Multiple Hearth Furnaces
The FGC Multiple Hearth Furnace consists of a series of circular hearths, placed one above the other and enclosed in a refractory-lined steel shell. A vertical rotating shaft through the centre of the furnace carries arms with rabble blades which stir the charge and move it in a spiral path across each hearth.

Multiple Hearth Furnace Mineral Roasting Technology
The main types of roasting furnaces include multiple hearth furnaces (MHF), rotary kilns, fluidized roasting furnaces, floating roasting furnaces, sintering machines, and vertical roasting furnaces. The MHF was developed by Nichols Corporation in 1890 for roasting pyrite. In 1931, China imported the first MHF used for roasting tungsten ore.
