automatic mechanization vertical kiln enjoy the advantages of energy-saving significantly, environment-friendly, higher automatic level, finished product with higher quality, short construction period, and appeal to many customers.

Vertical Lime Kiln Process Description

Production process:

The raw material for producing active lime is carbonate rock with the CaCO3 as the main chemical content, usually called limestone rock, that is limestone. Generally speaking, it should choose qualified limestone. If the raw material with big quantity mud, it should wash the raw material first, remove the mud and other impurities.

Limestone and coal are respectively fed into the storage bins by forklift. The lower parts of the bins have automatic weighing hoppers. After weighing according to the amount set by the computer, the limestone and coal are mixed. The mixed material is lifted by the skip car through the inclined bridge to the top of the lime kiln, and then is evenly sprinkled into the kiln through the loading equipment and the feeding equipment.

The raw material descends under the action of its own gravity in the kiln. At the bottom of the kiln, a roots blower cools the lime at the bottom of the kiln. The wind from the bottom exchanges heat with the lime and enters the calcining zone as fuel after its temperature reaches 600 degrees.

The Limestone from the kiln top passes the preheating zone, the calcining zone, and the cooling zone, and complete chemical reaction under the action of high temperature to decompose into calcium oxide (lime). After that, it is discharged from the kiln bottom by the disc ashing machine and the ash discharging device with the function of sealed discharge, to realize the non-stop wind unloading.
