Equipment and complete systems for representative sampling of granular bulk material
DD – Disc Divider
- Dosing and representative dividing of bulk material
- Easy and stepless adjustable division ratio
- Divides material with particle size up to ø20 mm
- The divider is a simple and economical solution
- Compatible with most international sampling standards for bulk material
- Made from stainless steel AISI 304
Principles of operation
The Disc Divider (DD) is used for dosing and dividing of bulk material. A representative sample is ensured by a continuous automatic division.
General description
The material is fed to the Disc Divider through the top section, where the material is scraped off the upper disc down to the lower disc. Here, the material is scraped down to the bottom section, where the slot opening(s) extract(s) a quantity corresponding to its width and the rest passes into the reject outlet. The division ratio is stepless adjusted between 1:9 and 1:56 –dependent of DD model and particle size.
The Disc Divider is manufactured of stainless steel and essentially consists of the following units:
- Top section: The upper disc and two scrapers.
- Middle section: Lower disc, drive unit and the rotor which is connected to the above mentioned scrapers.
- Bottom section: Cone with one or more adjustable sample outlet(s) and reject outlet.
- Inspection hatches for easy access.
