Sieve Separator with Pneumatic Channel SSW+KPO

The Sieve Separator is designed for separating and removing impurities smaller and bigger as well as lighter than the grain being cleaned by means of pneumatic channel.

Capacity for wheat and rye with humidity up to 15% and contamination 2÷3% (normal). For grain with higher humidity and higher contamination, capacity is considerably lower (i.e. when humidity exceeded 22% - max 50% capacity).

For corn capacity is lower – about 90%.

For barley capacity is lower – about 80%.


Basic elements of the separator are:

  • body with sieve decks – upper and lower; the sieve decks are protected with blocking beams;
  • dimensions of the sieve:

- width= 995 mm, length=1000 mm for SSW100/100,
- width= 995 mm, length=1500 mm for SSW100/150,
- width= 995 mm, length=2000 mm for SSW100/200,
- width= 1495 mm, length=2000 mm for SSW150/200,

Sieve deck as a standard consists of one or two sieves 750 mm or 1000 mm long. If there is a limited space for sieve disassembly on site, a different division can be made on request.

Elements of the body are also:

  • product outlet,
  • outlets of impurities,

- bigger than grain,
- smaller than grain,

  • product inlet,
  • supporting frame with shock absorbers
  • drive assembly forcing the vibratory movement of the machine,
  • supporting construction with inlet of the product,
  • inlet connection.

Pneumatic channel comprise internal adjustable and air throttling valve allowing setting of optimal cleaning.

Operation principle

Grain for cleaning flows into the machine with inlet connection onto the upper deck of sieves. Passing through an inlet box, it is distributed onto the whole width of the sieve.
The upper deck separates the „big" impurities, like: strings, ears, straws, stones, pieces of broken glass, wood, etc. they are taken out from the machine by upper side outlet.
The grain with smaller impurities flows onto the lower deck of sieves, where small impurities like: small and broken grains, weed seeds and sand are separated. The impurities are taken out by lower side outlet outside the machine. Overtails from lower deck are cleaned grains which flow to the central outlet of the separator.

Grain flows into pneumatic channel and falls gravitationally to outlet. Simultaneously impurities lighter than grain are separated and directed to aspiration installation.
