DF-MPSI particle size analyzer


DF-MPSI particle size analyzer is an online slurry particle size analysis system that monitors the grinding and grading process in mineral processing. It can automatically sample up to 4 process flow channels and measure slurry particle size within the range of 25-1000 microns (15-500 mesh). The analyzer transmits the analysis results to the on-site automation system for real-time process monitoring, ensuring continuous operation 24 hours a day with minimal maintenance.

The principle is direct particle size measurement,it is not sensitive to changes in characteristics such as bubbles, slurry viscosity, magnetism and temperature.

DF-MPSI can detect up to 4 different slurry flow channels for different processes, each channel can achieve multiple particle size measurements.

Regular automatic zero point calibration to compensate for drift and monitor sensor wear to ensure high-precision detection.

Intelligent diagnosis and remote monitoring function reduces manual maintenance and effectively reduces maintenance costs.
