ABSTRACT:
A method and apparatus are provided for cross-stream sampling of bulk material on a belt conveyor. The cross-stream sampling apparatus disclosed includes sample taking elements movable across the conveyor for removing a cross-stream increment of bulk material and contour elements for modulating the normal troughing of the conveyor belt and supporting and conforming the conveyor belt to the operative course of the sample taking elements as it moves across the conveyor belt. One form of the method includes segregating a cross-stream sample increment of the bulk material and sweeping the segregated increment from the conveyor belt and supporting and conforming the conveyor belt to the operative course of segregation and sweeping.
