Suction type gravity destoner are mainly used in food processing plants, separate side by side stone isobaric than grain impurities from wheat, rice, used to separate some other grains in the complex.
It is the use of grain weight and the proportion of the stone and the suspension rate of different characteristics, through the grain flow through the flow of particles in the gap between the flow of grain and stone grading. Side by side stone complex in the lower layer, the directional inclined reciprocating motion to slate under, towards the end of stone movement, floating in the upper layers of the grain under the action of gravity, scroll to the end, thus the side by side stone from grain separated.
The twisting joint of the reciprocating swinging mechanism of the machine adopts a special rubber bearing. Rubber bearings, durable, vibration absorption. The machine is stable and reliable, strong and reliable, small vibration, small noise. In the upper stone suction wind, no dust outside, the use of a larger wind and air suction hood, the negative pressure on the slab surface is similar to the wind, in the past the wind uniform, easy to adjust the wind, and a large range. Therefore, the destoner yield fluctuation in a certain range, can achieve a better effect to stone. The tilting angle of the stone slab can be adjusted within the range of 10-14, so it can be used to remove the stone in different kinds of grain.
