Rotating Tube Divider PK 1000
Retsch PK 1000 rotary tube dividers are the prerequisite for the representative, dust-free dividing and reduction of larger samples of bulk material. For quality-conscious manufactures, processors and testers, exact sample dividing must be as important as error-free analysis. Only an exact analysis sample gained without the use of manual methods can guarantee unfalsified test results.
Application Examples
cement clinker, chemicals, coffee, construction materials, fertilizers, fillers, flours, grains, metals powders, minerals, nuts, sand, seeds, soils, washing powder, ...

Function Principle
The material to be divided passes through the feed hopper via the chute of the vibratory feeder into the rotating tube divider. The total material stream is distributed evenly at a constant speed (50 min-1) over the pitch circumference of the lower cone by the tube rotating within the upper cone. The interchangeable lower cones have one, two or three continuously adjustable sample slots. In the course of each rotation a separated quantity corresponding to the width of the slot is deposited in the sample collecting vessel. The rest passes into the reject container.
