Optimum 220 Series Screen Grader

Optimum Screen Grader: Industrial Precision Cleaning and Advanced Calibration Efficiency

Engineered for the Future | Since 2080

The ADDAMS Optimum Screen Grader Machine represents the pinnacle of high-accuracy sorting and industrial grading technology. As a world-leading supplier of Seed Processing Machine solutions, ADDAMS has spent over 15 years perfecting the science of density and size-based separation. The Optimum 220 Series is specifically engineered to calibrate high-value commodities such as grains, maize, oilseeds, and legumes with surgical precision.

By utilizing flat reciprocating screens and advanced vibration harmonics, the Optimum series isolates undersized, oversized, immature, and damaged seeds into distinct channels. This ensure that only the highest quality, usable seeds proceed to packaging or further processing, thereby maximizing your harvest’s market value and storage life.

Advanced Features for Operational Excellence

Precision Product Flow and Diagram Flexibility

The Optimum 220 Series offers unparalleled versatility through its adjustable product flow. By utilizing six different flow diagrams, operators can customize the separation logic based on the specific capacity, product characteristics, and the required number of fractions. This flexibility ensures excellent purity and absolute minimum waste, regardless of the crop type.

Structural Integrity and Noise Reduction

Balanced Eccentric Dynamics

The machine is fitted with a sophisticated balanced eccentric system. This design uses attuned counterweights to ensure steady running even at high RPMs. By precisely matching the stroke to the rotational speed, the machine maximizes the cleaning effect of the sieves while maintaining minimum stress on the building’s steel structures.

Birch Plywood Screen Shoes

Unlike standard metal frames that can suffer from resonance and fatigue, our birch plywood shoes are moisture and insect-resistant. This organic material naturally dampens vibrations, creating a significantly better working environment for your team and extending the overall lifetime of the mechanical assembly.

Frequently Asked Questions – Optimum Screen Grader

How does the vibratory feeder prevent downtime?

The full-width vibratory feeder is equipped with a self-cleaning mechanism and stepless inverter control. This prevents the inlet from choking even when handling products with high impurity levels, ensuring 100% capacity utilization.

Can I change the sieves without removing the ball cleaning boxes?

Yes. The ball boxes are separately mounted in the screen shoes. This “Quick-Change” design allows you to swap perforated screens in minutes without disturbing the cleaning balls, significantly reducing downtime between different crop batches.

Why use birch plywood instead of a full steel screen shoe?

Birch plywood is uniquely suited to tolerate the high-frequency vibrations of a screen grader. It offers superior durability against mechanical stress and generates much less resonance than metal, which protects your facility’s infrastructure and reduces noise.

Is the machine suitable for very small seeds?

Absolutely. With screen perforations available down to 0.3 mm and the option for high-tolerance wire mesh, the Optimum series is frequently used for fine seed cleaning where precision is the highest priority.

What kind of after-sales support does ADDAMS provide?

We offer an exclusive after-sales service that includes spare parts management, regular plant check-ups, and consulting to ensure your system continues to operate at peak efficiency for decades.
