During the operation of the FL Fluidized Bed Granulator Dryer, powder particles circulate in a stable toroidal flow pattern within the fluidized bed. Purified hot air preheats and mixes the material while an atomized binder solution is precisely sprayed into the chamber, causing the particles to form agglomerates. As hot air continuously removes moisture, the binder solidifies, producing uniform, microporous spherical granules through repeated cycles.
The efficiency and stability of this granulation process depend heavily on precise airflow distribution, structural sealing, and component cleanliness. For critical parts-including air distribution plates, spray nozzle assemblies, bed cavity interfaces, and sealing flanges-Hansheng Automation provides high-precision custom machining based on customer engineering drawings. We strictly utilize industry-standard 316L or 304 stainless steel, maintain tight geometric tolerances within ±0.01 mm, and offer surface mirror polishing up to Ra ≤ 0.4 μm to eliminate material residue and uneven air distribution.
Because different materials vary in thermal sensitivity and stickiness, optimal granulation relies on uniform contact area and temperature control. Hansheng Automation manufactures custom non-standard components to client specifications, helping optimize gas flow channels and spray angles. This effectively prevents local overheating and caking common in traditional drying, significantly accelerating moisture evaporation and binder curing.
In the pharmaceutical, food, and fine chemical industries, specialized components for FL granulators must meet stringent wear resistance, corrosion resistance, and high-cleanliness standards. With strong draw-to-order and small-batch precision machining capabilities, we deliver rapid, high-quality custom component solutions tailored to equipment wear or process modification needs, ensuring stable and efficient production line performance.
