*Work theory:

  It is dried by two steps. Firstly, the materials will be plus-pressure dried by drying tail gas and complement hot air, the used tail gas with high temperature and low humidity will be discharged out, the dried materials will be dried again by the hot fresh air and its tail gas will be used in the first dring, which realize the circulated drying. So it can be widely used.

*Application:

  It is widely used for all kinds of materials including methaqualone, A.B.C resin, A.B.C white carbon, A.B.C intermedia, catalyzer of oxalic acid, accelerant m.d.m, carbon powder, para-acetamidobenzene sulfonyl chloride, parasal, terephthalic, titanium dioxide, activated carbon, sodium fluosilicate, fluorite, silica powder, ammonium sulphate, compound resin, calcium hydrophosphate, polyprolene resin, aureomycin, sodium silicate, oral glucose, sodium sulfate, phosphorite powder, BB, PVC, fertilizer, cheomycin, ferric tri-oxide, calcium carbonate, ilmenite, copper, dtearate, corn protein, medicine, feeric oxide, etc.
