Corn and grain screening technology is affected by the following factors: raw material factor, equipment factor and operation factor.

First, corn kernels uniformity, moisture and impurities variety and quantity can directly affect screening effect. Second, the geometry factor and the movement parameter of the sifter can also affect screening technology. Besides, the operation factor, such as flow control, feeding mechanism adjustment, air volume adjustment and sifter cleaning, can decides the effect of the corn and grain screening technology.

We can evaluate CORN AND GRAIN SCREENING TECHNOLOGY effect according to the following principle:
1. TQLZ vibrating screen:
1) The effect for big impurities removing can reach 90% above, for small impurities removing by the first screen can reach 65% above, and the effect for the other screen can reach 50% above.
2) The effect for sediment removing can reach 65% above.
3) The effect for light impurities removing can reach 70% above.
4) The grain content in various leftovers is less than 1%.

2. TQLM rotary flat sieve:
1) Big and small impurities removing effect can reach 80% above.
2) Light impurities removing effect can reach 60% above.
3) The grain content in the big and small impurities is less than 1% and the grain content in each gram of light impurities is no more than 1 kernel.

3. TCQY cylinder precleaner has the following technology index: big impurities removing effect can reach 90% above, and there have no whole grain kernels in the leftovers.
