Our Gravity Separator Advantages
Enhanced Surface Protection
All carbon steel parts are treated with acid pickling and phosphating, forming a uniform 8–12 μm base layer to improve coating adhesion.
An industrial-grade 60–80 μm coating further enhances corrosion resistance, ensuring long-term durability in dusty, humid, and continuous-operation environments.
Enhanced Efficiency & Capacity
Square wire screens across all decks increase surface friction and stabilize material movement.
This improves stratification efficiency and enables higher throughput per square meter without compromising separation accuracy.
Enhanced Manufacturing Process
An upgraded welding process creates cleaner joints and a more rigid overall structure.
Seamless aluminum air vents add corrosion resistance and strength while maintaining a clean, refined finish.
Less Maintenance and Operating Cost
Separating the motor from the fan limits dust exposure to critical components, improving operational reliability.
Standard motors simplify maintenance and replacement, helping reduce service time and long-term operating costs.
High Airflow for Versatile Applications
With an independently driven fan, higher airflow is available for effective separation of light materials as well as heavier products.
This allows the machine to perform reliably across a wide range of cleaning and grading applications.

Common Questions
Most Popular Questions.
Not sure which configuration fits your material? Our technical team can help.
The machine is designed for durability through an independent motor structure and the use of phosphated carbon steel components. This design reduces mechanical stress, improves corrosion resistance, and ensures stable operation over long-term, continuous use.
The motor is installed separately from the airflow system, minimizing dust ingress. Even in dusty working conditions, this design helps protect the motor, reduce unplanned downtime, and lower overall operating and maintenance costs.
No. The motor uses a standard, independent design, making replacement simple and fast. Standard motors are widely available and cost-effective, helping reduce both maintenance time and replacement costs.
Yes. Strong, stable airflow ensures proper stratification for both light grains and heavier or irregular materials, enabling consistent separation across different crops.
Yes. The design focuses on stable operation, easy adjustment, and reduced maintenance, allowing the machine to run continuously with minimal interruptions.
