Cement, Coal, Minerals

The Thermo Scientific™ Particle Size Analyzer PSM-500 provides accurate feedback for the optimization of grinding circuit performance helping customers not only to enhance mineral recovery and quality but also to optimize their energy efficiency during the process. This unit is a rugged on-line Particle Size Analyzer which pulls its own continuous sample using a vacuum eductor. 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.
