The energy-saving rotary kiln takes advantage of the characteristic of self-heating reaction during the roasting of sulfide ore. The heat released by roasting can fully meet the heat required for the next process without generating a large amount of flue gas. Based on experiments on the oxidation roasting mechanism of sulfide ores, we proposed an optimized design plan for an internally heated rotary kiln, adopting a number of patented technologies, adding kiln heat exchange and air supply devices, cylinder expansion devices, and adopting novel slip rings. Structural design of power supply device and so on. It has high output, high efficiency, zero energy consumption and other performance advantages that ordinary rotary kilns cannot match.

Features
Carbon-free roasting, energy saving and environmental protectionOxidative autothermal roasting of molybdenum concentrate, zinc sulfide ore, copper sulfide ore, pyrite, etc. has achieved good economic and environmental benefits during operation. The volume of rotary kiln exhaust gas has been reduced by about 50%, suppressing the SO2 dilution effect, making subsequent The acid-making process is easier to implement.
Optimize design and improve performance
The optimized design of the internally heated self-heating roasting rotary kiln adds a heat exchange and air supply device for the kiln body, a heat compensation device for the cylinder body, and a thermal insulation device for the cylinder body. When used for chemical molybdenum oxide roasting, it can save energy by >50%, has a good oxidizing atmosphere, and increases output by ≈15% compared with ordinary rotary kilns.
Fast oxidation reaction and good desulfurization effect
Because this technical process provides more sufficient oxygen for the roasting of molybdenum concentrate, the oxidation reaction of the molybdenum concentrate is faster and more complete, resulting in good desulfurization effect of the product. The sulfur content of the product is about 0.07%, which is far lower than the domestic sulfur content of 0.1%. standard.
Long service life and good working environment

Working principle
The purpose of oxidative roasting of molybdenum concentrate is to separate molybdenum and sulfur in molybdenum disulfide, so that MoS2 can be converted into MoO2 or MoO3 at high temperature. The roasting of molybdenum concentrate is a significant exothermic reaction and can be completely self-heating. The roasting process does not require the consumption of heat energy and should not produce a large amount of smoke. The principle of the energy-saving rotary kiln is to use the heat released by the roasting reaction of molybdenum concentrate to recover heat energy and maintain the autothermal reaction (without external heat source). The thermodynamic trend and thermal balance potential of molybdenum concentrate roasting are very obvious. The heat released by the oxidation of molybdenum concentrate is With full recycling, zero heat energy consumption roasting can be achieved.
