Fractional separator
The high-efficiency Fractional Separator FS-4 is specially engineered for particularly precise and gentle calibration of all types of grain crops, legumes, and grass seeds. It offers high throughput combined with exceptional processing quality.
Unlike standard separators with inclined screen decks (where material rapidly slides down under gravity, restricting operation to basic secondary cleaning), the FS-4 utilizes a horizontal multi-deck arrangement to achieve true, precise sizing and calibration.
Features & Advantages of the FS-4 Fractional Separator
Key technological advantages of our fractional separator include:
- Massive Screen Deck Area (8.8 sq.m): Multi-level horizontal sieve layout ensures maximum contact time between seed material and calibration screens;
- 3, 5, or 7 Fraction Separation: Versatile separation options tailored to meet strict seed purity and sizing requirements;
- Highly efficient self-cleaning sieve system that prevents blinding during continuous operation;
- Quick-change screen mechanism for effortless reconfiguration across different agricultural crops.
Application in Seed Processing Lines
The FS-4 separator is an optimal solution for commercial seed preparation plants, where uniform kernel weight, precise sizing, and high germination rates are essential for premium crop yields.

Frequently Asked Questions About Fractional Separators
Why are horizontal sieves more effective for precise calibration than inclined sieves?
On inclined sieves, the product quickly moves down due to gravity, preventing thorough size grading. The horizontal multi-level deck design of the FS-4 ensures that grain remains on the 8.8 sq.m screen surface long enough to yield accurate size separation.
How many fractions can the machine separate into?
Depending on the installed screen frames and operational requirements, the FS-4 fractional separator can divide material into 3, 5, or 7 distinct fractions.
