Trommel Screen Mesh Solutions — Screening Media Engineered for Diverse Working Conditions

Trommel screen meshes, also referred to as trommel sieves, are cylindrical screens that serve as the core screening component of trommel screen equipment. They are used for particle grading, impurity removal, and pre-treatment processes. The rotating trommel is installed at a slight incline. Material is fed into the top of the trommel. As it rotates, smaller particles pass through the apertures in the screen mesh, while larger particles are retained and continue to move along the screen mesh.

Based on varying operational requirements and material characteristics, QIUSUO offers a wide range of trommel screen mesh types in different materials and structures. These products provide excellent screening performance, wear resistance, and compatibility, effectively enhancing screening efficiency and extending equipment service life.

Factors influencing screening performance

Trommel screens typically operate at a 5° incline, offering an adjustable screening angle that enables operators to modify parameters based on material type and moisture content. Dry materials like sand, can be processed at a steeper angle for faster separation, whereas wetter materials require a shallower angle and longer residence time to achieve optimal results.

Aperture

The effectiveness of the screen mesh depends on how much smaller the particle is relative to the mesh opening. Compared to significantly smaller particles, those approximately half the size of the mesh opening (near-size particles) have a lower probability of passing through. The size of the trommel influences screening efficiency. A longer trommel provides increased residence time, enhancing separation, particularly for wet and sticky materials.

Rotational speed

Screening efficiency increases with rotational speed, reaching a maximum at approximately 50–60% of the critical speed. Beyond this threshold, efficiency declines sharply due to continued material adhesion to the screen mesh. At 75% of the critical speed, excessive agitation causes the material to disperse in the air, thereby hindering effective screening. Extremely low speeds reduce tumbling action and drop height, thereby limiting throughput.

Material velocity

The slope of the trommel, in combination with its diameter and rotational speed, determines the material movement rate and residence time. A lower slope increases the likelihood of undersized particles passing through, as they are exposed to the mesh opening for a longer duration, thereby improving efficiency.

Applications

Quarries (e.g., granite): Used for grading stone by size and for separating soil and stone dust.
Gravel sites (e.g., quartz sand): Used for sand and gravel separation.
Coal industry (e.g., coal gangue): Used for separating lump coal, coal fines, and for coal washing.
Chemical and mineral processing industries: Used for grading large and small lumps and for separating powdered materials.
Construction: Utilized by construction and demolition waste recycling facilities to separate and sort various types of materials, such as concrete, wood, and aggregates.
Municipal solid waste management: Used in waste sorting facilities to separate recyclable materials from non-recyclable waste streams.
Composting: In composting facilities, trommel screens are used to sort and separate compost materials by size, facilitating the production of high-quality compost.
Biomass processing: Trommel screens are utilized in biomass processing facilities to screen and separate wood chips, mulch, and other biomass materials.
Soil screening: Trommel screens are employed in soil screening and remediation projects to remove rocks, debris, and other contaminants from soil.
Wastewater treatment: In wastewater treatment plants, trommel screens are used to remove large solids and debris from influent wastewater prior to further processing. This helps protect downstream equipment and processes from damage and clogging.
