Industrial Trommel Screen Machine: Heavy-Duty Shaftless Sorting

High-Volume Sizing for Complex Waste Streams

The Trommel Screen Machine is the gatekeeper of any waste sorting line. Its job is to ensure precise particle size separation before the material hits high-value sensors like NIR or Eddy Current separators.

Guoxin Machinery’s shaftless trommel design is specifically engineered for “difficult” materials. By eliminating the central shaft, we prevent long-strip contaminants—such as plastic films, ropes, and textiles—from wrapping around the rotor and causing unscheduled line shutdowns.

High-Availability Design: Built for Continuous Heavy-Duty Cycles

Engineered for high-abrasion environments, the GTS series combines heavy-duty mechanical structure with anti-clogging features to maximize plant uptime:

Shaftless Friction Drive & Composite Rollers:Driven by heavy-duty friction wheels with a thick-walled rolling ring. The load-bearing wheel cores are coated with high-strength polyester composite material, delivering extreme resistance to acid, alkali, and wear while maintaining low operational noise (≤85dB).

16mm Reinforced Drum Structure:Unlike standard thin-walled screens, our drums are fabricated from 16mm high-tensile steel plates with surface-strengthened keels, providing the structural rigidity needed for heavy C&D debris and abrasive mineral slag.

Anti-Clogging Mechanism for Wet Waste:Equipped with internal material lifters, specialized scrapers, and optional cleaning brushes to ensure screen openings remain open and functional when handling high-moisture organic waste.

Modular Screening & Multi-Zone Separation:Features customizable drum screen zones (e.g., 30mm for organics and 80mm for combustibles) to achieve 3-way material separation in a single pass. Modular screen plates allow quick section replacement without dismantling the main drum assembly.

Technical Specifications of GTS Series Shaftless Waste Trommel Screen

Application-Specific Sorting

1. Municipal Solid Waste (MSW): Efficiently separates the organic fraction ($<$40mm) from high-calorific recyclables.

Integrated into our complete [turnkey municipal solid waste sorting plant] systems for primary size fractioning.

1. Construction & Decoration Waste (C&D): Removes soil and fines to clean the stone and brick fractions for secondary crushing.

Widely specified in our heavy-duty [construction waste sorting machine] processing lines.

1. Aged Landfill Waste: High-torque rotation breaks down compacted clumps of soil and trash for land reclamation.

2. Abrasive Materials: Our polyester composite coating on load-bearing rollers provides extreme resistance to acid, alkali, and wear.

Shaftless vs. Traditional Shafted Trommel Screens: Why Design Matters for Waste

• Shaftless Design (Guoxin GTS Series): Zero center shaft, completely open internal space. Eliminates bag and film wrapping; ideal for mixed MSW, C&D waste, and sticky organics.
• Traditional Shafted Screens: Central axis acts as a magnet for long fibers, requiring frequent manual cleanouts and causing severe belt wear.

FAQ

Q: Why use a shaftless design instead of a central shaft? A: Central shafts act as magnets for bags, ropes, and wires, causing “wrapping” that stops production. The shaftless design provides a clear internal path, increasing throughput and decreasing manual cleaning time.

Q: How long does it take to replace a screen plate? A: Our modular plate design allows for individual section replacement without dismantling the entire drum. A standard section can be swapped by two technicians in under 2 hours.

Q: Can you handle wet material with 50% moisture? A: Yes. We add specialized internal “scrapers” and vary the drum angle to ensure wet, sticky waste moves through the screen rather than balling up.
