SIZESCAN PSD

Particle size affects crushing performance, mill feed stability, energy use, recovery and product quality. SizeScan PSD continuously measures particle size distribution and flow on the conveyor, helping operators identify changes in blasting, crushing, screening or grinding performance before they become larger production problems.

Key Benefits

Maintain consistent product sizing and quality

Reduce reliance on manual sampling and sieve analysis

Detect changes in particle size distribution early

Enable data driven operational decisions

Support optimisation of crushing and grinding circuits

Proven Performance

The SIZESCAN PSD is designed for mining, minerals, quarrying and bulk materials handling applications

Continuous operation in demanding industrial environments

Non contact measurement with no interference to material flow

Reliable performance in dusty operating conditions

Supported by a global service and support network

Technology

SizeScan PSD uses advanced 3D infrared camera technology and proprietary imaging algorithms to measure particle size distribution and material flow across the conveyed stream. The system reports continuous P-values such as P80, P50 and P20 and can be calibrated against belt cut sieve analysis for site-specific performance.

Applications

Typical applications include:

  • Run of mine feed monitoring
  • Crusher performance monitoring
  • SAG and AG mill feed monitoring
  • HPGR feed monitoring
  • Product sizing verification
  • Stockpile and blending optimisation

Role in Process Control

The SIZESCAN PSD operates as part of a broader measurement and control strategy within mining and mineral processing operations.

It enables:

  • Feed forward control of crushing and grinding circuits
  • Feedback control of upstream blasting and crushing operations
  • Continuous monitoring of particle size distribution
  • Improved process efficiency and product quality management
  • Continuous decision support for operators managing process variability

Unique Capabilities

  • Simultaneous particle size distribution and flow measurement
  • Continuous P value reporting including P80, P50 and P20
  • Simple installation directly onto conveyor stringers
  • Web based interface and reporting tools
  • Calibrated against belt cut sieve analysis for site specific performance
  • Single calibration only following installation
  • Measures particles from 7mm upwards in size
