Description
The tubular screen or rotary screen, also known as a tubular screen or rotary screen (or trommel), is a high-efficiency industrial machine designed for the separation, filtration and classification of solid materials by particle size. Bartly rotary screens and tubular screens or sieves are engineered for demanding applications and are widely used in the biomass, wood, recycling, composting, pellet, forest residue industries and in processes for the recovery of industrial by-products.
Custom Design and Manufacturing
Each rotary screen is custom-designed and manufactured by Irmach according to the specific needs of each client and application. The tubular construction and rotary design ensure high robustness, durability and low maintenance cost, guaranteeing continuous and stable operation even under heavy industrial loads.
Operation and Screening Principle
The rotary screening system is based on the controlled rotation of a perforated drum, which enables efficient separation of materials according to particle size. The constant drum movement promotes uniform material distribution and prevents clogging, increasing productivity and the quality of the final product.
Configurations and Accessories
Bartly tubular screens can be equipped with:
- Interchangeable meshes with different perforations
- Dust extraction systems
- Automatic discharge and variable speed control
- Integration into automated production lines
Construction and Durability
Manufactured from high-strength steel and components sized for intensive use, Irmach rotary screens stand out for their reliability, versatility and operating precision. Each unit is designed to offer the ideal balance between energy efficiency, technical performance and ease of maintenance.
Applications
- Biomass and forest residues
- Wood and wood by-products
- Composting and pellets

Frequently Asked Questions about Rotary Screens
What is the difference between a rotary screen and a tubular screen?
The rotary screen and the tubular screen refer essentially to the same type of equipment, differing mainly in shape and terminology. Both ensure efficient particle-size separation and are widely used in biomass, wood and recycling processes.
Which sectors use Irmach rotary screens?
Irmach rotary screens are used in biomass, wood, recycling, composting, pellet and forest residue industries, as well as in processes to valorise industrial by-products. Thanks to their robust and versatile design, they adapt easily to different materials and particle sizes.
Do rotary screens require a lot of maintenance?
No. Bartly rotary screens are built from high-strength steel with components sized for intensive use. They only require periodic preventive maintenance, ensuring durability, low operating cost and high reliability.
Does Irmach provide installation and technical support?
Yes. Irmach manages the entire process - design, manufacturing, installation and specialised technical assistance, offering a complete and customised solution for each client, delivered by experienced technicians in industrial rotary and tubular screens.
