AI Technical Summary
Existing microwave roasting systems occupy a large area and are difficult to effectively break up the inclusions in gold tailings, affecting subsequent grinding efficiency.
Design a microwave roasting furnace device that integrates multiple microwave roasting components and a conveying mechanism into a single furnace cavity. The conveying mechanism is distributed vertically, and the tailings material slides down by its own gravity. Combined with the temperature of the microwave roasting equipment and the material baffle thermometer, the design of the material baffle ensures uniform microwave irradiation and crushing of the encapsulated material.
It effectively saves equipment floor space, achieves uniform roasting of tailings materials, breaks up gold inclusions, improves grinding efficiency, and reduces the generation of harmful gases.

6. The microwave calciner apparatus of claim 1, wherein, The feeding section includes a feeding bin and a buffer fence. The buffer fence is provided at the inlet of the feeding bin, and the outlet faces the uppermost conveying mechanism, so that the tailings material in the feeding bin can slide from the feeding bin to the uppermost conveying mechanism by its own gravity.
7. The microwave calciner apparatus of claim 1, wherein, Also includes: A gas processing system includes a first processing tank, a second processing tank, and a negative pressure fan connected in sequence. The air inlet of the first processing tank is connected to the top of the furnace body and is lower than the air outlet of the first processing tank. The air inlet of the second processing tank is lower than the air outlet of the second processing tank.
8. The microwave calciner apparatus of claim 7, wherein, The first processing tank further includes an inlet and an outlet, with the inlet being higher than the outlet.
9. The microwave calciner apparatus of claim 1, wherein, The discharge section includes: A spiral conveyor is inclinedly mounted on the furnace body, with its inlet located at the end of the lowest conveying mechanism and its outlet outside the furnace body and above the inlet.
10. The microwave calciner apparatus of claim 1, wherein, The feeding section and / or the discharging section are also equipped with dust removal spray components.
