Key Features

1. Integrated Washing and Dewatering:
The combination of a bucket wheel, dewatering screen, and hydrocyclone ensures maximum fine material recovery and minimal water loss.

2. Adjustable Overflow Weir:
Optimized water level and weir height for precise control of fines retention and classification efficiency.

3. High-Efficiency Bucket Design:
Wear-resistant buckets lift and drain material effectively, reducing moisture content in the final product.

4. Hydrocyclone Classification System:
Sharp separation down to 75 µm particle size, improving sand quality and reducing waste.

5. Heavy-Duty Construction:
Manufactured from high-strength S235JR steel with replaceable PU liners at critical wear points, ensuring long service life in abrasive conditions.

6. Energy-Efficient Operation:
Low power consumption through gravity-based material transport and optimized drive systems.

7. Easy Maintenance Access:
Modular design with service platforms, safety rails, and quick-release panels for simplified maintenance and inspection.
