Trommel Screen (Rotary Drum Screening Machine)
Capacity: 50-450 t/h | Shaftless Drum Screen Separator | Max Feed Size: ≤500mm
The Trommel Screen (also known as the shaftless rotary trommel screen machine) is a high-efficiency screening equipment specifically engineered by Shandong Hengtai Intelligent Manufacturing for classifying large-sized and sticky materials. By utilizing a unique centerless shaftless drum structure and a variable frequency rotating drum screening system, the raw materials are continuously tumbled and separated as the industrial trommel screen rotates at low speeds. It is widely used across mining, building materials, coal mining, construction waste sorting, and chemical engineering industries.
Our heavy-duty drum screening machine excels in handling difficult coarse mineral blocks and sticky materials with particle diameters ≤500mm. It completely avoids mesh blinding issues common in traditional screening equipment, guaranteeing ultra-precise 2-to-4 layer aggregate material separation efficiency.
Key Advantages:
• High Efficiency Screening: Through its advanced shaftless layout and inclined drum structure, the material separation efficiency is elevated by 30% with unparalleled anti-blocking capacity.
• Variable Frequency Speed Regulation: Regulate the rotating cylinder speed flexibly to precisely manage material dwell time and output specification adjustments.
• Durable Wear-Resistant Structure: Main chassis welded with high-strength structural steel plate to withstand immense abrasion and heavy impact forces.
• Strong Adaptive Layout: Easily accommodates customizable mesh configurations from 2 to 4 layers to fulfill diverse multi-stage sizing demands.

Core Performance Features & Trommel Screen Working Principle
Shaftless Structure & Anti-Blocking Mechanism: The advanced shaftless cylinder profile combined with an optimal inclined path layout forces sticky large lumps to tumble freely inside the drum screen separator. This layout eliminates mesh blind spots, guaranteeing material separation efficiency ≥85%.
Variable Frequency Precision Sorting: Outfitted with an intelligent frequency inverter layout. Users can dynamically fine-tune the drum screening machine rotation parameters according to real-time aggregate characteristics to acquire the most accurate product classification.
Low Noise & Energy Saving: Operates at an eco-friendly noise threshold of ≤75dB. The balanced kinematic architecture reduces overall power usage by up to 15% compared to antiquated mechanical screen designs.
Heavy-Duty Durability & Flexible Mounting: Formed using premium wear-resistant steel plates to thrive under continuous heavy industrial fatigue. Supports both standard fixed structural foundations and portable wheel-mounted mobile configurations.
Technical Specifications
* Note: The final material separation efficiency and processing throughput are dynamically influenced by raw aggregate properties, customizable mesh size, and cylinder rotating parameters.

Yes! Unlike a high-frequency vibrating screen which can suffer from blinding when dealing with mud, the shaftless rotating drum screening system is exceptional at separating high-moisture, muddy, and sticky aggregate matrixes without clogging.
The rotating drum screening system lifts and drops material through gravity. Thanks to this low-impact, rotating method, operational noise stays below ≤75dB, ensuring a much quieter workspace than heavy traditional vibratory separation setups.
Thanks to our robust shaftless engineering, the maintenance interval is incredibly prolonged. Daily upkeep is basic and straightforward, mostly involving occasional washing of the customizable mesh and monitoring internal lining plates.
