DF-PSM Online Ultrasonic Particle Size Monitor is an on-line slurry particle size analyzer. It can provide accurate and real-time on-line particle size analysis of slurry and is suitable for measuring particle size distribution from 25 μm to 295 μm in accordance with P80 standard. By using the feedback information of the instrument, the grinding circuit can be optimized, so as to improve the product quality, improve the recovery rate and reduce the energy consumption.
DF-PSM Online Ultrasonic Particle Size Monitor generates a relatively stable and representative slurry flow through the sample conditioning unit, which is degassed. After degassing, the slurry is detected by ultrasonic attenuation measurement unit with ultrasonic transducer as the core component, and finally the slurry sample returns to the original process pipeline. During the measurement period, the probe transmits ultrasonic energy pulses at various frequencies through the sample and obtains multiple attenuation parameters from the received ultrasonic pulses. These parameters are directly related to the particle size distribution density of slurry samples. In the calibration model of each particle size, these parameters are used as variables to calculate the slurry concentration and particle size.
DF-PSM Online Ultrasonic Particle Size Monitor system mainly includes: DF-PSM Online Ultrasonic Particle Size Monitor (standard configuration) and multi-channel converter. At the same time, according to the on-site process pipeline layout, slurry distribution boxes with different channels (including drainage and return pipes) are to be selected.
