RETSCH: Rotary Tube Divider
August 15, 2005
With Retsch's new Rotary Tube Divider PK 1000, one or more representative laboratory samples can be extracted conveniently from granular or powdered substances with a feed size of up to 10 mm. Typical applications include fertilizers, grains or coffee, however any free-flowing, pourable bulk material up to 30 liters can be handled. The representative samples provided by the instrument assure reliable, meaningful analysis results. Introduced to the divider through a vibratory feeder, the product passes into the cone where a rotary tube rotates at a constant speed of 50 rpm. With each rotation, a portion of the sample is deposited by the rotary tube through the slot into the sample collector. The dividing ratio and the volume of the extracted sample are determined by the width of the slot, which can be adjusted continuously from 0-73 mm. The remaining sample is collected in a reject container. With a choice of three different lower cones with 1, 2 or 3 outlets, the PK 1000 can be ideally adapted to individual sampling tasks. All parts in contact with the material are made of stainless steel.
