Engineering Recommendations
Wear Protection
Abrasion-resistant liners at lower chute impact section, material acceleration zone, and conveyor loading point.
Maintenance Access
Inspection doors at the impact region and direction-change sections to simplify routine service.
Dust Control
Proper skirt sealing around the loading zone to contain fine coal particles and reduce dust emission.
Future Optimisation
If throughput is increased, additional DEM verification recommended to reassess impact forces, belt loading profile, and wear rates.
Conclusion
The DEM simulation confirms that the transfer chute design performs effectively under the specified operating conditions. Coal flows smoothly from the vibrating feeder to Conveyor CV101/CV201 with controlled velocity, stable material trajectory, and centralized belt loading.
No significant flow restrictions or blockage tendencies were observed. The design is suitable for reliable industrial operation, with localized wear protection recommended at the chute impact zone to maximize service life and reduce maintenance requirements.
