About This Product
Powder flow testers measure how a bulk powder behaves under load, which is needed when designing hoppers, chutes and silos so that the powder does not form an arch or a rat-hole and stop flowing. The results, such as flow index and hopper half angle, help to choose outlet sizes and wall angles. The wall friction test shows how the powder slides against the surface of the container material. School Lab Equipment India supplies the Powder Flow Tester across India and can export it to Brazil, Tunisia, Antigua and Barbuda, Nicaragua, Botswana and Ecuador.
