On the right, a labeled diagram of the vacuum chamber's internal components, stacked top to bottom: thermocouple, rams, die supports, punches, and a central induction coil surrounding the die. Dashed red lines connect the diagram labels to the corresponding parts in the photograph.
  • Dynamic picture analysis of powders and loose bulk solids (granules, fibers)
  • Robust and reliable device for precise and quick measurements (several thousand to millions of particles)
  • Particle size analysis from 1 µm to several millimeters
  • Detailed 2D-analysis of shape characteristics (anisotropy, sphericity, symmetry)

Compact rectangular GranuDrum powder flow analyzer with a window and handle on a table next to a monitor displaying software.

Selected features:

  • Compact ultrasonic atomizer for a wide range of metal alloys including Ti-based or other reactive metal materials
  • Highly spherical metal powders suitable for material development in the field of additive manufacturing (powder bed fusion, deposition welding)
  • Flexible machine setup for the atomization of wire or bulk (rods, several millimeters diameter)
  • Low operating costs and high efficiency
