Rotor Weigh Feeder

Product Introduction and Working Principle

1. Product Introduction

The Rotor Weigh Feeder is an industrial weighing and feeding system designed for the continuous measurement, metering, and controlled feeding of bulk materials. It combines a rotating rotor mechanism, a weighing system, a variable-speed drive, and an intelligent control unit to deliver a stable and adjustable material flow.

WEIFANG ZHITIAN provides Rotor Weigh Feeder solutions for cement plants, mining operations, chemical factories, power plants, and other industrial production lines. The equipment is suitable for handling various powdery and granular materials, including cement, mineral powder, pulverized coal, fly ash, limestone powder, and other dry bulk materials.

With a compact structure and automatic feeding control, the Rotor Weigh Feeder supports continuous production, accurate material proportioning, and reliable process operation. Feeding capacity, rotor configuration, motor power, and control system can be customized according to the material characteristics and application requirements.

2. Working Principle of Rotor Weigh Feeder

The Rotor Weigh Feeder operates through the coordinated action of material feeding, rotor rotation, weight measurement, and automatic speed regulation.

Step 1: Material Feeding

Bulk material enters the feeder from a hopper, silo, or upstream feeding device. The material flows into the rotor chambers through the inlet.

Step 2: Rotor Rotation and Material Transfer

Driven by a geared motor, the rotor rotates continuously and carries the material from the inlet to the discharge outlet. The rotor structure provides controlled material transfer and supports continuous feeding.

Step 3: Weight Measurement

The weighing mechanism detects the material load, while the control system processes the relevant weighing and operating signals to calculate the feeding rate and accumulated material quantity. In a gravimetric rotor weigh feeder, the material weight is measured directly rather than estimated solely from rotor speed.

Step 4: Automatic Flow Control

The controller compares the actual feeding rate with the preset target value and adjusts the rotor speed through the variable-frequency drive. When the material load or feeding conditions change, the system regulates the operating speed to maintain the required material flow.

Step 5: Continuous Discharge

The measured material is discharged continuously into the next production process, such as a cement kiln, grinding system, mixer, or conveying line.

This automatic process helps maintain stable material feeding and improves the consistency of industrial batching and proportioning operations.
