Abstract

Pick-up velocity is a threshold value that is taken into account while designing a powder hydraulic or pneumatic conveying system. In this work, a new and simple procedure to measure and predict the pick-up velocity is presented by using a Rheometer. Using a Rheometer, the moment the particles are picked up from a layer is measured by the viscosity change of the upper fluid while the rotation speed increases. By measuring the viscosity change while reducing the rotation speed, it becomes possible to define non-settling particles. Comparing to other works shows, that the new procedure can predict the pick-up velocity and to define non-settling particles well.
