Spray Dryer Spare Parts - Nozzle

Description: The nozzle of a spray dryer is the core component that atomizes the feed liquid into fine droplets. It determines drying efficiency, product particle size and flowability, and is a key device affecting final quality and energy consumption.

1. Core Function

Atomization and Surface Area Increase: Break the solution/slurry/emulsion into 10–250 μm droplets, instantly enlarging the contact area, achieving rapid evaporation within 0.1–5 seconds.

2. Structural Form

Main Structure: Swirl chamber, spray core, spray cap, locking nut, with a central air core forming a hollow cone.

3. Common Materials

Tungsten Carbide (WC) is characterized by extremely high hardness (HRA 88–93), wear resistance, and erosion resistance.
