APSON spraying bells are high-speed rotators for yielding and fine dissipation of liquid media. Typical media are normal lacquers, metalic lacquers or other aggressive liquids, e.g. solvents.

APSON spraying bells are rotationally symmetrically developed. They usually consist of at least two parts - the front part and the coat.

The front part usually consists of polished inoxidable steel, aluminum, titanium or plastic. It has also the task to connect the spraying bell anti-swiveling with the shaft as well as to lead the medium in a thin layer to the edge of the spraying bell during the application. The edge of the spraying bell can be executed knurled or smoothly. There are spraying bells for turbines with hollow or full rotor shaft.

The coat consists usually of lighter material, e.g. aluminum or plastic. It has the task to determine the flow conditions of the air in direct proximity of the spraying bell.

During the application, at the spraying bell is applied a high Direct Current Voltage from -40 to -80 Kilovolts, referred to earth potential (0 Volt). The objects which are to be sprayed are held on earth potential.

At rated speed from 40,000 to 60,000 revolutions per minute the electrically charged medium yields through the center of the front surface.

Because of strong centrifugal forces the medium flows over the edge of the front surface into the strongly whirling ambient air. Due to the detachment of the medium, from the edge of the bell fine negatively charged medium droplets are generated.

If the medium was sufficient strongly loaded, the droplets shatter in the air into a still smaller medium fog. This fog is attracted by the object to be sprayed due to the dominant electrical field. In this way the fine spray deposits even on those object surfaces that are turned away from the bell.

APSON has experience of many years in the production and repair of spraying bells for electrostatic painting. There are the following Ordering options:

• New Spraying Bells
• Compatible Spraying Bells
• Repared Spraying Bells

New spraying bells can be manufactured according to specification of the customer. Condition is a Written Explanation of the Customer that he has copyrights or manufacturing rights of the respective spraying bell or bell type.

Alternatively APSON develops and produces inexpensive and high-quality Compatible Spraying Bells for already existing Plants. These obtain the same high painting quality as the original bells. From arguments of Right they must have however different geometrical dimensions than the originally employed bells.

Furthermore APSON delivres inexpensive and high-quality Repared Spraying Bells. These obtain a similar high painting quality as the new bells.
