Screw Feed Bagging Scale

Screw feeding scale for dosing and weighing of powders and fine granules

The screw feed bagging scale uses two motors to drive the screw for coarse and fine feeding, with a cut-off gate and frequency-controlled speed regulation. It is designed for powders and fine granular materials with moderate flowability, such as flour, milk powder, and powdered chemicals.

To maintain stable discharge, the outlet tube is equipped with a pneumatic vibration device to prevent bridging or adhesion, along with an adjustable air-return system to support clean, uninterrupted flow. A dust-extraction port is integrated into the system to improve workplace cleanliness and reduce airborne material during operation. The screw feeding scale uses a high-performance weighing controller and sensors to deliver a high level of automation. Coarse and fine feeding, bag clamping, and bag release are all managed automatically. The system can auto-tare and adjust errors during weighing, with adaptive optimization that fine-tunes control actions throughout the process. It provides gross weight, net weight, totalized weight, and bag count display, enabling automatic production data management. The controller can be connected to computers or printers for extended data integration.

1. Feeder type depends on capacity, material characteristics, accuracy and budget requirements:

• For small capacity and high fluidity materials, select screw feeder without hopper.
• For medium capacity and standard materials, select single hopper screw feeder.
• For large capacity, complex materials or high-accuracy applications, select double hopper screw feeder.

2. Maximum capacity values are based on packaging corn or corn flour under specified conditions.

• SMT technology ensures high reliability and stability, with EMC and RFI compliance.
• Stores up to 10 recipes, each with 9-digit accumulated weight and 6-digit bag count.
• Supports preset bag quantities and data exchange with upper-level control systems.
• Automatic zero-tracking, multiple delay-time settings, early-fill correction, and dynamic detection functions.
• Advanced anti-vibration filtering minimizes errors caused by mechanical vibration.
• Independent parameter storage for setup and calibration, with built-in parameter recovery.
