Precision Rotary Disk Atomization Systems & Centrifugal Wheels
AKSH Engineering Systems Pvt. Ltd. is a leading manufacturer, supplier, and global exporter of high-efficiency Rotary Disk Atomization Systems based in Ahmedabad, Gujarat, India. Engineered to convert high-viscosity liquid feeds, abrasive slurries, and heat-sensitive liquids into uniform droplet sprays, our centrifugal disk atomizers deliver exceptional droplet size uniformity, low power consumption, and long operational life in demanding spray drying applications.
Whether you are handling dense agrochemical formulations, pharmaceutical extracts, food-grade concentrates, or mineral slurries, AKSH Engineering custom-designs rotary disk atomization setups engineered to match your exact feed viscosity, rotational speed, and processing throughput requirements.
What is a Rotary Disk Atomizer?
A Rotary Disk Atomizer (also referred to as a rotary disc atomizer or centrifugal atomizer) uses high-speed rotational force to atomize liquid feeds into ultra-fine droplets. Liquid is introduced onto the center of a rapidly spinning disk or wheel. Centrifugal force propels the liquid outward across the surface of the disk, shearing it into a thin film that breaks apart into uniform micro-droplets as it leaves the periphery.
Unlike pressure spray nozzles, rotary disk atomizers operate without small fixed orifices in the atomization zone. This open-surface design prevents clogging and backpressure issues, making centrifugal disk atomizers the preferred choice for high-solids feeds, suspensions, and viscous liquids.
Principles of Centrifugal Atomization
The droplet sizing and spray characteristics of our rotary disc atomizers are governed by precisely controlled fluid dynamics:
-
Rotational Speed (RPM): Higher disk speeds generate greater centrifugal force, producing finer droplet sizes. AKSH atomizers feature Variable Frequency Drives (VFD) allowing operators to adjust speeds up to 25,000+ RPM for exact droplet control.
-
Liquid Feed Rate: The liquid volume delivered onto the disk determines film thickness at the edge. Our integrated liquid distribution manifolds ensure a stable, pulse-free feed for consistent atomization across varying flow rates.
-
Disk Geometry & Surface Vanes: Disk diameter, surface profile, and internal vane configurations dictate liquid velocity and throw patterns. We engineer custom straight, curved, and pin-type disk profiles tailored to specific slurry dynamics.
-
Fluid Viscosity & Surface Tension: Viscous or non-Newtonian feeds require specialized disk metallurgy and drive torque. Our designs handle broad viscosity ranges without stringing or uneven droplet dispersion.
Key Advantages of AKSH Rotary Disk Atomization Systems
1. Superior Droplet Uniformity
Our dynamically balanced atomizer wheels produce a narrow droplet size distribution spectrum. This consistency is critical in spray drying processes, where uniform particle sizing directly dictates final product bulk density, solubility, and moisture content.
2. High Resistance to Clogging & Fouling
Because atomization occurs along the open rim of a spinning disk rather than through narrow nozzle tips, our rotary disk atomizers are virtually immune to clogging—even when processing liquids with suspended solids or high crystal concentrations.
3. Wear-Resistant Metallurgy
To resist severe abrasive erosion from mineral, ceramic, or metallic slurries, AKSH manufactures disk components with hardened alloys (SS316L, Duplex SS, Hastelloy) and applies tungsten carbide or technical ceramic inserts along high-friction flow channels.
4. Low Maintenance & Extended Bearing Life
Every rotary disk assembly is dynamically balanced to precision industrial standards. Low vibration levels protect high-speed drive spindles, bearings, and seals, drastically reducing downtime and routine maintenance expenses.
