Abstract
Apparatus for sampling material being conveyed on a primary conveyor comprises a diverter arranged to divert material onto a sampling conveyor running alongside the primary conveyor where it can be weighed by a weightometer and elevated to a discharge point before falling into a falling-stream sample cutter. Material is then returned to the primary conveyor at by a return conveyor. Options include the use of an impact conveyor between the diverter and the sampling conveyor, and the configuration of the sampling conveyor with a wider belt running at a slower speed to improve accuracy.
