DF-PSM ultrasonic on-line particle size analyzer is dedicated to the detection of slurry particle size in the mineral processing industry. It is used to measure the overflow slurry of the cyclone or classifier in the beneficiation process. It is suitable for measuring the particle size distribution from 25 microns to 295 microns that meets the P80 standard. The analysis result is accurate and real-time. Cooperating with the on-site automation system, using the instrument's particle size measurement and analysis information, the grinding circuit can be optimized, thereby improving the quality of the beneficiation products, increasing the recovery rate and reducing energy consumption. The instrument has strong adaptability and can be widely used in solid-liquid two-phase suspension slurry such as iron ore slurry, molybdenum ore slurry, copper ore slurry, gold ore slurry, lead-zinc ore slurry.

The DF-PSM ultrasonic online particle size analyzer adopts the principle of ultrasonic transmission attenuation to analyze the particle size distribution of solid particles in the slurry in real time and realize concentration analysis at the same time. The instrument generates a relatively stable and representative slurry flow of vacuum suction through the sample conditioning unit, which is degassed to ensure that the measurement accuracy is not affected by other on-site interference conditions such as bubbles, and has strong adaptability. The degassed ore slurry undergoes transmission detection through an ultrasonic attenuation measuring unit with an ultrasonic transducer as the core component, and the measurement signal passes through all the ore samples, which is highly representative. The final slurry sample is returned to the original process pipeline, which will not cause the consumption of raw ore resources. During the measurement period, the meter uses multiple ultrasonic signals of different frequencies to perform ultrasonic attenuation measurement of the slurry. These operating frequencies are customized according to the concentration and particle size range of the slurry to be tested, and are designed according to specific algorithm patents. The ultrasonic attenuation coefficient constitutes a calibrated model, which can reflect both the coarse and fine components in the slurry, ensuring the independence and accuracy of each particle size measurement. A single instrument can detect 3 slurry flow channels with different properties, and each flow channel can achieve simultaneous measurement of 5 particle sizes and 1 concentration value. The product has a wealth of field experience, which can be combined with the actual working conditions of the site to carry out sampling plans and drainage back to the mine design, reduce mine blockage, and increase sampling representativeness; through the upgrading of core components, the reliability and maintainability of the instrument can be improved.
