Filter Bags- Smelter
Alumina dust is very fine and abrasive and requires state-of-the-art filter media. The industry spends a great deal of capital on baghouse maintenance and equipment that monitors baghouse performance.
Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself.
Zinc smelting and product recovery are challenging applications because of the chemical makeup of the gas stream, temperature excursions, and characteristics of particles and dust cake.
During the production of copper in the smelt furnace, dust is normally captured in the baghouse as a means of air pollution control.
The prefixed, lumpy sinter is then loaded into the top of a heated blast furnace, along with the coke fuel.
