Lime Kiln Dust (LKD) The thermal decomposition process that creates quicklime drives off this by-product. Dust collection systems inside high-temperature rotary kilns gather Lime Kiln Dust (LKD). LKD contains not only calcium oxide and magnesium oxide, but also pozzolans such as aluminates and silicates. Quicklime does not contain these pozzolans.

Abstract Lime kiln dust (LKD) is a fine particulate material by-product produced during the lime burning processes. Current reuse options are chiefly focused on reuse in the cement industry which are limited by the inherent porosity of this by-product. Due to the presence of calcium (Ca), magnesium (Mg) and other elements which can serve as micronutrients to the …

A lime kiln is around 70-100 meters long and around 2-4 meters in diameter. The kiln is typically equipped with product coolers at the discharge end where hot reburned lime meets incoming secondary air in a counter-current heat-exchange process. Dusting in a lime kiln occurs when fine material chaotically swirls at the discharge end of the kiln.
