Starlight Environmental Intelligence Solves Screening Challenges of Wet, Sticky, and Entangling Materials with Shaftless Trommel Screen

2026-04-26 10:58:29

In industries such as solid waste processing, mining, sand and aggregate production, and construction waste recycling, screening wet, sticky, or easily entangled materials has long been a major bottleneck for production efficiency. Traditional shafted screens are prone to clogging, material wrapping, frequent maintenance, and limited throughput—driving up operational costs across the entire production line.

Hebi Starlight Environmental Intelligence, a specialist in screening equipment, has tackled these pain points head-on with its core product—the shaftless trommel screen. From structural design to manufacturing processes, the company delivers efficient, stable, and hassle-free screening solutions tailored to complex materials.

1. What is a Shaftless Trommel Screen?

The shaftless trommel screen eliminates the central shaft and relies on external support rollers or gears to rotate the screen cylinder. Material enters from one end and moves forward slowly as the cylinder rotates and tilts. Fines pass through the screen, while coarse material is discharged from the opposite end. This integrated process achieves dispersion and screening in one step, without requiring additional breaking equipment.

Compared to traditional shafted trommels, this design fundamentally avoids issues such as material wrapping around the central shaft, screen hole clogging, and frequent maintenance, making it ideal for complex screening applications.

2. Five Core Advantages That Lead the Industry

A. Clog-Free Design for Complex Materials
With no central shaft to obstruct flow, material tumbles freely inside the cylinder, ensuring effective dispersion. Even wet coal, sludge, aged waste, or fibrous materials with moisture content up to 30% can be screened smoothly without wrapping or clogging. Built-in comb cleaning and self-cleaning mechanisms keep screen holes open, enabling continuous operation without shutdowns—significantly improving production continuity.

B. High Throughput and Efficiency
Removing the central shaft increases the effective screening area, boosting throughput by 20–35% compared to shafted screens. Single-unit capacity ranges from 50 to 800 t/h, suitable for small, medium, and large production lines. Screening accuracy remains stable at 90–95%, ensuring precise material classification and high-quality end products.

C. Extremely Simple Structure with Low Maintenance
The modular design has no central shaft, fewer bearings, and fewer wear parts, reducing failure rates. The screen mesh can be replaced in as little as 30 minutes, and individual screen plates can be swapped without dismantling the entire machine. Maintenance time and costs are reduced by up to 60%, and the equipment is easy to operate even for new users.

D. Durable and Reliable with Extended Service Life
The screen cylinder is made of high-strength wear-resistant steel or manganese steel, with screen plates produced via laser cutting and precision punching, offering excellent impact resistance and wear resistance even with large materials. Core components such as support rollers, gears, and chains are sourced from high-quality suppliers, resulting in a service life 3–5 years longer than ordinary equipment.

E. Environmentally Friendly and Low Energy Consumption
A fully sealed design prevents dust leakage and minimizes fugitive emissions, fully complying with environmental production standards. With low-power motors, energy consumption is reduced by half to two-thirds compared to traditional equipment, while operational noise is lower—safeguarding environmental compliance and reducing daily electricity costs.
