Rotating Tube Divider

A faultless and comparable analysis is closely linked to accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results. Rotary tube dividers ensure the representativeness of a sample and thus the reproducibility of the analysis.

The Rotating Tube Divider is the prerequisite for dust-free division and volume reduction of larger bulk samples. It is suitable for powdered or granular bulk materials. The slot width adjusts the ratio of the fractions and therefore the amount of sample.

FUNCTIONAL 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.
