Application Of Vibrating Screen In Seed Screening.

The screening effect of vibrating screen has very important influence on the quality of seeds and the output of finished products. The application of screening technology in seed processing and production focuses on two aspects: one is to coarse screen the large impurities in the raw materials through the vibration screen; the other is to remove the not full and withered seed raw materials through the vibration screen, including the cleaning of fine sand, soil and other powder impurities in the seed raw materials.

1. Application of vibrating screen in removing impurities from coarse sieve of seed raw materials


The seeds are directly from the field and contain complex impurities. There are mainly two kinds of impurities: one is the impurity with larger grain size than the grain, such as corn cob, hemp, straw, twine, plastic, etc. The impurity removal is mainly based on the different kinds and particle sizes of the impurities in the seed raw materials.


2. Application of vibrating screen in fine sieve of seed material


After the removal of impurities in the seed raw materials are still mixed with soil and fine sand and other fine powder impurities. At this time, it is necessary to carry out a second fine sieve, after which the seeds can be weighed and packed.
