EcoBell2 SL EC - Rotating Atomizer with External Charging
Operating principle

As of:: 01/2020
The mixed paint can only be used for a limited time (can time). When
this time expires, the material starts coagulating. Coagulated material
blocks the nozzle and lines. The atomizer must be rinsed more
frequently.
A T T E N T I O N
Risk of damage to property and production disruption
Quick-drying 2K paints clog the recirculation line in a short time.
Do not use atomizers with recirculation for quick drying 2K paints.
Quick-drying 2K paints contain:
- Isocyanate based hardeners
- Epoxy resin based hardeners
Do not use isocyanate based and epoxy resin based hardeners with
2K atomizers.
Hardener and main paint must be mixed outside the atomizer. An
external mixer is therefore available (see chapter “Optional
accessories”).

4.4.1
Bell disk
The bell disk is mounted on the hollow turbine shaft and rotates with
the shaft.
The stationary paint pipe is located in the hollow turbine shaft. Paint
flows through the paint pipe into the rotating bell disk.
From inside the bell disk, the paint escapes through the gap between
bell disk and distributor disk (plastic) at the center of the bell disk.
Part of the paint also leaks through the hole in the center of the disk.
The paint is distributed uniformly in the bell disk:
- 80% from the gap
- 20% from the hole
Through the rotation, the paint is pushed to the edges and atomized.
