Cleaning machines are designed for pre-cleaning the grain primarily before drying. A large admixture (straw, stones, clods of earth, etc.), fine fraction (sand, weed, broken grains, etc.) is taken from the grain by cleaning machines. Some models of cleaners are also equipped with aspirators to remove dust and light impurities.
Cleaning from coarse impurities occurs on screens with large holes (larger than grain). In our proposal there is a very wide range of sieves. The correct size of the screen is selected by our specialists together with the client. On such sieves, the grain wakes up through the holes, and the coarse fraction remains on the screen from above and is retracted.
