Drum pre-cleaner KDC 4000

Pre-cleaner KDC 4000 cleans the crop with rotating screens and air. These two stages cleaning process ensures that both heavy and light impurities are removed.

The KDC 4000 can also be used for cleaning and grading malting barley. Malting barley can be delivered to market completely clean directly from farm and barley not suitable for malting can be utilized for feed. Furthermore it is possible to use the KDC 4000 for cleaning to seed quality.

The wide range of screens options available for the KDC 4000 ensures there are screens for most crops and desired capacities and cleaning level.

It is important to remember that during the cleaning process, the commodity has to pass through a set of screens forming the inner drum. The selection of inner screens will determine the amount of large impurities that are removed as well as capacity. It should be noted that the smaller the perforation of the screen is, the more large impurities are removed, but at a reduced overall capacity.

Inner screens with larger perforation increase the capacity, but do not remove as high an amount of impurities.

The screens on the outer drum retain the crop. So, the perforation of the outer screen determinate how much of the foreign material (small impurities) will be released.

The larger perforation on the outer screens, the cleaner the crop will be, however, smaller good grains can be released if too large perforation is selected.
