RC-TL Series Variable Speed Quantitative Screw Weigh Feeder

Overview

The RC-TL Series Variable Speed Quantitative Screw Weigh Feeder is designed for continuous weighing, dosing, and feeding of powders and flowable bulk materials. It integrates metering and quantitative feeding in one system and is suitable for industrial processes that require stable flow control, sealed conveying, and continuous operation.

The equipment uses a screw conveyor driven by a motor and controlled through variable speed regulation. During operation, the control system compares the set value with the actual measured value and adjusts screw speed continuously to keep the feed rate within the required range. The series is especially suitable for fine powders and free-flowing materials.

Applications

• Building material dosing lines
• Chemical powder feeding systems
• Power plant additive feeding
• Metallurgy batching and proportioning lines
• Coal and coke related material dosing
