"BPSM-I online particle size analyzer" consists of eight parts: slurry steady flow box, instrument control box, electronic touch screen, valve box, air purification device, measuring head, calibration sampler and rack. The core part of the instrument is a nationally-accepted measuring head with high technical content; the second is the instrument control box, which is equipped with a PLC programmable controller and the corresponding unit module, which is the command center of the instrument; the electronic touch screen is Input, output, and human-machine dialog operations.
"BPSM-I online particle size analyzer" solves the following key technologies: ensuring the development of measuring probe structure with high precision and high stability; solving the problem of hard and difficult processing of dynamic and static measuring contacts; ensuring instrument measurement Design, selection and procurement of displacement sensors with precision and sensitivity; software mathematical processing methods for measuring displacement signals; and sampling devices for measuring representative samples.
"BPSM-I online particle size analyzer" is a direct measurement type slurry particle size measuring instrument. The zero-correction technology of the instrument automatically eliminates the drift of the instrument and the influence of the wear of the measuring contact; the change of the viscosity, temperature and concentration of the slurry has no effect on the normal measurement of the instrument; the measurement of the instrument by the bubble and the flake mineral is not It will cause any interference; and, without degassing, demagnetization or dilution; it completely overcomes the measurement environment and external factors to bring errors to the measurement. Achieve absolute accuracy: ? Accuracy 1 - 2%; Particle size range: 600μm ~ 31μm? (30 ~ 500 mesh); ? Measurement of the grain size: ? In the particle size measurement range, the user can optionally calibrate 2 measurement particles for display and output level. It has reached the advanced level of international similar instruments.
According to the incomplete statistics of the application of Yongping Copper Mine, the annual grinding efficiency is 6%, and after deducting the production cost, the annual economic benefit can reach 8 million yuan. At present, it has signed a contract with the Baotou Iron and Steel Group Concentrator to repair the “PSI-200 Particle Size Analyzer†imported from Finland using domestic measuring heads; the prospect of promotion and application is good.
The development of BPSM-I online particle size analyzer is an automatic detection device for key parameters in the continuous production process of mineral processing. It can be applied in industries such as nonferrous metals, black, cement, chemical, gold, etc. It is the fifteen research project approved by the Ministry of Science and Technology. A sub-item of the project "Research on Mineral Processing Process Monitoring Technology and Automatic Control System".
