Introduction to Powder Coated Fluidized Bed:
For powders with a diameter of less than 100 μ m, due to their small particle size, high surface energy, and strong intermolecular forces, traditional fluidized bed bottom spraying coating is prone to agglomeration, resulting in agglomeration fluidization and inability to achieve powder coating. To address this type of powder, we have introduced a composite fluidized bed with the following core points: 1. A high-speed turntable with a stirring structure at the bottom, which uses mechanical energy to move animal materials in a circular motion, effectively preventing the phenomenon of powder agglomeration caused by a single kinetic energy like traditional fluidized beds; 2. The bottom side spray gun is buried at a certain angle in the material for liquid spraying. The coating material has a high utilization rate and a large contact area, effectively preventing the occurrence of low utilization rate and easy adhesion of fluidized coating liquid like traditional guide tubes; 3. The rotating and dispersing screening structure makes the coating particle size more uniform, with higher reproducibility and process stability. For this purpose, two models are specifically divided: the MP model is designed for coating powders larger than 80 μ m, and the SFP model is designed for coating powders smaller than 80 μ m.
