The complete set of production operations usually equipped in the grain depot, because of its relatively large output, the raw grains on the market contain a lot of impurities, so when choosing this sieve type, choose a sieve with a sieve width of 1.8m, because the sieve type with a width of 1.8m is Double feed inlets can make full use of the effective width of the screen surface for sieving, while the screen type of 1.5m wide screen surface is single feed inlet, the material layer is concentrated in the middle of the screen surface, and the screen surface itself is narrow. On this issue, its flow cannot produce the requested.

Grain cleaning and screening In addition to corn, it can also clean sunflowers, soybeans, white melon seeds, corn, wheat, rapeseed, rice and other food crops. It has the multi-purpose performance of one machine, such as grain cleaning, sieving, grading, etc. It has the characteristics that other grain cleaning machines do not have, and its performance is stable.

The role of the grain cleaning sieve is more than that. After the material is put on the machine sieve surface, because of the reverse wind acting on the fish scale sieve surface, the material has two completely different movement directions due to the difference in specific gravity, and the specific gravity moves forward. Entering the next cleaning process, the material with light specific gravity (mold seeds) goes backwards and is pushed out of the miscellaneous opening by the internal screw auger. Although the efficiency of removing impurities is high, it can better meet the production requirements. The sieve type has a better cleaning effect on small impurities, and the sieve surface is not easy to be blocked because of the self-cleaning balls. However, the sieve is very sensitive to fibrous impurities such as ropes and grain whiskers. If there are too many such impurities and the cleaning is not timely, it will stick to the large miscellaneous screen surface, reduce the effective screening area, and some grains will flow to the large miscellaneous outlet, which will affect the output of the equipment and the cleaning effect, so it should be cleaned up in time Work.
