At States Engineering, we understand the challenges foundries face when it comes to maintaining efficiency while ensuring high-quality sand processing. That’s why we designed the Rotary Screen—an innovative solution to improve sand purity, remove contaminants, and optimize your operations.
Why Efficient Sand Screening Matters
In any foundry operation, maintaining the integrity of return sand is crucial. Tramp materials, core butts, and debris can compromise casting quality, lead to increased defects, and cause excessive wear on equipment. Traditional screening methods often involve high-maintenance vibrating screens, which can be noisy, inefficient, and prone to breakdowns.
Our Rotary Screen offers a low-maintenance, high-efficiency alternative that seamlessly integrates into your existing system, providing a reliable and cost-effective way to maintain superior sand quality.
How the States Engineering Rotary Screen Works
The Rotary Screen operates using a simple yet highly effective design. Here’s how it enhances your foundry’s workflow:
- Optimized Sand Flow – Return sand is conveyed via a bucket elevator or belt conveyor into the receiving chute, directing it into the rotating drum.
- Superior Screening Mechanism – The drum’s lifting flights elevate and tumble the sand, ensuring thorough and efficient separation of unwanted materials.
- Reduced Maintenance – Unlike high-speed vibrating screens that require frequent upkeep, our Rotary Screen rotates at a slow 14 RPM. This minimizes mechanical wear and extends the equipment’s lifespan.
- Integrated Dust Control – The enclosed design includes an exhaust outlet that connects to your dust and fume collection system, improving air quality in your facility.
- Enhanced Safety Features – The screen’s electrical safety interlocks automatically shut down the unit when inspection doors are opened, ensuring operator safety.
Key Advantages of the Rotary Screen
1. Improved Sand Purity
By efficiently removing debris, our Rotary Screen ensures only clean sand is recirculated, reducing the risk of defects in castings.
2. Cost-Effective Operation
With minimal moving parts and foundry-duty spherical roller bearings, our screen significantly lowers maintenance costs and downtime.
3. Customizable for Your Needs
We offer standard and custom sizes to meet specific operational requirements. Various screen cloth materials and opening sizes are available to accommodate different applications.
4. Indoor & Outdoor Versatility
Our durable design ensures reliable operation in both indoor and outdoor settings, with protective coatings for long-term durability.
