Large-scale Double Mass Vibrofluidized Bed Dryer

Working Principle:
NGLZ large-scale vibrofluidized bed dryer uses double mass resonancetype structure. Inertia exciter and resonance mass make up a resonatingsystem. The ordinary electrical motor drives the gear exciter through gimbals to produce exciting force. The exciting force is enhanced several times by a resonating spring and acts on the mass to fluidize the material. The material is ejected due to the exciting force. At the same time,the hot air is supplied at the bottom of the vibrofluidized bed and penetrates the material layer,so the material particles get in full contact with the hot air jet and an ideal drying effect is achieved.

1. Inertia exciter and resonance mass make up a resonating unit which reduces the power of electrical motor and saves energy.
2. An ordinary electric motor drives the gear exciter through gimbals to produce exciting force, the electric motor does not participate in vibrations and contacts with the bed directly. So the applied temperature of the vibrating bed is increased.
3. Being installed in front of the dryer, the exciter improves the bearing situation of the entire machine, and one resonating vibrating bed can replace several ordinary (single mass) vibrating beds installed in series. So the costs of equipment and project design are reduced. Simultaneously, the advanced vibration structure guarantees that the bed vibrates synchronously in width and in length. It solves the drift and channel problem in an ordinary double electrical motor driven single mass vibrating bed dryer.
4. Being increased in length and enlarged in area, the large-scale vibrofluidized bed greatly prolongs the residence time of material. This is for deep drying of coarse material. At the same time, the application of vibrations and reduction of the fluidization velocity is advantageous to reduce abrasion and to keep original size and shape of the particles.

Material to be dried:
The application field of large-scale vibrofluidized bed:
1. Copolymers and monomers and other organic matter: MBS, ABS, adipic acid, PAM, acrylamide crystal, Teflon, PF resins, nylon 66, polypropylene resins, terylene slices, PVC.
2. Inorganic salt: ammonium nitrate, ammonium sulfate.
3. Feed industry and fertilizer industry: fermentation feed, puffed pellet feed, organic fertilizers.
4. Waste treatment for environmental protection: wastes and etc.
