Grain screening machine is a grain processing machine for grain cleaning, cleaning and grading. Various types of grain cleaning use different working principles to separate grain particles from impurities. It is a kind of grain screening equipment. Filter out the impurities inside, so that the grain can be better processed and used.
The equipment combines the functions of air separation and impurity removal, specific gravity classification, volume classification and other functions into one. The finished grain has good purity and high quality, reduces labor, increases production, saves energy and reduces consumption. The comprehensive performance is better than similar products, and the cleaning speed is fast. , high efficiency, suitable for grain seed purchase and processing households, etc., scope of application: this machine has a good cleaning effect on beans, corn and other granular materials. It can remove more than 90% of light particles such as seeds, buds, insects, mildew, smut, etc. The feeding method can be selected from hoist, auger, and belt conveyor, which is flexible and convenient.
The machine is equipped with a feeding hoist, an impurity removal fan and a spiral dust removal system, which can discharge light dust and other impurities in a concentrated manner. It has a compact structure, convenient movement, obvious dust and impurity removal efficiency, low energy consumption, and easy and reliable use. Mesh sieve The net can be exchanged arbitrarily according to user requirements.
The bulk material plate of the bulk material box of the grain screening machine completely disperses the material, and the three-layer diffuser plate falls layer by layer to make the material gradually thinner and vibrate the mixed dust. The dust is sucked out to complete the secondary pre-dust removal process; the material continues to descend and enters the sieve plate surface of the specific gravity separation table, where a small amount of residual dust is shaken up again, and the other blade of the double-leaf fan passes through the suction port and the suction cover to remove the dust on the sieve surface Suction out to complete the second dust removal process.
The reciprocating movement of the separation table, under the action of the airflow of the main fan, makes the incoming wool grains in a suspended state and produces a diffusion movement; due to the application of the principle of specific gravity, various substances mixed in the material are in a distinct upper and lower layer according to their specific gravity and shape. distribution, under the action of the inclination angle of the screen surface and the viscosity of the reverse air flow, the grain and impurities separated by the screen surface will undergo reverse differential motion to complete the secondary cleaning and separation process; Collected and discharged, the grain moves forward along the sieve surface under gravity throwing, and enters the sieve surface of the grading vibrating screen for grading and screening. The coarse impurities mixed in the grain remain on the sieve surface and are discharged out of the machine through the coarse miscellaneous outlet.
