Flash Calciners 

Kerone’s Flash Calciners are high-efficiency, continuous thermal processing systems in which very fine powders or slurries are rapidly calcined in a matter of seconds by direct suspension in a high-velocity stream of hot combustion gases. Unlike conventional kilns where the material must spend minutes or hours at temperature in a bed or charge column, Flash Calciners achieve the required calcination reaction almost instantaneously by maximizing the exposed surface area of each particle and the heat and mass transfer driving forces between the hot gas stream and the suspended fine particles. Kerone engineers Flash Calciners for the calcination of aluminium trihydrate (Bayer alumina), clay minerals, calcium carbonate, and various fine mineral and chemical feed materials where extremely fine feed particle sizes, high production rates, and compact process layouts are required. The technology achieves superior product quality with minimum specific energy consumption compared to traditional rotary kiln processing of fine powders.
