Principles of operation
The Rotary Tube Divider (PD) is designed for representative dividing of bulk material.
Download Rotary Tube Divider brochure (PDF)General description
The drive unit rotates a dividing tube, where the material stream is constantly poured in a spherical pattern on the inside of the bottom cone. The slot opening(s) in the bottom cone extract(s) a quantity corresponding to its width and the rest passes into the reject outlet.
The dividing ratio is adjusted by setting the damper in various positions and thereby decrease/increase the opening in the bottom cone. The division ratio is steplessly adjusted between 1:8 and 1:89 – dependent of PD model and particle size.
The Divider essentially consists of the following units:
- Drive unit
- Dividing tube
- Top cone
- Bottom cone
