Portable Trommel Screen CPT 1326
The CPT 1326 is a semi-mobile trommel screen designed for screening jobs that require frequent relocation and fast setup. Featuring a belt feeder, double-deck trommel drum, and two product conveyors, this compact unit delivers reliable performance when processing a wide variety of materials including topsoil, compost, aggregates, construction and demolition waste, biomass, and wood chips. It is especially effective when screening sticky and difficult materials.
The foldable side panels of the feed hopper allow material loading from either side, increasing flexibility on site. An optional integrated diesel or gasoline generator provides full autonomy from external power sources. Weighing only 3,500 kg (including the generator), the unit can be towed by pickups or vans, making it highly practical for urban use. It is well-suited for contractor jobs and short-term rentals, and its ability to handle almost any material makes it a favorite among rental companies and end-users a like.

Portable Trommel Screen: The Perfect Balance of Power and Portability
Portable trommel screens offer a strategic advantage for operations that require higher throughput and more refined separation than fully mobile units, yet still demand the flexibility to relocate. These versatile machines strike a unique balance between the robust performance of a stationary plant and the adaptability of a mobile solution. But what exactly is a semi-mobile trommel screen, and how can it optimize your material processing needs for superior efficiency and product quality.
A portable trommel screen is a high-capacity, heavy-duty rotary screening system designed for detailed classification of various bulk materials. Unlike fully mobile units, they might require a bit more setup time but compensate with significantly larger processing volumes, enhanced screening accuracy, and greater stability. They are typically mounted on a skid frame or a less frequently moved chassis, making them ideal for projects with medium-to-long term on-site requirements where occasional relocation is necessary. These units excel at separating sticky, wet, and challenging materials like topsoil, compost, aggregates, C&D waste, and biomass, ensuring consistent, high-quality output.
Bridging the Gap: Why Choose a Portable Trommel Screen?
A portable trommel screen stands out by offering a compelling mix of benefits:
- Elevated Throughput & Precision: Designed for larger capacities and more precise separation than many fully mobile units, ensuring higher productivity and superior product consistency.
- Optimal for Challenging Materials: Excels at handling sticky, wet, and difficult-to-screen materials that might clog traditional vibratory screens, thanks to its rotating drum action.
- Strategic Relocation Capability: Provides the flexibility to move the unit within a site or to new sites when operations shift, without the extensive dismantling required for fully stationary plants.
- Reduced Handling Costs: By processing material closer to the source, it minimizes the need for costly long-distance hauling and rehandling of materials.
- Enhanced Product Quality: The tumbling action within the trommel effectively cleans and sizes material, producing cleaner and more consistent end products.
The Heart of the Operation: How Portable Trommel Screens Work
A portable trommel screen operates around a large, rotating cylindrical drum, or “trommel.” Raw material is fed into one end of this inclined drum. As the drum slowly rotates, the material tumbles and agitates, causing finer particles to fall through the screen perforations along the drum’s length. Larger materials travel further down the drum until they exit at the opposite end.
The size of the perforations typically increases along the length of the drum, allowing for the separation of multiple product sizes in a single pass. Many semi-mobile trommels also feature internal lifters or paddles that enhance the tumbling action, ensuring effective material agitation and preventing clogging, especially with wet or sticky feeds. The separated materials are then collected via conveyors beneath the drum and stockpiled.
Beyond the Basics: Key Applications for Portable Trommel Screens
The robust design and efficient separation capabilities of portable trommel screens make them ideal for a variety of demanding applications:
- Compost & Biomass Processing: Highly effective for screening compost, wood chips, and other organic materials to produce high-quality soil amendments and fuels.
- Topsoil Production: Essential for removing rocks, roots, and debris from raw soil, yielding premium topsoil for landscaping and agriculture.
- C&D Waste Recycling: Excellent for separating mixed demolition debris, facilitating the recovery of aggregates, wood, and other recyclable materials.
- Sand & Gravel Quarries: Used for washing and sizing aggregates, especially when dealing with clay or highly contaminated material.
- Land Remediation & Site Preparation: Ideal for processing excavated materials on contaminated sites or for large-scale earthmoving projects.
Optimizing Your Investment: Selecting the Right Portable Trommel Screen
Choosing the right portable trommel screen is crucial for maximizing your operational efficiency and return on investment. Consider these vital factors:
- Material Characteristics: Assess the type, moisture content, stickiness, and desired output sizes of the material you’ll be processing. This directly impacts drum design and screen media choice.
- Throughput Requirements: Determine your desired hourly processing capacity to ensure the trommel can meet your production demands.
- Screening Accuracy & Number of Products: Decide how many different material sizes you need to separate and the level of precision required for each.
- Mobility vs. Stability Needs: Evaluate how often the unit will need to be moved and the nature of the terrain, balancing mobility features with required operational stability.
- Power Source & Efficiency: Consider engine type, fuel consumption, and whether electric or diesel power is more suitable for your site.
- Maintenance & Accessibility: Look for designs that allow for easy access to wear parts, simple drum changes, and straightforward routine maintenance.
