Spinning Rifflers virtually eliminates operator errors common with other types of sample dividing. Representative sampling by spinning riffler is the method of choice for accuracy and repeatability of the highest order when sampling dry, granular materials, and powders. The Spinning Riffler and larger-scale Accu-Max Spinning Riffler each offer exceptional performance in reducing dry bulk materials.
Gilson Spinning Riffler is designed for finer granular materials and powders and features a touchscreen controller for complete regulation of vibration and speed settings.
Accu-Max Spinning Riffler provides precision dividing and sample preparation of large bulk samples by splitting samples of aggregate, ore, coal, and other materials in volumes of up to 1.8ft³ (51L). Particle top sizes up to 2in (50.8mm) are quickly divided into 1/8 or 1/4 fractions.
Precision Splitters quickly divide granular materials and fine powders to produce representative samples for laboratory analysis. These single stage riffle-type splitters feature a gate-controlled hopper and precision fixed-width chutes for increased accuracy. Samples are divided in half with each pass and are collected in receptacles under the chutes.
Construction is all heavy-gauge type 304 stainless steel for corrosion resistance, increased service life, and reduction of sample contamination. An easy-flip gate hopper control enables samples to be loaded completely and evenly distributed before opening. Side panels control dust to reduce the loss of fines, and units disassemble quickly for cleaning.
SP-300 Precision Splitter has sixteen chutes with 0.5in (12.7mm) chute width opening, and the chute angle is 45°. Hopper capacity of 132in³ (2.2L). The maximum recommended particle size 0.2in (5mm).
SP-302 Precision Splitter has sixteen chutes with 0.25in (6.4mm) chute width opening, and the chute angle is 45°. Hopper capacity of 61in³ (1L). The maximum recommended particle size is 0.09in (2.2mm).
SP-304 Precision Splitter has thirty chutes with 0.125in (3.2mm) chute width opening, and the chute angle is 45°. Hopper capacity of 61in³ (1L). The maximum recommended particle size is 0.04in (1mm).
SP-306 Precision Splitter has thirty chutes with 0.06in (1.6mm) chute width opening, and the chute angle is 60°. Hopper capacity of 8.8in³ (0.14L). The maximum recommended particle size is 0.02in (0.6mm).
