Apparatus and method for acquiring samples of mixed bulk materials in a flow

摘要

The present invention provides apparatus and method for sample acquisition from an active flow of mixed powder material being transferred from a blender. The apparatus includes a sleeve that is assembled co-axially to a discharge port of the blender and a number of sample collectors which each include a shaft with sample cavities and a tube that is rotatable around the shaft for exposing and covering the cavities. The sample collectors are alternately inserted through a bearing collar into the sleeve. The tubes are plugged at their respective outer ends to prevent accidental removal from the sleeve. The method includes inserting and opening each of the sample collectors in turn and removing the collected samples for analysis.
