The trommel screen is primarily used to remove dust and clay mixed with copper scrap. This treatment helps reduce the amount of slag and copper loss during the copper refining process.
It plays a crucial role in pre-treatment before smelting or melting, improving the overall quality of copper input and enhancing the efficiency of downstream refining operations.
By ensuring cleaner copper scrap, it not only reduces processing costs but also increases metal recovery rates.
The trommel screen is mounted on the frame in a tilted manner. The motor drives the trommel unit to rotate around its axis through a reducer. When entering the trommel, the material will tilt and roll under the rotation of the trommel unit. The qualified material will be discharged through the material outlet at the back bottom of the trommel, while the unqualified material will be discharged through the outlet at the rear of the trommel.
The flipping and rolling of materials inside the trommel screen help to eject any materials that may get stuck in the screen holes, preventing blockages.
This rolling motion not only separates finer particles but also continuously cleans the screen surface, maintaining efficient throughput without manual intervention.
Different mesh sizes can be applied at each section of the drum, enabling a step-by-step screening process based on particle size.
Segmented Screen Design
The cylinder of the trommel screen is usually divided into multiple sections. The holes are arranged from small to large, and each section has the same aperture size for its screen holes.
This progressive screening ensures accurate separation of materials, from fine dust to larger clay particles, enhancing screening accuracy and minimizing the carryover of impurities.
Efficient Separation
The trommel screen is designed to efficiently separate dust and clay mixed with copper scrap, significantly reducing slag formation and copper loss during refining.
Cleaner copper feedstock results in higher purity end-products and reduces the need for costly refining additives.
Self-Cleaning Operation
The continuous rolling motion inside the drum helps eject any materials that may block the screen holes.
This self-cleaning mechanism ensures minimal downtime, low maintenance, and consistent operational efficiency.
Robust and Low-Maintenance Design
Built with wear-resistant materials and a reinforced frame, the trommel is suitable for continuous operation in harsh industrial environments.
Low vibration and low noise during operation make it ideal for copper scrap yards and recycling facilities.
