Abstract
The lime calcining rotary furnace has one cylindrical furnace body, one calcining sieve barrel set concentrically inside the cylindrical furnace body, and several partition boards set homogeneously between the calcining sieve barrel and the cylindrical furnace body. During the rotation of the furnace body, crushed limestone is distributed in the channels the calcining sieve barrel and the partition boards form, heated homogeneously with the flame of the coal powder burning sprayer, and made to shift toward the relatively lower discharge port. The present invention has raised heat energy utilization and continuous operation and is superior to fixed kiln.
