Our laboratories in Victoria and Chicago are equipped with CKIC Automatic Plastometric Indices Determinators or Sapozhnikov Plastometers. These are very good instruments in determining coals expansion or contraction properties – critical of oven-life longevity. The X and Y indices that the Sapozhnikov Plastometer produces are used to predict oven wall pressures as well as a good indicator for coke quality.
A FRICO plastometer in Victoria was used for three decades in the analysis of single coals and sequential blends, complementing petrography in monitoring product and blend consistency, and verifying process variables. It was retired in 2011 after a long tenure.
Frico Plastometer vs Preiser Plastometer
The next-generation Preiser plastometer in South Holland can measure to 180,000+ ddpm’s, which is vital for the accurate characterization of Ultra-Fluid Appalachian high-volatile coals, whose unique characteristics are caused by bitumen-soaked vitrinite , which are highly-fluorescent .
Some three decades ago, it was demonstrated by Creaney, Pearson & Marconi (1980), that it is not the volume of liptinites, but the volume of fluorescing vitrinite that correlates with maximum fluidity measured in Wolgan coal, from near Lithgow, New South Wales. Now, variations in maximum Gieseler fluidity of many West Virginia based coals is directly correlated with fluorescence intensity.
We may be a small family-based business, but our clients are a who's-who of coal mining and steel production. We are proud to provide our best services for each of our clients.
