Gilson Bulk Spinning Riffler scales up precision dividing and sample preparation for large bulk samples with greatly improved accuracy over traditional riffle splitters. Aggregates, coal, or ores with particle topsize of 2in (50.8mm) are quickly and accurately split to 1/8 or 1/4 fractions with less handling and risk of sample loss.
The unit works equally well for finer granular materials or powders with large volumes and samples that do not flow well through fixed-chute, gravity riffle splitters.
The high-power vibratory feeder enhances efficiency and improves sample flow. All contact parts are made of high-quality stainless steel for long service life and low contamination risk. The total hopper capacity is 1.8ft³ (51L). The feed rate through the 6.5in (165mm) wide hopper discharge is controlled by an adjustable sliding gate that opens from 0 to 4in (0 to 102mm) and by power settings of the variable-amplitude vibratory feeder. The adjustable angle of the vibratory feeder and feed trough assembly ensures a constant, controlled flow of material. Eight precise sample fractions are divided into stainless steel collection pans rotating at a constant 14rpm (12rpm at 50Hz) on the turntable.
A precision 1/2hp gear motor drives the rotary turntable, and the 0.32ft³ (9L) collection pans interlocked with overlapping edges to prevent loss of fines. Lifting bars in the pans are positioned for easy and convenient handling. Working components are mounted in a durable, painted steel frame.
