Product Details

OMEC At-lineOnline granularity detection and control systemIt is a new generation online particle size analysis instrument developed by Zhuhai Ouaike Instrument Co., Ltd. based on its mature and high-performance particle size analysis optical platform, which can be customized according to the customer's production line situation. The system consists of an innovative representative sampling device, a representative sample reduction device with precise and controllable sample addition, a high-performance dry light scattering measurement device, a secondary sampling device to avoid material stacking, and a display and control assembly, and is compatible with offline manual sample injection verification.

The system features a secondary sampling and feeding design, a secondary material recycling design, and a test window wind knife anti pollution self-cleaning design, which truly enables the online testing application of laser particle size analyzer to have the ability of fast data response, long maintenance free cycle, no need for manual duty, remote or centralized control, and data display. Combining the system to provide personalized data analysis and intelligent control adaptation functions for production line abnormal alarms and iterative upgrades, allowing system users to access them through the system panel, remote computer interface, mobile mini program, or user interfaceDCSReal time viewing of test results and trends through various channels such as the system, and quick guidance for central control machine adjustment.

OMEC At-lineOnline granularity detection and control systemIt can be customized according to production line and quality control requirements, with high degree of intelligent automation, long maintenance free cycle, strong real-time testing performance. The system also has the advantages of wide detection range, good repeatability, high resolution, and consistency with offline granularity testing results.

Working Principle:

Particle samples are dispersed in a gas at an appropriate concentration. When a beam of parallel light encounters obstacle particles during propagation, the light wave will undergo scattering (diffraction) deflection, and the deflection angle is related to the size of the particles. The scattering (diffraction) phenomenon can be observed through “MieThe scattering theory is used to describe it. Generally speaking, the larger the particle size, the smaller the angle of light wave deflection; The smaller the particle size, the greater the angle of light wave deflection. The laser particle size analyzer utilizes this phenomenon to measure the distribution of scattered light energy and invert the particle size distribution of the measured particles.

Dry online laser particle size testing, detecting the particle size of the production line every few minutes, displaying real-time particle size distribution data, and achieving closed-loop automatic particle size control through computer monitoring combined with production line parameter adjustment.
