Description Gravity Seperator
A gravity separator precisely and efficiently separates grains and seeds based on the specific weight of the kernels. The machine divides the raw material into two fractions and is capable of separating particles with only a slight difference in bulk density. Gravity separators are used worldwide in installations for the production of seed, flour, pearled grain and similar products, effectively removing impurities that other cleaning methods cannot distinguish.
Applications of the Gravity Separator
- Grains – wheat, barley, rye, oats, maize: separating full, heavy kernels from light or damaged kernels
- Pulses – peas, beans, soy: quality sorting
- Seeds – grass seed, rapeseed, beet seed, vegetable seeds: removing light or damaged seeds
- Rice – separating filled and empty kernels
- Coffee and cocoa – quality separation of beans
- Nuts – hazelnuts, walnuts, peanuts: removing empty or light nuts
- Plastic granulate – density sorting in recycling
- Minerals and sand – separation of materials with different densities
- Chemical products – granulate, pellets
How the Gravity Separator works
The product passes over a slightly inclined, vibrating perforated deck. The heavier material maintains contact with the perforated deck and, due to the vibrating motion, is conveyed towards the higher side of the machine. Lighter material rests on top of the layer, has no contact with the vibrating motion, and floats across the air deck towards the lower side. This operating principle is illustrated in the animation. The inclination angle, vibration speed and air volume can all be adjusted.
In the animation, the heavy particles are shown in yellow, the air in blue and the light particles in purple.

Remarks
- Dimensions and weights are stated without the fan.
- apacities apply to wheat with a bulk density of 750 kg/m³.
- roduct must be pre-cleaned using sieves and air.
- The volume of aspirated air is greater for heavier materials (e.g. pulses) and lower for lighter materials (e.g.
- unflowers).
- Machine capacities are indicative and depend on the type, quality, moisture content and impurity level of
- he processed product.
- The extracted air must be cleaned using a cyclone separator or filter.
