The FB-DRWF series double-deck rotor weigh feeder is a sophisticated piece of equipment designed for the precise measurement and feeding of powdery materials such as fly ash and mineral powder. Below is a detailed overview of its features, applications, and specifications:
The FB-DRWF series double-deck rotor weigh feeder integrates advanced rotor feeder technology with innovative design elements tailored for powdery materials. It comprises several key components:
Measuring Feeder Body: The main structure that houses the rotor and other components.
Double-Neck Rotors: A unique double-layer rotor design that enhances material handling and sealing.
Feeder Frame: Supports the entire feeder structure.
Support Device: Ensures stable operation of the feeder.
Speed Measuring Device: Monitors the rotational speed of the rotor.
Load Cell Measuring Device: Provides accurate weight measurement.
Control System: Manages and controls the feeder's operations.
Double-Layer Rotor Design:
Utilizes a stepped labyrinth structure to effectively lock materials and prevent air leakage.
Ensures complete sealing of pulverized material and gas, solving the material blanking issue associated with single-layer rotors.
Measurement Accuracy:
Achieves high accuracy of ±0.5%.
Large measurement area enhances the reliability of the measurements.
Environmental Benefits:
The feeder body is fully sealed, preventing dust from escaping and ensuring a cleaner working environment.
Long-Term Stability:
Maintains stable zero-point performance over extended periods.
Ease of Calibration:
Simple calibration process using hanging weights.
Flexible Installation:
Not limited by installation space constraints.
