Riffle Boxes

Riffle boxes ( sample splitters) are an inexpensive method of splitting bulk materials into representative samples. The most important factor in selecting a riffle splitter is to be sure that chute widths are sufficiently wide enough to prevent plugging or bridging of materials. The number of chutes must be sufficient to assure reasonable sampling accuracy. These riffle boxes are of heavy gauge sheet metal and have been designed for the rapid separation of bulk materials into two representative samples. Ruggedly constructed for long life, and with particular attention to the reinforcement of the partitions to maintain the accuracy of the slot dimensions. Each riffle is supplied with three metal collecting pans, two of which fit below the riffle box whilst in use.
