Gilson Bulk Spinning Riffler

Gilson Bulk Spinning Riffler: Precision Sampling for Large Volumes

Introducing the Gilson Bulk Spinning Riffler, engineered to revolutionize precision sample preparation for large-volume bulk materials. This advanced device delivers significantly improved accuracy over traditional riffle splitters, making it indispensable for industries handling aggregates, coal, or ores. Effectively process materials with a particle topsize up to 2in (50.8mm), achieving reliable 1/8 or 1/4 fractions with reduced handling and minimal risk of sample loss.

Beyond coarse materials, the Gilson Bulk Spinning Riffler excels with finer granular materials or powders, especially those with large volumes or those that tend to flow poorly in conventional, fixed-chute gravity riffle splitters. Its design overcomes common challenges, ensuring consistent and representative sub-samples.

At the core of its efficiency is a powerful vibratory feeder, designed to enhance sample flow and overall throughput. All components that come into contact with the sample are meticulously crafted from high-quality stainless steel, guaranteeing exceptional durability and a reduced risk of sample contamination, thus prolonging the unit's service life. The generous total hopper capacity of 1.8ft³ (51L) accommodates substantial input volumes. Material feed rate is precisely controlled via a sliding gate, offering adjustable openings from 0 to 4in (0 to 102mm), complemented by the variable-amplitude settings of the vibratory feeder. An adjustable angle for both the vibratory feeder and feed trough assembly ensures a constant, controlled, and optimized material flow into the dividing mechanism.

The heart of the riffler is its rotary turntable, driven by a precision 1/2hp gear motor, which rotates at a consistent 14rpm (12rpm at 50Hz). This turntable precisely divides the sample into eight distinct fractions, collected in robust 0.32ft³ (9L) stainless steel collection pans. These pans feature interlocked, overlapping edges to prevent any loss of fine particles, ensuring the integrity of each sub-sample. Strategically placed lifting bars in the pans facilitate easy and convenient handling. All working components are securely mounted within a durable, painted steel frame, built for stability and longevity in demanding environments.
