FIELD: mining.
SUBSTANCE: mine kiln comprises a lower mine and an upper circular mine entering into its cavity forming a gas channel. The said mines are interconnected with a metal structure with air-cooled metal ring at the base of the upper mine. The walls of the upper mine located above the metal ring in the area of the gas channel are made of refractory bricks. The metal ring is rigidly connected to the air-cooled metal beams mounted transversely and resting on the housing of the lower mine.
EFFECT: simplified design of the mine kiln and reduced cost of its manufacturing.
