Particle Size Analyzer PSM-500

The Thermo Scientific™ Particle Size Analyzer PSM-500 helps optimize energy efficiency while enhancing mineral recovery and quality in a cement, coal or mineral plant. The PSM-500 utilizes an ultra-sonic attenuation technique and supplies a minute-by-minute analysis of particle size distribution, which is used in grind control optimization to ensure that over or under grinding does not occur.

The rugged on-line particle size analyzer pulls its own continuous sample using a vacuum educator. To assist with the ultrasonic measurement, the sample is de-aerated in the sample conditioner before it passes between diametrically opposed ultrasonic sensors and is returned to the process.

The Thermo Scientific™ Particle Size Analyzer PSM-500 provides real time, in-stream particle analysis of up to three streams, measuring up to nine particle size fractions simultaneously.
