Product Overview

The TD4040 Loss-in-Weight Screw Feeder is a professional industrial automated dosing system designed for high-precision continuous or batch quantitative feeding. It is widely utilized in the chemical, pharmaceutical, food, plastic compounding, and lithium battery industries, specifically excelling at handling fine powders or granular materials that are prone to bridging or have poor flowability. By leveraging dynamic weighing technology, the system monitors real-time weight loss rates, allowing the PLC to precisely control screw speed for constant, accurate flow.

Core Advantages

• High-Precision Dosing Control: Equipped with industrial-grade high-sensitivity load cells, the system ensures a dosing accuracy of ±1% - 2% for strict consistency in mixture ratios.
• 304 Stainless Steel Construction: All material-contact parts are made from food/pharmaceutical grade S304 stainless steel, ensuring corrosion resistance, easy cleaning, and compliance with international hygiene standards.
• Active Agitation & Anti-Bridging: An integrated internal agitation mechanism forcefully eliminates "bridging" or "rat-holing," ensuring smooth feeding for even the stickiest or ultra-fine powders.
• Intelligent PLC Closed-Loop System: The system automatically adjusts variable frequency motor speed based on the target feeding rate without manual intervention.
• Modular Customization: Discharge heights and connection interfaces can be fully customized to match your existing reactors, mixers, or packaging machines.

Operation Process

1. Loading: Fill the 40L storage hopper with your material.
2. Setting: Configure the target feeding speed or batch weight on the PLC touch screen.
3. Monitoring: The PLC performs real-time loss-in-weight monitoring to calculate precise weight differences.
4. Dynamic Adjustment: The system automatically adjusts screw speed to maintain constant output, regardless of material density.
