Introduction
Rotor Quantitative Feeding Scale
Rotor Quantitative Feeding Scale
High-Accuracy Continuous Weighing and Feeding System for Cement, Fly Ash and Powder Materials
Precise Gravimetric Feeding Solution for Powder Materials
Unlike conventional volumetric feeders, the rotor scale continuously measures actual material weight during operation and automatically adjusts the feeding rate according to process requirements, ensuring precise material dosing and stable production performance.
The fully enclosed structure provides excellent sealing performance while minimizing dust emissions and material loss. This makes the system particularly suitable for cement powder, fly ash, slag powder, coal powder, mineral powder, and other fine bulk materials requiring accurate continuous feeding.
Rotor quantitative feeding scales are widely used in cement plants, power stations, mining operations, steel mills, chemical industries, and bulk material handling systems where stable flow control and high weighing accuracy are essential.
Key Features & Advantages
High Feeding Accuracy
Continuous gravimetric weighing measures actual material weight instead of estimated volume, ensuring superior dosing precision.
Stable Material Flow
Provides uniform feeding, continuous discharge, and effectively prevents arching, bridging, and plugging of powder materials.
Dust-Free Operation
Fully enclosed structure minimizes dust emissions and material loss while maintaining a clean production environment.
Ring-Balance Weighing System
Advanced weighing structure isolates external disturbances and improves measurement stability and accuracy.
Minimal Impact Interference
Feeding point, discharge point, and weighing fulcrum share the same axis, reducing weighing errors caused by material impact.
Wide Flow Control Range
Suitable for both low-flow and high-flow applications while maintaining consistent feeding performance.
PLC & DCS Integration
Supports PLC, DCS, SCADA, Industrial Ethernet, and Modbus communication for modern factory automation.
Low Maintenance
Wear-resistant components and a simplified mechanical structure provide long service life with reduced maintenance costs.
Working Principle
Rotor Feeder
Bulk powder enters through the rotor feeder, which delivers material uniformly into the weighing chamber.
Rotor Weighing Scale
The rotating impeller transports material evenly from inlet to outlet while generating measurable weight differences.
Weighing System
Load cells continuously measure material weight while speed sensors monitor rotor rotation for flow calculations.
Intelligent Control Unit
Automatically calculates flow rate and adjusts feeder speed to maintain the desired material throughput.
Main Components
Powder Quantitative Feeder
Provides stable and continuous feeding of powder materials into the weighing system.
Rotor Weighing Unit
Performs material conveying and real-time gravimetric weighing simultaneously.
Air Locking Device
Maintains system sealing and prevents air leakage during material transportation.
Load Cell System
High-precision sensors continuously monitor material weight and feeding accuracy.
Speed Measurement System
Monitors rotor speed and provides real-time data for flow rate calculation.
Intelligent Control Cabinet
Provides automatic feeding regulation, process monitoring, and production data management.
