Explosion Proof Fluidized Bed Granulation Dryer 3-500kg/batch Pressure Relief Drying Machine

This explosion-proof fluidized bed granulation dryer is fitted with a pressure relief vent to protect personnel in the event of an explosion. Mixing, granulation and drying run in one closed vessel, so the powder is charged once and leaves as dry, free-flowing, multi-porous spherical granules ready for the next process step.

The powdered material is fluidized in a ring and mixed with purified heated air; an atomized binder solution aggregates particles and the hot air continuously dries them into uniform spherical particles, while a pressure relief vent protects the operator.

1. The powdered material is loaded into the raw material container.
2. Purified heated air is introduced, fluidizing the powder in a ring and mixing it with the air.
3. A binder solution is atomized and sprayed into the fluidized bed.
4. Several particles aggregate around the binder into binder-containing agglomerates.
5. The continuous hot air dries the agglomerates, evaporating the moisture and solidifying the binder.
6. The cycle repeats until uniform, multi-porous spherical particles are formed.

• Granulation of granules, pills and powders.
• Drying of pharm, pesticides, feed and fertilizers.
• Drying of catalysts.

The pressure relief vent and the antistatic filter cloth are the two safety features that matter most when granulating fine powders. Batch capacity, construction material and control configuration can be matched to your process; please share your requirements for a tailored solution.
