Screw Weigh Feeder

The Screw Weigh Feeder is an integrated conveying and weighing system designed for the continuous feeding, accurate measurement, and flow control of powder and fine granular materials. The equipment combines screw conveying technology with a weighing system to ensure stable material delivery and reliable feeding performance.

The Screw Weigh Feeder is widely used in cement, chemical, mining, metallurgy, building materials, fertilizer, and other industries. It is suitable for handling materials such as cement powder, mineral powder, fly ash, pulverized coal, and other bulk materials.

Key Features

Continuous Weighing: Measures material flow during conveying and supports real-time monitoring of feeding rates.

Stable Feeding: The screw mechanism provides controlled and uniform material delivery.

Adjustable Feeding Capacity: A variable-frequency drive adjusts screw speed to meet different production requirements.

Reliable Construction: A robust structure and industrial drive components support continuous operation.

Automated Control: Can be integrated with PLC or DCS systems for automatic flow regulation and centralized production control.

Customized Design: Screw diameter, conveying length, feeding capacity, material contact parts, and control configurations can be customized according to operating conditions.

Working Principle

The material enters the screw feeder through the inlet and is transported by the rotating screw. The weighing system continuously measures the material load and calculates the feeding rate. Based on the measured flow and target value, the control system adjusts the screw speed to maintain the required material feed rate.

Applications

The Screw Weigh Feeder is suitable for continuous feeding and quantitative metering in cement production, mineral processing, chemical manufacturing, power plants, and other industrial processes. The system helps improve feeding stability, process control, and production efficiency.
