Working principle of chamber:
Centrifugal fan is the main source of dust movement, the high-speed operation of the fan so that dust into the fan due to the centrifugal force of the role of fan blades into the dust pipe dust. The wind speed of the pipeline is usually more than 7.5m / s (too low wind speed will make the dust precipitate in the pipeline will cause the test tube can not work). The dust line was sprayed from above into the test chamber and passed through the sample at a rate of> 2 m / s. Sand and dust chamber As the lower part of the working box for the funnel, it can precipitate down the dust into the lower part of the 72 × 50um filter. Through the vibrating motor vibration, less than the diameter of the filter hole in the dust and centrifugal fan sucked so back and forth.
