Rotary Tube Furnace Line for Rare Earth Metals

tmax up to 650 °C

Rotary tube furnace line, Tmax up to 650 °C, up to Ø1800 mm, L 10800 mm, output up to 2 m3/h, incl. conveyor and goods comminution

Applications:

calcination, drying, oxydation, pyrolysis, reduction, thermal recycling

Furnace line for manufacturing of rare earth metals consisting of a rotary tube furnace (FDHK-5-1400/10800/550) for drying and calcination, a rotary tube furnace (FDHK-5-1800/10800/550) for sulphatisation and a rotary tube cooler (DHK-1800/5500/100) for cooling.

Other possible applications are: 

Drying, calcination, heat treatment of bulk goods (powder, granules …) and slurry 

Pyrolysis (f.ex.  waste, biomass) 

Active coal production
