Device for measuring the angular distribution of flow speeds and / or of the trajectories of the particles to a distributor centrifugal of solid particles has apply

摘要

Uses constant stroboscopic or instantaneous flash lighting and camera synchronized with the angular position of a disk (1). The flash or stroboscopic trigger is synchronized with the angular position of the disk. A back screen assures a dark rear plane background for the scene. Device for measuring the angular spread distribution of solid particles such as fertilizer around each disk (1) of a centrifuge distributor. The distributor is of the type having a hopper from which the particles to be spread fall under gravity onto rotating bladed disks which spread the particles. The device has a measuring system including a camera which is placed in a vertical or oblique position framing the spreading disk.
