Molybdenum iron smelting rotary kiln

The main function of oxidizing roasting of molybdenum concentrate is desulfurization, which is an exothermic reaction process. According to this principle, our company has developed a self-heating sulphide ore roasting rotary kiln for roasting molybdenum concentrate due to the heat supplied during roasting. The air is sufficient, so the oxidation process is accelerated, the equipment capacity is increased, and the product quality is good. The MoO3 in the calcining can reach more than 80%, which makes the smelting effect of ferromolybdenum better.

product description

Technical performance and characteristics

High output, energy saving and environmental protection

The roasting quality is good, the output of single set of equipment is large, the equipment has long service life, saves energy and is convenient for environmental treatment. The exhaust gas treatment system can recover materials.

No external heat source required, high degree of automation

The external drying heat source is eliminated in the system, which saves equipment investment and saves external heating source for drying, automatic batching system, accurate metering and mixing, good system tightness and high degree of automation.

Reduce the workload and solve the blackening problem

Reduce the labor intensity of workers, improve the operating environment, solve the problem of blackening of tail gas sulphuric acid products, and reduce the energy consumption of sodium sulfite produced by roasting tail gas.

High recovery rate, zero CO2 emissions

The production system has reached the automatic control operation, the heat energy consumption in the production process is close to zero, the CO2 emission is close to zero, and the product recovery rate can reach above 98.5%.

working principle

A heat exchanger is arranged in the rotary kiln to ignite the molybdenum concentrate to establish a calcination temperature zone, and the heat released during the roasting process is replaced with a portion of the heat by the air, and the recovered hot air is re-reasonable by the heat exchange device. It is input into the roasting rotary kiln to keep the molybdenum concentrate in the kiln kept roasting. Under this working condition, no external heating source is needed to achieve the self-heating roasting of molybdenum concentrate, and the external heating energy consumption approaches zero and the CO2 emission approaches zero.
