## Setting of atomizing air volume

The air volume of the fluid bed dryer granulator can be adjusted by adjusting the spray gun adjustment cap. The air volume increases when it rotates counterclockwise, and decreases when it rotates clockwise. The atomization angle of the spray increases with the increase of air volume.

The influence of this factor: large air volume, uniform atomization, and small mist particles.

## Setting of adhesive dosage

The adhesive dosage in the fluid bed dryer can be adjusted by adjusting the speed of the infusion pump. The speed of the pump is adjusted by the voltage speed knob.

The influence of this factor: the larger the flow rate, the more uneven the atomization, and the coarse the mist particles.

## Air pressure

The air pressure is adjusted by the pressure reducing valve, generally 0.2~0.4Mpa.

The influence of this factor: high pressure leads to uniform atomization and fine atomization.

## Spray gun opening

When operating the fluid bed granulator, turn on the atomizer first and then the spray gun. When closing, turn off the spray gun first and then the atomizer.

## Cleaning

After each use of the spray gun, use 2-3Kg of hot water to start the pump and thoroughly clean the spray gun and other fluid bed dryer parts.

## Binder treatment

After the binder is configured, it must be strictly filtered through a 40-mesh screen to prevent block materials from entering the spray gun and causing blockage in the fluid bed granulator. At the same time, the spray pipe should be blown clean with compressed air.

## The Nozzle Should Be Well Protected

Proper protection of the nozzle is essential for the long-term performance of the fluid bed dryer.
