Stable performance of grain cleaning and screening in the grain depot, thorough screening of grains

The complete set of production operations usually equipped in grain depots, due to their relatively large output and high impurities in the raw grains on the market, should choose a sieve with a screen width of 1.8m when selecting this type of sieve. This is because the 1.8m wide sieve type has dual feed ports and can fully utilize the effective width of the screen surface for screening, while the 1.5m wide sieve type has a single feed port and the material layer is concentrated in the middle of the screen surface. The narrow screen surface itself, coupled with this problem, cannot meet the production requirements for flow rate. Our company specializes in producing grain conveyors

In addition to corn, the grain cleaning screen can also clean various grain crops such as sunflowers, soybeans, sunflower seeds, corn, wheat, rapeseed, rice, etc. It has multiple functions such as grain cleaning, seed screening, and grading, and has characteristics that other grain cleaning machines do not have. It has stable performance and thorough grain screening.

The role of the grain cleaning screen is not limited to this. After the material reaches the machine screen surface, the reverse wind acting on the fish scale screen surface causes the material to move in two completely different directions due to its different densities. The heavier material moves forward into the next cleaning process, while the lighter material (mold seeds) moves backward and is pushed out of the impurity outlet by the internal spiral agitator.

Although the grain cleaning sieve has a high efficiency in removing impurities and can better meet production requirements, this sieve type has a good effect on cleaning small impurities. The sieve surface is not easily clogged because it has self-cleaning balls. But the sieve is sensitive to fibrous impurities such as ropes and grain whiskers. If there are too many such impurities and they are not cleaned in a timely manner, they will stick to the surface of the large impurities sieve, reducing the effective screening area and causing some grain particles to flow to the large impurities outlet, affecting the equipment output and cleaning effect. Therefore, the grain conveyor should be cleaned in a timely manner.
