Abstract

A method and apparatus for on-line analysis of a coal sample. Four radial arms (16) extend from the output shaft (28) of an indexing motor (14). Sample cups (12) at the ends of the arms are indexed along a circular path past a filling station (18) where the cup is filled with pulverized coal, an analyzing station (20) where various chemical analyses are performed on the coal sample, a dumping station station (22) where the residue of the coal sample is dumped for disposal, and a cleaning station (24) where the sample cup is cleaned in preparation for another analysis cycle.
