Since aeration is arguably the single most important parameter influencing the flow properties of a powder, accurate determination of its effects at all flow rates is critically important
A new version of the Aeration Control Module for Freeman Technology's FT4 universal powder tester extends the operating range down to an extremely low air velocity of 0.02 mm/s.
The high degree of control at very low flow rates that this module now delivers is essential for characterising powders that are sensitive to the addition of a very small quantity of air, such as toners and some powder coatings.
The Aeration Control Unit allows fine control of air flow through a powder under test, enabling fully automated measurement of flow properties as a function of increasing levels of aeration.
The FT4 can be used to determine the flow properties specification needed to optimise production and achieve the required product quality.
On a day-to-day basis it has applications in verifying that powder flow properties meet the necessary specifications, for predictable and consistent processing performance.
