Introduction to Rotary Sample Divider, Rotary Splitter and Spinning Riffler


Rotary sample divider is a type of laboratory sample splitter or sample divider. HMK-2001 Rotary Sample Splitter uses frequency controlled rotary motor and vibration-controlled device to optimize the sample dividing. It is much more superior to the traditional manual riffle sample splitter and has been widely used in lab powder analysis applications especially with particle size analyzers. HMK-2001 Rotary sample divider has become the most frequently used spinning rifflers representative sampling instrument in nearly all industries.

HMK-2001 rotary sample divider is a sample splitting instrument before furthter analysis of dry powder in the laboratory. HMK-2001 spinning riffler automatically, quickly and effectively divides the samples to be analyzed into 6 or 8 equal shares; each share has the representation of the original sample.

  • Rotating sample divider consists of the following major parts: control panel, vibration feeder, sample receiver and sample cleaning device, etc. Control panel consists of vibration feeder panel and receiver sample panel. Vibration feeder panel consists of vibration feeder power switch and the vibrating feeder amplitude speed control knob. Sample receiver panel consists of power switch and high, medium and low key of rotation speed as well as stepless adjustable plus and minus key. Vibration feeder consists of vibrating base and sample pool. Sample receiver consists of composite funnel, tube clip, and six or eight tubes. The sample cleaning device consists of holder and cleaning brush.
