METHOD FOR BURNING EXPANDED CLAY IN ROTARY KILN AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC C04B20/04 F27B7/00 

FIELD: construction.

SUBSTANCE: method for burning the expanded clay in the rotary kiln comprises assignment of the required values of the expanded clay temperature at point corresponding to the end of the heating zone, and temperature at point corresponding to the middle zone of swelling, determination of temperature at point corresponding to the end of the heating zone, and temperature at point corresponding to the middle zone of swelling, determination of difference between the required and actual value of temperature of expanded clay at point corresponding to the end of the heating zone, formation in function of difference magnitude of these temperatures of control influence on drive of belt feeder, definition of difference between the required and actual value of the expanded clay temperature at point corresponding to the middle zone of swelling, formation in function of difference magnitude of these temperatures of control influence on the furnace burner, the required value of the expanded clay temperature at point corresponding to the end of the drying zone is specified additionally, temperature at point corresponding to the end of the drying zone is determined, difference between the required and actual value of the expanded clay temperature at point corresponding to the end of the drying zone is determined, control influence on drive of the furnace rotation is formed in function of difference magnitude of these temperatures. Invention also relates to the device for the expanded clay burning.

EFFECT: improving the quality of expanded clay, including its strength, reducing the number of process wastes during the production of expanded clay, stabilization of burning process.
