Technical specification

• Feed material: powders, bulk solids, suspensions
• Maximum quantity of material to be sieved: 25 kg
• Measuring range: 25 µm - 125 mm
• Maximum number of fractions: 13 / 9
• Minimum number of fractions: 3
• Amplitude: digital; 0.2 - 2.2 mm
• Sieving: dry and wet

Application

Separation, fractionation, particle size determination of powdery materials and bulk solids.

Technical specification

• Feed material: Powder
• Maximum feed quantity: 6 kg (bronze or steel)
• Classification range: 4 - 200 µm
• Protective atmosphere: argon or nitrogen
• Maximum speed of classifier wheel: 10000 min-1

Application

Flexible classification of powdery materials in small quantities. Separation of powder into fine and coarse powder fractions, especially in the range < 25 µm, where conventional screening methods usually fail.

Technical specification

• Maximum temperature: 2000 °C
• Atomising medium: argon or nitrogen
• Maximum gas pressure: 30 bar
• Maximum gas temperature: 450 °C
• Atomiser nozzle system: free-fall and clouse-coupled atomiser
• Crucible volume: 3 l
• Maximum powder quantity (steel): 22 kg
• Cycle time: 3 - 4 h

Application

Production of new, innovative and specialised metal powders in small batches for research and development:

• Alloys that are not available on the market;
• Precious metals that are usually required in small quantities and where any metal loss must be avoided;
• Powder materials for additive manufacturing (powder-based processes: Laser/Electron-Beam Melting, Laser Metal Deposition) where high purity, sphericity and reproducible particle size distribution are required;
• Small-volume production with the lowest possible cross-contamination and short process time, which cannot be realised in an economically viable way on conventional systems.
