Rotary Atomizer Type FS15
The atomizer drive consists of two parts. The top part includes the motor and its support. The motor is a 2-pole, high frequency/high speed, vertical flange type, and the power is transmitted from the motor to the spindle via a flexible coupling. The lower part of the atomizer comprises the support for the spindle bearings, feed pipe assembly, and the conical protective skirt. The drive is designed according to the flexible spindle concept, so that the irregularities in the feed rate and other minor imbalances in the atomizer wheel can be compensated without spindle and bearing damage.
The monitoring system includes:
- Spindle vibration alarm as protection against excessive vibration conditions (optional for heavy duty applications)
- Flooding alarm as protection against feed leakage on the supporting plate
- Tachometer to register variable spindle speed adjusted by control of frequency converter (optional)
- Ammeter and running hour-meter installed in the spray dryer control panel to indicate operating performance

All parts of the atomizer exposed to feed and product are fabricated in stainless steel and comply to the hygienic requirements stated in US 3-A, EN 1672-2, and similar national sanitary directives.
The atomizer wheel
The FS15 atomizer can operate with either a channel or nozzle type (for non-abrasive feed) or an insert type (for abrasive feed) wheel of 150 mm diameter.
The channel wheel is equipped with either 36 high straight channels or 16 high curved channels. The straight channel wheels are used in situations where there are no specific requirements of bulk density in the final product. The curved channel wheels produce higher bulk density (higher than on a straight channel wheel) in case of organic products.
The nozzle wheel is equipped with eight bushings. If the steam is introduced into the wheel body, it may result in powders with higher bulk density in case of organic products. The patented design of the insert type wheel consists of eight inserts. The wheel parts exposed to feed are abrasion-resistant and easily replaceable. The conical inserts and a bottom plate of the stainless steel wheel are made from alumina or advanced ceramic material.
