HY-RDAG550A dust generator

Application fields of HY-RDAG550A dust generator
Research experiments: used for aerosol science, dust prevention and control, occupational health research, simulating industrial and mining dust production sites, studying the physical and chemical properties, diffusion laws, etc. of dust.
Industrial testing: Calibrate particle measurement equipment (such as dust particle counters and dust detectors), test the filtration efficiency of filters, and evaluate the performance of protective equipment such as masks and filter materials.
Environmental monitoring: Simulate indoor or outdoor dust pollution environments, evaluate the effectiveness of air purification equipment, and study the sources and migration patterns of atmospheric particulate matter.
◆ Public health: In respiratory exposure testing and inhalation toxicity research, specific particle sizes and concentrations of dust are generated to simulate the human respiratory environment and evaluate the impact of dust on human health.

Working principle of HY-RDAG550A dust generator
The HY-RDAG550A dust aerosol generator adopts the principle of rotating electric brushes, and controls the precision slide table through a high-performance controller combined with self-developed algorithms to achieve precise feeding and sample feeding. The rotating electric brush pushes the sample to the shearing port, and the high-speed airflow through the slit cuts and disperses the powder sample, forming a stable dust aerosol.
Performance characteristics
Touch screen control: The system's operating parameters are detected and controlled through an industrial touch screen, with a friendly human-machine interaction interface，Easy to operate.
Intelligent detection: It has a gas source pressure detection function. When insufficient gas source pressure is detected, the system will not be able to start or stop working immediately to avoid damaging the instrument.
◆ Operation interface: The interface displays real-time parameters such as gas source pressure, gas flow rate, powder mass flow rate, theoretical concentration, remaining working time, feed rate, brush speed, etc., making the operation status of the instrument clear at a glance.
◆ Precision feed sample feeding: Sample feeding is carried out through servo motors and precision slide tables, with adjustable feed speed.
Gas flow regulation: It has gas flow regulation and flow detection alarm functions.
Theoretical aerosol concentration display: The system automatically calculates and displays the theoretical aerosol mass concentration in real-time based on the detected gas flow rate and powder mass flow rate.
