Trommel Screen
Shaftless Trommel Screening Equipment | Expert in Large-Sized Material Classification
Product Overview
The Trommel Screen (also known as Shaftless Trommel Screen) is a high-efficiency screening equipment developed by Shandong Hengtai Intelligent Manufacturing for the classification of large-sized and viscous materials.
Adopting a shaftless trommel structure and a frequency conversion speed regulation system, the equipment realizes material tumbling and screening through low-speed rotation of the trommel. It is widely used in mining, building materials, coal, construction waste treatment, chemical industry and other industries.
The Trommel Screen is especially suitable for processing coarse and viscous materials with particle size ≤ 500mm, avoiding efficiency reduction caused by material blockage of traditional screening equipment, and providing accurate classification of 2–4 particle sizes.
Core Advantages
- High-Efficiency Screening: Shaftless design and inclined trommel layout increase screening efficiency by 30% with excellent anti-clogging performance.
- Frequency Conversion Speed Regulation: Flexibly adjust trommel speed to precisely control screening effect and adapt to different materials.
- Durable Structure: Welded with high-strength steel, it is wear-resistant, impact-resistant and stable in operation.
- Strong Adaptability: Supports 2–4 layers of screen mesh configuration to meet screening needs of various large-sized materials.
Applicable Materials & Application Scenarios

Core Performance Features
Shaftless Design, Anti-Clogging & High-Efficiency
Shaftless trommel structure combined with inclined layout enables free tumbling of materials inside the trommel, preventing screen hole clogging effectively. The screening efficiency is ≥ 85%, which greatly improves the efficiency of traditional screening equipment in handling viscous and large-sized materials.
Frequency Conversion Speed Regulation, Precise Classification
Equipped with frequency conversion speed regulation system, the trommel speed is adjustable to ensure precise screening according to material characteristics and meet different particle size requirements.
Low Noise, Energy-Saving, Easy Operation & Maintenance
Operating noise ≤ 75dB. Energy-saving design reduces energy consumption by 15% compared with traditional equipment. The equipment is easy to maintain, mainly by cleaning the screen mesh and checking the liner plate, reducing downtime.
High Durability, Wide Adaptability
Welded with high-strength steel, it has strong wear resistance. The equipment supports fixed and mobile installation configurations to adapt to different working environments.
