The Shaftless Roller Screen (also known as a Shaftless Trommel Screen or Non-axle Rotary Drum Screen) is an advanced industrial screening equipment specifically designed for handling sticky, wet, and high-moisture materials such as clay, shale, coal gangue, construction waste, and minerals.

Unlike traditional shaft-driven rotary screens, the shaftless structure eliminates central shaft wrapping and material tangling, significantly reducing clogging and maintenance costs while maximizing screening throughput.

Key Advantages

• 1. Anti-Clogging & Non-Twining Shaftless Design:

  Eliminates the central shaft, preventing wet clay, fibers, or bulky materials from wrapping and jamming the drum.

• 2. Modular Replaceable Mesh & Multi-Grading:

  Features customizable aperture sizes (fine to coarse grading) with quick-replace screen panels, enabling one machine to fulfill multiple sizing requirements.

• 3. Large Processing Capacity & High Efficiency:

  Incline-mounted drum structure combined with steady continuous rotation ensures full material overturning and rapid separation.

• 4. Self-Cleaning Action:

  As materials roll and tumble inside the tilted drum, clogged particles are naturally ejected from the screen mesh.

• 5. Durable Construction & Low Maintenance:

  Built with heavy-duty structural steel and wear-resistant screen plates for extended service life in demanding brick plant and mining environments.

Industrial Applications

• 1. Brick & Tile Manufacturing: Screening raw clay, shale, and coal gangue to remove oversized stones and roots before fine crushing and extruding.

• 2. Mining & Aggregates: Grading iron ore, limestone, sand, and gravel.

• 3. Waste Processing & Recycling: Separating municipal waste, compost, plastic, and construction debris.

• 4. Chemical & Metallurgy: Classifying granular and powdered industrial raw materials.
