Benefits of Fluidizing Powder Hopper

A hopper feed powder coating gun holds the powder in a sealed hopper that has a fluidizing plate on the bottom. This fluidizing plate constantly fluidizes the powder so that it flows around inside the hopper. This process is called fluidization.

When you look at the top surface of the powder in a powder coating hopper that is being fluidized by compressed air, it should look like it is boiling. If you put your hand in the powder while it is being fluidized, it should feel silky smooth.

The fluidized powder is easily to be conveyed from the hopper to spray gun with a high degree of uniformity and consistency. Fluidizing action breaks up powder accumulation, removes absorbed moisture, improves powder coating quality.
