SDX® Spray Drying Nozzle

SDX® Spray Drying Nozzle features a hollow cone spray pattern with uniform particle size distribution, fine atomization, and reduced operating pressure requirements for spray drying applications.

Spray Angle:
45˚ — 90˚
Spray Pattern:
Hollow Cone
Flow Rate:
Variable

Description

SDX® Spray Drying Nozzle produces a hollow cone spray pattern with uniform particle size distribution, even at low operating pressures. Designed for spray drying and atomization applications, the SDX® Spray Drying Nozzle utilizes a patented single-inlet swirl chamber that improves product uniformity, particle density, and solubility. The optimized swirl chamber design reduces friction losses, allowing operation at lower pressures than conventional slotted distributor nozzles while extending pump and nozzle life. Multiple material combinations are available to suit demanding process conditions and operating environments.

Spray Characteristics:
Produces a hollow cone spray pattern with uniform particle size distribution and fine atomization over a wide operating range. Flow rates are controlled within ±5% of rated capacity at 69 Bar.G and within ±5° of rated spray angle. The patented single-inlet swirl chamber improves product uniformity, density, and solubility while reducing operating pressure requirements by approximately 10-20% compared with conventional slotted distributor designs.
Construction and Materials:
Eight-part construction consisting of body, body seal, orifice seal, orifice disc, swirl chamber, end plate, screw pin, and adaptor. Nozzle bodies, screw pins, and adaptors are manufactured in 316 Stainless Steel and are available from hexagon bar stock. Orifice discs are available in Tungsten Carbide, Chrome Carbide, and Ceramic. Swirl chambers are available in Tungsten Carbide, Hardened Stainless Steel, and Ceramic. End plates are available in Tungsten Carbide, Chrome Carbide, and Ceramic, with a combined Tungsten Carbide swirl chamber/end plate option also available. Seals are available in Nylon, PTFE, Copper, Hard Fibre, and Aluminium. The modular design allows easy replacement of wear components while supporting long service life and optimized spray performance.
Maximum Recommended Pressure:
500 Bar.G.
Ordering Instructions:
Please indicate all component parts and materials when ordering.

Assembly Procedure:

  1. Place Nozzle Body (A) thread side up on a flat surface
  2. Place Orifice O-Ring (B) in the Nozzle Body (A)
  3. Place Orifice Disc (C) on top of the Orifice O-Ring (B)
  4. Place Swirl Chamber (D) on top of Orifice Disc (C) either way up
  5. Insert End Plate (E) over Swirl Chamber (D) beveled side up
  6. Install Screw Pin (F) into Nozzle Body (A), wrench until snug (Torque of 47.5 Newton/Meters or 35 Pound-feet)
  7. Drop Body O-Ring (G) onto Nozzle Body (A)
  8. Screw Nozzle Body Assembly onto Adaptor (H), wrench until snug (Torque 68 Newton/Meters or 50 Pound-feet)
  9. Finally, ensure the complete assembly does not rattle
