TQSX suction type gravity destoner is mainly applicable for grain processing factories to separate the heavy impurities such as stone, clods and so on from paddy, rice or wheat, etc.. The destoner exploits the property difference in the weight and suspension velocity of grain and stone to grade them. It uses the difference of specific gravity and suspending speed between grains and stones, and by means of air stream passing up through space of grain kernels, separates stones from grains. The heavy impurities such as stones having the same size and shame with grain kernels are in the lower layer and move to the stone outlet by means of directional, slope and reciprocating movement of stoning sieve plate, while grains floating in the upper layer roll under self gravity to discharge outlet, so as to separate from grains the stones having the same size and shame with grain kernels. It also can be used to separate heavy impurities from other grains like soybean, rapeseed, peanut, etc. in grain processing. The stones are dropped to the ground and the grain flow in the air, and then the grain rolls into the discharge pipe because of weight.
1. High stone-removing efficiency; with shutter sieve, it is more suitable for some grain processing plants where there are more stones content in raw grain.
2. The inclination of shutter sieve varies from 100 to 140 depending on the different feedstock to attain the best processing effect.
3. With external fan, full sealed machine, and no dust outside machine, thereby gaining the end of environmental protection.
4. Adopt reciprocating mechanism with rubber bearing, less vibrating, low noise.
5. Adopt self-aligning bearing with looseness prevention device so as to make mechanical property more steady.
