Optimized Heavy-Duty Screening Solutions for PT Trubaindo Coal Mining Operations
Addressing Critical Challenges in Coal Processing Efficiency
Operators at PT Trubaindo Coal Mining face three persistent challenges impacting productivity:
- Material Handling Bottlenecks: Up to 22% downtime occurs during peak processing due to undersized or worn screening equipment, costing an estimated $18,500 per hour in lost throughput.
- Premature Wear Costs: Standard polyurethane screens require replacement every 6-8 weeks in abrasive coal applications, generating $42,000 annually in spare parts and labor.
- Moisture Sensitivity: Conventional screens struggle with 18-25% moisture content, reducing separation efficiency by 30% during wet seasons.
Does your operation need screening solutions that withstand abrasive conditions while maintaining consistent throughput?
High-Capacity Trommel Screening System Overview
Equipment Type: Heavy-duty modular trommel screen (Model TTS-4500) specifically engineered for PT Trubaindo Coal Mining’s mid-sized particle separation requirements (50-150mm). 
Operational Workflow:
- Primary feed from crusher discharge conveyor
- Three-stage separation via adjustable drum segments
- Oversize material diversion to secondary processing
- Onboard fines collection system
- Radial stacker integration
Application Scope: .jpg)
- Ideal for ROM coal with up to 28% moisture content
- Maximum feed rate: 450 tonnes/hour
- Not recommended for particles below 20mm without optional fine mesh kits
