Product Details

Heavy Duty Trommel Screen (Rotary Drum Screen)

The Trommel Screen is the most effective equipment for washing and grading materials containing clay or sticky soil. It is the "Heart" of many Alluvial Gold Ore Production Lines.

Unlike static screens, the Trommel rotates to lift and drop the material (tumbling action). This effectively breaks up clay and scours the ore, making it perfect for processing River Sand, Placer Gold, and Municipal Solid Waste.

Working Principle: Tumbling & Screening

The material is lifted by the rotating drum and dropped by gravity, ensuring thorough separation.

Feeding & Scrubbing

Raw material is fed into the rotating drum (often via a vibrating feeder). High-pressure water jets inside the drum wash away clay and mud.

Sizing Separation

Fine materials pass through the screen apertures (mesh). We can install 1-3 layers of mesh to get different output sizes simultaneously.

Discharge

Oversized rocks are discharged at the tail. The fine slurry flows to downstream equipment like the Sawtooth Wave Jig or Spiral Chute.

Heavy Duty Trommel Screen Structure

Technical Choice: Trommel vs. Vibrating Screen

Which screening equipment is right for you? It depends on your material condition:

Feature	Trommel Screen (Rotary)	Vibrating Screen
Material Type	Sticky, Clay-rich, Wet.	Dry, Clean, Crushed Rock.
Function	Washing + Screening.	Sizing / Grading mainly.
Alternatives	Use Rotary Scrubber for heavy clay.	Use circular vibrating screen for quarry.

Core Advantages

1. Anti-Clogging Design

Equipped with a cleaning brush or beating mechanism on top of the drum to prevent screen blinding, ensuring continuous efficiency.

2. Versatile Mesh

We use High Manganese Steel woven mesh or punched steel plates. Durable and easy to replace for different sizing needs.

3. Smooth Operation

Heavy-duty gear drive or rubber tire drive ensures low noise and stable rotation, even with heavy loads (up to 260t/h).

Typical Applications

● Alluvial Gold Mining:
Washing clay-rich gold ore for Alluvial Gold Production Line.
● Sand & Gravel:
Classifying material after Jaw Crusher for Quartz Sand Production.
● Tin Mining:
Pre-screening for Tin Alluvial Ore Production Line.
● Waste Management:
Separating soil, bricks, and plastic in municipal solid waste recycling.

Frequently Asked Questions (FAQ)

Q: Can it be mobile?

A: Yes! We manufacture both Stationary and Mobile Trommel Screens (mounted on wheels with a diesel generator), perfect for remote mining sites.

Q: How do I choose the screen mesh size?

A: It depends on your gold particle size. For placer gold, the inner layer is typically punched plate (10-20mm) to protect the outer layer, and the outer layer is woven mesh (3-6mm) for fine separation.

Q: What is the angle of installation?

A: The drum is usually installed at an inclined angle of 6° to 14°. This allows the material to move forward by gravity while tumbling for efficient screening.
