Self-cleaning Rotary Trommel Screen with High Screening Efficiency and Multi-stage Grading for Fertilizer Material

Designed to improve production workflow and ensure consistent fertilizer quality through efficient material screening.

The rotary trommel screen is a modern self-cleaning screening equipment that replaces traditional electric vibrating screens and ordinary mesh drum screens. Widely used for sieving solid materials with particle sizes below 300mm, it offers high screening efficiency, low noise operation, minimal dust emission, extended service life, reduced maintenance costs, and easy maintenance procedures.

This equipment is extensively applied in organic fertilizer production, mining operations, coal processing, and solid waste treatment. It effectively resolves common issues such as screen blockage, low efficiency, and high abrasion when processing sticky, wet, and messy raw materials.

• Self-cleaning design that effectively prevents screen mesh clogging for wet, sticky materials
• High screening efficiency with low dust emission and minimal running noise
• Thickened steel frame construction ensuring stable rotation and long service life
• Multi-stage grading capability to separate different particle sizes in a single operation
• Easy maintenance with simple structure and low operational costs
• Multiple models available with output capacity ranging from 1-20 t/h

Raw materials are fed into the rotating drum assembly. As the drum rotates, fine materials pass through the screen mesh and collect in the lower hopper, while larger impurities and coarse materials are discharged from the drum's end. This continuous process ensures efficient material classification throughout operation.

• Rotary Screen Drum: Perforated mesh barrel designed for precise material grading
• Heavy-duty Support Frame: Sturdy painted bracket providing stable installation and operation
• Reducer & Driving Motor: Reliable power system ensuring continuous, stable rotation
• Multi-outlet Hopper: Efficiently separates materials of different particle sizes
• Protective Cover: Reduces dust spillover and enhances operational safety

Application Scenarios: Organic fertilizer production lines, compost plants, coal mining operations, solid waste recycling facilities, and agricultural waste processing plants.

Applicable Raw Materials: Organic fertilizer, livestock manure compost, coal, sludge, agricultural waste, and other solid materials with particle sizes less than 300mm.
