Abstract
The Slotted Cone Splitter
F. J. Flanagan, R. C. Kellagher (2), W. L. Smith (3)
ABSTRACT
A laboratory sample splitter was designed in the form of a 60° cone over whose surface the entire sample passes. The split is captured by falling through pie-shaped slots on the surface of the cone. The splitter sampled an average of 13.5 percent of a crushed quartz monzonite, of which 80 percent passes a 140-mesh sieve.
The amount of sample captured is dependent on the particle size of the material sampled. A line of regression of the percent captured on size and confidence limits for the estimate of the means of the amount split are shown. Some qualities desirable in a splitter are enumerated and the conformity of several splitters to these criteria is discussed.
