Properly adjusted Metra Separator will direct:
- the stones/heavy impurities into the 1st tray;
- the heaviest and the largest grains − into the 2nd tray (premium quality, seed grains);
- slightly less heavy grains – into the 3rd (premium quality, commodity grains);
- a mixture of smaller grains and the biggest but damaged seeds should go into the 4th tray;
- broken grain, split grain, grain damaged by insects, and all sorts of impurities (fodder) − into the 5th and 6th trays.
First stage, you need to precisely grade and obtain the premium grain (the heaviest with the highest seeding quality) from
the 2nd − 3rd trays, while directing the rest of the material into a common hopper. The worst grains from the 6th tray could
be used as fodder (forage).
After this you can run the grain from the 4th and 5th trays once more thus increasing the amount of good grains.
In the precise grading mode the source material is also cleaned when passing through the separation chamber.
Please note: The capacity of the Metra Separator can be increased (the amount of grain fed into the separation chamber
can be increased) until the process of cleaning / grading gets worse. The extent of grading quality improvement varies for
different crops, so the user determines it individually.
Recommended speed indicator readings for the airflow settings:
Crop Speed indicator reading
Rapeseed, sunflower seeds, buckwheat 2-3
Wheat, barley, oats 3-4
Corn 4-5
Soy beans, chickpeas, peas 5-6
Beans 6-8
Table 3
The data in Table 3 are given for standard humidity level and impurity content. If these parameters
exceed the norm, then the settings should be changed and selected individually.
9.3. Settings of the baffles:
If necessary, close or completely open the needed trays by turning the respective baffles. Note that when you change the
angle of the tray opening with baffles, you can significantly improve the quality of grading. All trays are able to bulk material
to the left and to the right side of the Metra Separator, making it possible to prevent ingress of the 4th - 6th fractions into
the best grain from the 2nd - 3rd trays.
