TECHNICAL FIELD

[0001] The utility model relates to mineral roasting technical field, concretely relates to a metallic mineral roasting device. BACKGROUND

[0002] With the rapid development of China's steel industry, the iron ore with high grade and easy to choose has been on the brink of exhaustion, and with the sustained and rapid economic development, the demand for lead, zinc, copper, nickel and other metals is also gradually rising, leading to the gradual exhaustion of the above-mentioned metal mineral resources. There are many high-iron and high-impurity refractory iron oxide minerals, and high-sulfur and lead-zinc and other metal impurity content high refractory iron ore and industrial solid waste resources in China, such as smelting copper slag, nickel slag and other iron-containing industrial solid waste.

[0003] The existing metal mineral is generally processed by continuous roasting to reduce the content of metal mineral impurities, thereby improving the quality of the mineral, but the existing equipment cannot effectively control the oxygen content of the air in the furnace during the roasting process, thereby affecting the quality of the metal product after roasting.

The catalyst is introduced through the feeding pipe and input into the spray base through the connecting pipe in the first top base. The minerals conveyed in the feeding screw are sprayed out from the spray nozzle to react, separating impurities and metallic minerals. Then, the minerals continue to be conveyed through the second connecting cavity into the oxygenation chamber.
