Conical Dryer Blenders (CDBs)

Glasteel®, (glass-lined) Conical Filter Dryer for an API Glass-Lined Conical Dryer Blender

The Pfaudler (CDB) combines an unusual design with a unique material of construction into a unit that uses heat, vacuum, and a gentle tumbling action to dry and blend even the strongest corrosives. The double inverted cone vacuum dryer design ensures a thorough mix and a homogeneous product so that drying is both controlled and fast.

How the CDB Operates

Once the product is fed into the manhole to the desired capacity, clamps seal the cover and rotation begins. As the CDB revolves, the top layer of the product rolls down toward the opposite cone and is followed by the entire mass. The conical walls deflect the product toward the center producing a constantly changing cross section of material that blends as it dries. The jacket surrounding the vessel contains a heating medium that is circulated by means of a rotary joint or through the center of the support shaft. A vacuum tube removes vapors formed by the heated jacket.
