PIQ Rock Size Distribution



PIQ Rock Size Distribution is a laser-based online particle size analyser (PSA) system that provides a real-time particle size distribution (PSD) as well as total volumetric flow.  A quantitative estimate of very fine material, which is important to keep in balance with the coarse material to ensure optimal mill performance, is made possible by comparing the total volume to the segmented volume.

Milling Circuit

Below is a typical milling circuit where this is installed on the belt to measure ore particle size distribution.


  • Continuous visibility on the product state enabling efficient, real-time monitoring and quality control
  • Flag under loading/overloading and uneven loading
  • Monitor fleet efficiency
  • New PSD every 4-10 seconds
  • More cost-effective compared to individual truck based load cells
  • Industrial cameras / profile lasers
  • Housing IP67
  • Camera-based standard with powerful LED lights
  • Laser sensor requires no floodlights = more robust & less maintenance



  • PSD/Volume/Oversize
  • Primary crusher blast fragmentation feedback
  • Primary crusher oversize protection
  • Ore Characteristics
  • Screening efficiency
  • Product quality
  • Reduction rations, wear and gap settings


  • PSD/Volume/Oversize
  • Mill fill estimation
  • Ore Characteristics
  • Blending
  • Milling efficiency

  • Various image processing techniques and images for robust PSD
  • Traditional sampling manual, error prone and statistically problematic
  • Multiple commodities including coal
  • ROM with large PSD variations to product streams
  • 60 installed systems, all monitored remotely
  • Robust layer sensors
