For larger foundries, one of the advantages of segregating core sand streams from molding sand streams is that the two types of sands are better suited for different markets.
If you must sample within the foundry, it is best to "cut" a moving sand stream periodically and combine these samples, and then reduce the sample's size by using a sand splitter.
