Quantitative Feeder

Overview

The TDG series quantitative feeder is a high-tech product integrating conveying, weighing, and quantitative control. It can continuously, uniformly, and accurately perform dynamic metering, quantitative feeding, and continuous measurement of bulk, granular, and powdered materials. It forms a complete closed-loop control system with processors, actuators, and sensors. It is widely used in industrial fields such as building materials, cement, mining, coal, highways, metallurgy, chemicals, and electric power.

Key Technical Features

  • The drive unit uses a special motor for electronic scales, which is directly connected to the main shaft of the roller, eliminating the impact of mechanical vibration on metering.
  • An edge-integrated belt is adopted, greatly extending the service life.
  • A high-precision force parallel sensor is used, eliminating metering inaccuracies caused by uneven material distribution on the belt and longitudinal friction of the belt.
