Overview

The development and quality assurance of RBG professional aerosol generators, as well as the calibration of particulate matter measurement equipment, require low concentration solid particulate matter aerosols generated from powders for many applications.

Product Details

Many applications of research and quality assurance, as well as calibration of particle measurement equipment, require low concentration solid particle aerosols generated from powders.

For over 25 years, RBG systems have been widely used around the world to reliably disperse non stick powders with a size range of<100 µ m and a fine fraction of<100 nm, such as mineral dust, active pharmaceutical ingredients, pollen, etc., achieving great success. Single solid materials such as blackboard chalk ash can diffuse finely and have high feeding consistency.

The advantage of this feeding and diffusion system is that in the RBG system, by quickly and easily replacing the solid material tank, a mass flow rate of about 40 mg/h to about 800 g/h can be dispersed with high feeding consistency.

RBG basic can work with nitrogen as a carrier gas.

start

Gradually inject the dispersed powder into the cylindrical solid material tank and compact it. Lucerne University has determined that the compacted density of solid material tanks has high repeatability with a deviation of 3.4%. Insert the injected solid material tank into the RBG diffusion head. Then uniformly compress the powder at the injection height and deliver it to the rotating brush at a precisely controlled feeding speed. Adjustable airflow flows at high speed through tightly interwoven precision brushes, separating particles through the brushes. The diffusion head assembly includes a diffusion holder, diffusion cover, precision brush, and solid material tank.

feeding

Feeding is carried out through precise control of the feeding speed by the feeding piston. It is easy to reproduce and determine the required mass flow rate: based on the cross-sectional area of the solid material tank, the precisely adjustable feeding piston feeding rate, and the easily determined powder compaction density inside the tank.

32 mm	88 g	800 mg/h	8 g/h	80 g/h	800 g/h

diffusion

By accurately brushing the powder separated from the tank, it almost diffuses into the component particles in the diffusion head under the action of high-speed diffusion airflow (see Figure 2). Adjust the diffusion airflow by manually setting the pre pressure.

Four different diffusion covers can be used to achieve ideal diffusion.
