Description
The Continuous Loss-in-Weight Powder Feeder is used for accurate and continuous feeding of powder, granular and bulk solid materials. It is designed for production lines that require stable flow control, high feeding accuracy and reliable material handling performance.
Working Principle
The feeder monitors the weight change of the hopper in real time through a high-precision load cell. The control system calculates the actual feeding rate based on the weight reduction per unit time, compares it with the preset target flow, and adjusts the conveyor speed through PID closed-loop control. This ensures stable and accurate feeding during continuous operation.
Belt Conveyor Feeding Structure
The material is transferred to downstream equipment through a belt conveyor. The conveyor speed can be adjusted by the inverter according to material characteristics and production requirements. This structure helps maintain consistent feeding performance for different types of powders and granules.
Core Components
- Weighing System: Uses high-precision sensors to provide real-time weight feedback and support accurate flow control.
- Belt Conveyor: Adjustable belt speed helps match different material flow properties and feeding capacities.
- Control System: Integrated PID control supports automatic and manual operation modes.
- Sealed Hopper: Helps reduce dust leakage and improve the cleanliness of the working environment.
- Optional Agitation Device: Improves material flow for powders with poor fluidity or bridging risk.
- Modular Structure: Easy to clean, maintain and replace parts, reducing downtime in industrial production.
