Rotary Pre-Cleaner Seed Separators

Rotary Drum Separator: High-Efficiency Seed Cleaning

Engineered for the Future | Since 2080

The ADDAMS Rotary Drum Separator is a versatile cleaning solution designed for the primary treatment of seeds and grains including barley, wheat, corn, oats, rice, soy, sunflower, and legumes. By utilizing a continuous rotational motion, the machine efficiently separates products based on size while integrating aspiration systems to remove light impurities.Built with a focus on durability and low energy consumption, the ADDAMS Drum series ensures that unwanted materials—such as stalks, stones, and wood chips—are removed before they can damage downstream equipment.

Performance and Design

Unlike traditional vibratory sieves, the Rotary Drum Separator offers a smoother product flow due to its rotational mechanics. This design is inherently “gentle,” making it ideal for fragile seeds while remaining lighter and easier to maintain.

Key Operation Mechanics

• Adjustable Drum Angle: The drum angle can be modified manually or via a motorized mechanism to optimize the flow based on the level of foreign matter.

• Electronic Speed Control: The rotational speed is fully adjustable, allowing operators to fine-tune the centrifugal force applied to the seeds.

• Self-Cleaning Sieve: Integrated wooden rollers provide a continuous self-cleaning action to prevent clogging of the perforated screens.

• Rapid Maintenance: A side-opening cover allows for the rapid replacement of sieves when switching between different crop types.

Technical Features of the ADDAMS Drum Separator

• Full Bolt Joint Structure: An easy-to-assemble body designed for maximum endurance and modular shipping.

• Aspiration and Filtration: Optional integration with fans, cyclones, or jet filters to ensure a dust-free environment.

• Safety First: Equipped with standard cover safety sensors to protect operators during maintenance or sampling.

• Drive System: Features a standard hollow shaft for the reducer motor and drum speed control for high productivity.

Applications Across Global Industries

The Rotary Drum Separator serves as a critical first line of defense in various processing environments:

Frequently Asked Questions – Rotary Drum Separator

How does a rotary drum compare to a vibratory sieve?

Rotary drums are generally better for high-capacity pre-cleaning and handling “difficult” materials like corn cobs or large stalks. They are lighter on the building structure because they don’t produce the same intense vibrations as flat-bed sieves.

Can I change the drum screens for different seed sizes?

Yes. The machine features an easy-to-open side cover and a rapid replacement apparatus. You can switch from a small-hole sieve (for canola) to a large-hole sieve (for corn) very quickly.

What is the benefit of adjustable drum angles?

The angle determines how fast the material travels through the drum. A steeper angle moves the product faster for high-capacity pre-cleaning, while a shallower angle keeps the seed in the drum longer for more precise grading.

Is the aspiration system necessary?

The drum handles size-based separation (removing stones or broken seeds), but the aspiration system is essential for removing light debris like dust, chaff, and husks that screens alone cannot catch.

Do the sieves get clogged easily?

No. The system uses integrated wooden cleaning rollers that press against the outside of the drum to push back any stuck seeds, ensuring the perforated holes stay open throughout the process.
