In the beneficiation process, particle size is a very important indicator in the grinding and classification process, which directly affects the processing capacity, energy consumption, steel consumption and the processing effect of the subsequent process flow. The application of Ultrasonic Online Particle Size Analyzer (DF-PSM) better solves the problem of real-time detection of process pulp particle size, and ensures that the production process is in the best working state under the premise of qualified particle size, that is, the grinding and classification quality is the best and the output is the largest. At the same time, the labor intensity of workers can be reduced and the problem of poor control caused by the lag of manual testing can be solved. In recent years, with the continuous improvement of the grinding and classification process, the demand for ultra-fine particle detection has risen sharply, while no better solution had been carried out due to the limitations of the original technology.
DF-PSM, which is independently developed by DFMC, is an online slurry particle size detection instrument. The product optimizes and upgrades the ultrasonic signal acquisition unit. Based on re-establishing the auxiliary parameter setting standard through mathematical modeling, combined with statistical metrology method to determine reasonable ultrasonic frequency range for particle size detection, and extensive experiments try and continuously improve the work of the data regression algorithm, the technical problem was eventually completely solved. And this filling the technical gap of online particle size detection in the field of ultra-fine particles in China. DF-PSM has been successfully applied in one plant of Benxi Iron and Steel Group , which has been unanimously recognized and praised by customer.
