CONTROL METHOD OF EXTERNAL HEAT TYPE ROTARY KILN

摘要

PROBLEM TO BE SOLVED: To solve the problem that the control of the temperature and atmosphere of an external heat type rotary kiln is not easy. SOLUTION: A temperature-measuring means 14 for measuring the temperature of a heating chamber 2, and an air-introducing means 4 for introducing air into the heating chamber are provided, and at the same time the air- introducing means is controlled according to temperature deviation for operation at a desired temperature and in a desired atmosphere.
