Gilson's Accu-Max Spinning Riffler scales up precision dividing and sample preparation for large bulk samples. Aggregates, coal, or ores with particle topsize to 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 starting volumes. Samples that do not flow well through fixed-chute gravity splitters process more efficiently through the powerful vibratory feeder of the Accu-Max, enhancing accuracy and efficiency, and improving test results. All contact parts are of quality stainless steel for long service life and low contamination.
Total capacity of the hopper is 1.8ft³ (51L). Feed rate through the 6.5in (165mm) wide hopper discharge is controlled by a sliding gate that adjusts for openings from 0—4in (0—102mm), and by power settings of the variableamplitude vibratory feeder. Adjustable angle of the vibratory feeder and feed trough assembly assures a constant, controlled flow of material. Eight precise sample fractions are divided into special stainless steel collection pans rotating at a constant 14rpm (12rpm at 50Hz) on the turntable. A precision 1/3hp gearmotor assembly drives the turntable, and the 0.32ft³ (9L) collection pans lock together with unique overlapping cutting 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. Eight Collection Pans for 1/8 fractions are included. Extras are available as SPA- 30. Double-sized pans for 1/4 fractions are also available as SPA-31.
