Typical Application
In one plant of Benxi Iron and Steel Group, the particle size of ore crystals is small. In the third stage of grinding, the particle size of 500 mesh (- 25 microns) varies from 70% to 95% and the mass concentration varies from 10% to 60%. Also, the source of raw ore on site is frequently replaced, and the variation range of its concentration and particle size is close to or even beyond the detection range of the analyzer. By upgrading the ultrasonic measurement system and algorithm model, DF-PSM can effectively track and detect ultra-fine particle process pulp. The problem of difficult detection for original particle size analyzer's three-stage-500 mesh target particle size and inadaptability to the frequent changes in the field process was solved. After the calibration and variation for nearly 2 months of the improved ultrasonic particle size analyzer, the particle size detection accuracy of -500 mesh samples has reached 0.99%, which meets the site requirements and can guide site production.
