Cases

XUANYU trommel sieving solution for composts is a heavy-duty, clog-resistant rotary screening system designed for high-moisture, sticky composts, integrating multi-zone screening, self-cleaning mechanisms, and optional purification modules to deliver consistent particle sizing and impurity removal for organic fertilizer production and compost valorization.

Core Solution Overview

Tailored to the challenges of composts (e.g., food waste, green waste digestate) with high moisture, viscosity, and contaminants, the solution features:

• Trommel Drum Design: Inclined rotating drum (3°–5° slope) with internal lifters to agitate and disperse sticky materials, minimizing blockages.
• Multi-Zone Screening: 1–3 screen sections with customizable hole sizes (5–50 mm typical) to separate finished compost (5–20 mm), oversize material (recycled for re-composting), and large contaminants (removed).
• Wear-Resistant Materials: Abrasion-resistant carbon steel or 304/316 stainless steel screens and liners, corrosion-proof and easy to clean, meeting organic fertilizer hygiene standards.
• Self-Cleaning System: Adjustable drum speed (3–8 rpm) and internal cleaning plates prevent wet material clogging; optional spray system for wet sieving applications.
• Integrated Modules: Optional magnetic separator (for metal removal), conveyor system, and dust collection unit for seamless integration into automated composting lines, with PLC control for operational consistency.

Technical Specifications (Typical)

表格

Screening Process

• Feeding: Compost is evenly fed into the drum via a hopper or belt conveyor to avoid overloading.
• Screening: As the drum rotates, lifters lift and drop the material, separating fines (finished compost) through the screen, while oversize material and contaminants move to the discharge end.
• Purification: Magnetic separation removes metal impurities; dust is collected by an integrated dust collector to meet environmental standards.
• Discharging: Finished compost is collected for packaging or storage; oversize material is returned for re-composting; contaminants are discarded.

Core Advantages

• High Efficiency: Self-cleaning design reduces downtime for screen cleaning, with screening efficiency ≥90%.
• Stable Quality: Precise sizing ensures uniform particle size, enhancing the application effect of organic fertilizers/substrates.
• Durability & Low Maintenance: Robust construction withstands harsh environments, with minimal wear and easy screen replacement.
• Flexibility: Mobile or fixed design options to suit different sites and capacities; quick screen changes for multiple specifications.
• Eco-Friendly: Sealed design and dust collection system reduce dust and odor emissions, complying with environmental regulations.

Sizing Recommendations

表格

Scenario	Recommended Model	Screen Configuration	Notes
Small-scale organic fertilizer plant (1–5 t/h)	1.2×3.0 m trommel	10–20 mm, 1–2 zones	Compact, easy maintenance
Large-scale composting center (5–10 t/h)	1.8×6.0 m trommel	5–30 mm, 2–3 zones	High capacity, multi-stage screening
Garden substrate preparation	Mobile trommel (1.0×4.0 m)	5–15 mm, 1–2 zones	Flexible for on-site operation
