Rotary Calcining Furnace

Features of Rotary Calcining Furnace :
* The move-asleep sealing joint is made of graphite ring with spherical surface,having good seal reliability.
* The heating elements are hanged on three sides of the hearth,making temperature uniformity.
* The refractory lining is made up of fibre blankets with good heat preservation.
* Atmosphere:H2,N2 or Air,0-10Kpa.
* Raw material is feeded into the drum by a dosing screw feeder,and the finished product is discharged automatically by a two-valve mechanism.
* The rotating speed of the drum and helix can be step-less-changed.
* The raw material in the furnace contacting with process gas enough and equably, it is a perfect type of furnace to produce uniform and fine pure metal grain.

Applications:
As a calcinatory,Ammonium tungstate and ammonium molyvdate can calcened in it to produce tungsten oxide and molybdenum oxide.
As a reducing furnace,tungsten oxide or other metallic oxide powder can be reduced in it with H2 to priduce tungsten or other pure metal.
