Abstract
Abstract
Molybdenum concentrate oxidation roasting is an important part of molybdenum metallurgy process. Aiming at the current situation of high energy consumption in the process of oxidation roasting and drying of molybdenum concentrate powder in China, based on the analysis of traditional mechanism and process of molybdenum concentrate roasting and heat transfer in rotary kiln, the heat is adjusted and a new rotary kiln drying system is designed to make 16-20% high-moisture molybdenum concentrate powder once dried. Drying each ton of molybdenum concentrate powder can save about 308125kJ of heat, equals toabout 14.38M gas or 10.53kg standard coal.
