Product Overview

The combined water and gas atomization system is designed for industrial-scale metal powder production under atmospheric conditions. By combining gas and water atomization in a two-stage process, the system enables efficient powder production with adjustable particle size, morphology, and particle size distribution.

Working Principle

Metal or alloy feedstock is melted under a protective atmosphere and flows through a heated tundish and delivery tube. High-pressure gas first breaks the molten metal into fine droplets, which are then further fragmented by high-pressure water. Rapid cooling during flight promotes solidification, producing fine metal powders with spherical, near-spherical, or irregular morphologies.

This combined atomization process integrates the advantages of gas and water atomization to support efficient production and flexible control of powder characteristics.

Key Features and Advantages

1. Durable Equipment Structure: Non-magnetic stainless steel construction provides high mechanical strength and long service life.

2. Precision Pouring Control: A fixed furnace pouring outlet supports stable, high-precision pouring.

3. Efficient Melting and Heating: Rapid melting and heating improve production efficiency and help achieve a consistent particle size distribution.

4. Hydraulic Tilting Furnace: Stepless speed adjustment enables controlled furnace tilting for stable and safe operation.

5. Digital Process Monitoring: Digital display and monitoring of atomization water height support stable control of key process parameters.

6. Integrated Control System: A distributed control system, video monitoring of key components, and a user-friendly human-machine interface simplify equipment operation and process monitoring.

Adjustable Powder Characteristics

Powder particle size, morphology, and particle size distribution can be tailored by adjusting the atomization process and key operating parameters.The main influencing factors include:

A. Alloy Properties: Molten metal viscosity and surface tension.

B. Atomization Pressure: Water and gas atomization pressures.

C. Metal Flow Rate: The alloy flow rate, determined by the nozzle orifice diameter.

D. Nozzle Geometry: The structural design and geometry of the atomizer nozzle.

Adjusting these parameters allows the production process to be adapted to different alloy properties and powder requirements.

Production Process

Raw Materials → Melting → Atomization → Flourishing → Centrifugal Dehydration → Drying → Reduction → Crushing → Screening → Batch Blending → Finished Product Packaging. 

During centrifugal dehydration, the specified water content is 5–15%.
