Smart Trommel Screen for Automated Metal Separation Line

The Trommel Screen is a classic, versatile particle size classification device. It is widely used in environmental sectors such as metal recycling and solid waste recovery, as well as industries like power generation, coking, construction materials, metallurgy, and mining.

Featuring a modular structure for flexible adaptation to diverse scenarios, its core design combines drum rotation with multi-layer screening to achieve efficient material classification. The compact and robust structure includes wear-resistant rubber drive wheels and a fully enclosed screening chamber. With low noise, energy efficiency, and high throughput, it is a reliable solution for industrial screening.

​Note: Both "output" and "rotation speed" should be adjusted based on actual material conditions.

Material enters the trommel screen through the feed inlet and is lifted by drum rotation to a certain height, where gravity causes it to fall freely. Particle size classification is achieved through multi-stage screening:

Multi-Stage Refinement:Subsequent layers progressively screen finer particles, with oversized material discharged from the end outlet.

Primary Screening: Particles smaller than the first-layer screen apertures drop into the corresponding hopper, while larger particles advance.

The self-cleaning action is driven by friction between the material and drum, combined with built-in cleaning brushes, ensuring continuous operation even with wet or adhesive materials.

Shaftless design cuts footprint, customizable drum configurations (octagonal, cylindrical, double - layer).  Handles sand, coal slag, construction debris, etc.

Armor-Clad Screens: High-manganese steel withstands rock impacts (lifespan over 10,000 hours).

Rubber drive wheels and polyurethane rollers reduce noise.
30% lower power consumption vs traditional equipment, fully sealed design for zero dust leakage, and integrated dust removal ensuring one-pass environmental approval.

Frequency converter for real-time speed adjustment with different materials.
Automatic overload shutdown protection. only monthly lubrication for routine maintenance.

metal Recycling: Recycled aluminum raw material sorting lines, post-shredder scrap steel residue separation, e-waste processing.

Waste Management: Incineration slag sorting lines, recyclables recovery centers, construction waste-derived aggregate production.

Ore Pre-Screening & Enrichment: metal ore preprocessing, sand/aggregate size classification.
Process Optimization: Tailings reprocessing, sintered ore screening.
