POLYGON MACHINE
Polygonmachine PFDC Series Feeding Hopper and Dosing Belt Conveyors
Polygonmachine PFDC Series Feeding Hopper and Dosing Belt Conveyors
Polygonmachine PFDC Series Feeding Hopper and Dosing Belt Conveyors are designed to ensure continuous, precise, and controlled feeding of bulk materials in crushing, screening, and batching applications.
These systems deliver a steady material flow to crushers, screens, or mixers — optimizing performance, minimizing surges, and ensuring consistent product quality.

Key Features
High-Precision Dosing System:
Equipped with a variable-speed drive (VFD) for accurate control of belt speed and material flow rate, ensuring consistent feeding to downstream equipment.
Large-Capacity Feeding Hopper:
Reinforced steel hopper with abrasion-resistant liners prevents material buildup and ensures even distribution across the belt.
Heavy-Duty Belt Design:
Durable rubber or PVC belt material with high tensile strength resists wear, impact, and tearing under continuous loading conditions.
Integrated Weighing and Control System:
Optional load-cell-based weighing and feedback system enables real-time monitoring and automatic dosing adjustments.
Smooth and Continuous Feeding:
Belt tensioning and alignment mechanisms ensure uniform material flow without surging or blockage.
Energy-Efficient Operation:
Low-friction rollers and efficient drive units minimize power consumption during continuous operation.
Easy Maintenance and Accessibility:
Removable side covers, centralized lubrication, and easily replaceable components ensure minimal downtime.
Dust and Noise Control:
Fully covered or partially enclosed belt structures reduce dust emissions and operating noise.
