NSD are remarkable all new complete, simple and compact cleaner separator with some interesting features:

• Rubber balls for screen cleaning with no adjustment or maintenance.
  
• Final aspiration
  - accurate with a high air lifting chimney,
  - balanced with one aspiration on one grain flow collected from screen boxes,
  - maintaining efficiency with a double grain cascade allowing no fouling or unwanted air entry.
• Large screen area with standard split screens, allowing easy screen exchange, even after a long run, with a simple release mechanism.

NSD série 1, with one screen box, throughput 25 to 35 TPH.
NSD série 2, with two identical screen boxes, throughput 50 à 70 TPH.

The latest in the range, NSD 3 allows output of 100 TPH

For commercial or standard cleaning,
all screens are used:
- upper screen (scalping) removes large impurities
- lower screen (screening) removes small impurities.

For pre-cleaning, or when cleaning rapeseed for example, when mere scalping is enough, the lower screen is not generally performing a useful function,
only the upper screen is actually needed.
The modular option (outlets and bottom) allows
all screens to be used for scalping
thus doubling the effective screen area,
thus increasing throughput.

On the other hand, when grading malting barley,
when only the lower screens are needed for screening with slots 2.50x20, a simple outlets exchange allows
all screens to be used for screening
thus doubling the effective screen area,
thus increasing grading efficiency.
