Optical Microscopy

Grinding Solutions use the ZEISS SteREO Discovery.V8 microscope with AxioVision software for optical microscopy analysis. The system allows detailed quantitative analysis of ceramic grinding media characteristics including sphericity and particle size distribution.  Performing the analysis pre and post wear in conjunction with our wear test can give the client a detailed insight into poorly performing media by identifying the following issues:

  • Mechanism of media wear
  • Changes in sphericity
  • Changes in size distribution

This is extremely useful in identifying and helping to resolve outstanding issues with media wear.  It can also be used as a quality control tool, identifying deformed media or media with incorrect size distributions in fresh media samples.

The system is also capable of visualising particles down to approximately 50 µm for preliminary evaluation of mineral samples and has also proven to be a useful tool in identifying unexpected material in samples provided by clients.

Particle Size Analysis

Grinding Solutions offer particle size analysis using the Malvern Mastersizer 3000 laser diffraction technology. With a measurement range of 0.01 – 3000µm, the system is ideally suited for mineral processing applications.  The system is used regularly at Grinding Solutions for applications such as sizing signature plot samples, ultrafine industrial mineral samples, optimising classification techniques and verifying particle size distributions for other laboratory testing when required.  Analysis can be tailored to the needs of specific projects/ material with the comprehensive Mastersizer software.

Chemical Assays

Grinding solutions use a handheld Olympus XRF for indicative assay results on test work. We work closely with a number of analytical laboratories to provide chemical analysis to specifically suit every project.  Together with our professional partners we can provide a wider range of chemical assays covering all aspects of base metals, precious metals, carbon, sulphur and industrial minerals analysis.Save
