On-line Powder and Pellet Analysis
Some typical applications are:
  • Raw meal optimization in cement plants (SiO2, CaO and Fe2O3)
  • Finished cement analysis (SO3)
  • Sb, Br, and Zn in polystyrene pellets
  • NaCl in Methyl cellulose
  • Fe and K in feldspar
  • Catalysts and additives in Polyethylene and Polypropylene (Ti, Ca, Zn)
You present us with the analytical problem and we give you the solutions. SPECTRO offers you a choice of two different analyzers that can be packaged to suit exactly your powder or pellet application.

Gravity Powder Sampler

A measuring head mated to a chamber filled with powder. The chamber is filled, packed by vibration, analyzed, emptied, and then refilled.

Reciprocating-Arm Powder Sampler

A measuring head placed over a moving arm that extends into a product chute to collect a sample.

Gravity Packing, Model 600(T)-G
  • Well proven vertical sampler with 40mm diameter sample cell with polished stainless -steel inner surface.
  • Proprietary X-ray window designed for long service life.
  • Optional window break sensor.
  • Optional vibrating sample packing device for reproducible sample density.
  • Measuring head mechanically isolated from vibrations.
  • Hinged measuring head mounted for quick and easy access to optics.
  • Optional analytical purge for improved light element measurements.
  • Optional manual check-sample collection assembly.

Reciprocating Arm, Model 600(T)-RA

This configuration employs a novel reciprocating arm to collect samples from a vertical chute with minimal (or no extra) sample handling equipment; coupled with automatic pellet production and "windowless" analysis, the 600T-RA affords unmatched ease and simplicity of on-line analysis.

  • Small measuring assembly installs on the side of any suitable chute or air sluice.
  • Automatic, motor-driven arm usually does not require pre-sampler.
  • Integrated sample cup, sample pellet-press and pneumatic pellet-discharge system for verification.
  • Hinged measuring head mounted for quick and easy access to optics.
  • The XRF measuring head is isolated from vibration.
  • The need for a special beryllium X-ray window is eliminated by the downward facing XRF geometry which improves light element performance and reduces maintenance.
  • Optional analytical purge improves light element measurements.
