Trommel Screen
Rotary screening machine that efficiently separates materials by size through a rotating cylindrical drum with perforated screens, ideal for composting, MSW sorting, material recovery, and size classification applications.
Overview
Rotary Screening Technology
Cylindrical rotating drum with perforated screens efficiently separates materials by size as they tumble through the machine, ensuring accurate classification and sorting.
Multiple Screen Options
Available with various screen sizes and configurations to accommodate different material types and sorting requirements, from fine compost screening to coarse MSW separation.
High Processing Capacity
Large diameter drum design with optimal length and rotational speed provides high throughput while maintaining excellent separation efficiency across various materials.
Key Benefits
Effective Separation
Achieves precise size-based separation of mixed materials with high accuracy rates.
Gentle Material Handling
Tumbling action minimizes material damage while ensuring thorough screening.
Versatile Applications
Suitable for composting, MSW sorting, material recovery, and various screening needs.
Reduced Contamination
Effective separation improves downstream processing and material purity.
Low Maintenance
Simple rotating design with minimal moving parts reduces maintenance requirements.
Weather Resistant
Durable construction suitable for both indoor and outdoor installation.
Operating Principle
• Materials smaller than screen openings fall through
• Larger materials continue to the discharge end
• Multiple screen sections allow staged separation
• Adjustable speed controls residence time and efficiency
Fine Screening:
• 10-20mm openings for compost finishing and fine material recovery
Medium Screening:
• 30-80mm openings for general MSW sorting and separation
Coarse Screening:
• 100-200mm openings for large object removal and pre-sorting
Multi-Deck:
• Multiple screen sections for staged separation and classification
Application Examples
Composting Operations
Screen finished compost to remove oversized materials and contaminants, producing uniform, market-ready product that meets quality specifications.
Municipal Solid Waste
Separate MSW by size for improved recovery of recyclables and removal of contaminants, enhancing overall facility efficiency and material quality.
C&D Waste Processing
Sort construction and demolition debris by size, separating valuable materials for recovery and removing fines and contaminants from the waste stream.
Material Recovery Facilities
Pre-sort incoming materials by size, improving downstream sorting efficiency and increasing recovery rates of valuable recyclable commodities.
