What is a rotary atomizer? An atomizer is an atomization apparatus. In the manufacturing process, fine powder is produced by spraying molten or dissolved materials through an atomizer and solidifying the droplets.
The rotary atomization process Atomizing solution means to pulverize something into very tiny pieces. Atomization is conversion of bulk liquid into a spray or mist (i.e. collection of drops) through a high speed atomizer. Despite the name, it does not usually imply that the particles are reduced to atomic sizes.
GEA Niro rotary atomizer solutions
GEA Niro produces a large range of rotary atomizers, from portable, units through to large-scale industrial production units. Currently, 12 patented model types are available, and the most commonly used sizes are:
Rotary Atomizer F1.5X
Benefits of GEA Niro rotary atomizers
• Long lasting, heavy duty designs
• Patented atomizer wheel designs
• The atomizer parts exposed to feed comply with US-3A and other, similar national sanitary directives.
Rotary atomizer monitoring system comprises
• Low oil pressure alarm
• High and low oil level alarm
• High oil temperature alarm
• Flooding alarm protecting against feed leakage
• Spindle vibration alarm protecting against excessive vibration conditions
• Tachometer to register spindle speed when adjusted by control of a frequency converter.
The rotary atomizer drive
There are two different types of atomizer drives:
• Gear driven
• Direct driven
The gear driven atomizers uses food approved oil for lubrication of gears and bearings. The directly driven atomizers are driven by high speed motors and are equipped with double sealed ball bearings greased for life to avoid any kind of oil or grease contamination in the final product.
The rotary atomizer wheel
The patented design of insert type wheel selection depends upon the operating specifications. Basically there are two types:
• The channel wheels
• The abrasive resistant wheels
The straight channel wheels are used in cases where there are no specific requirements of bulk density in the final product. The curved channel wheels produce higher bulk density (higher than with a straight channel wheel) in case of organic products.
The abrasive resistant wheels are used for products that expose the wheel to hard wear, such as fluid gas cleaning, mining industry, hard metals and silica.
