Tonne Bag Clamping Device

The tonne bag clamping device (also called a bulk bag clamp) is a heavy-duty system designed to secure and seal large flexible intermediate bulk containers (FIBCs, or “tonne bags”)—used for bulk material storage/transport (e.g., 500–1,000 kg loads of mining ore, agricultural fertilizers). It is typically a fixed or semi-portable unit with a robust clamping frame, hydraulic/pneumatic actuators, and seal plates. After filling the tonne bag (via a vibrating screen or conveyor), the device clamps the bag’s top opening (often folding the fabric first) to create a tight seal, preventing material spillage or contamination during transport.

Tonne Bag Clamping Device Introduction

 

The tonne bag clamping device (also called a bulk bag clamp) is a heavy-duty system designed to secure and seal large flexible intermediate bulk containers (FIBCs, or "tonne bags")-used for bulk material storage/transport (e.g., 500–1,000 kg loads of mining ore, agricultural fertilizers). It is typically a fixed or semi-portable unit with a robust clamping frame, hydraulic/pneumatic actuators, and seal plates. After filling the tonne bag (via a vibrating screen or conveyor), the device clamps the bag's top opening (often folding the fabric first) to create a tight seal, preventing material spillage or contamination during transport. It is integrated into large-scale packaging lines in industries like construction, chemicals, and agriculture.

 

Features

 

Heavy-Duty Sealing

Hydraulic/pneumatic actuators deliver high clamping force (up to 500 kg), ensuring a secure seal for large, heavy bags even with granular or powdery materials.

Automated Operation

Many models integrate with packaging line controls (e.g., sensor-triggered clamping) to reduce manual labor and ensure consistent sealing quality.

Bag Protection

Soft, non-abrasive seal plates prevent damage to the tonne bag's fabric, extending bag reuse potential (critical for cost-saving bulk transport).

Safety Features

Emergency stop buttons and interlock systems prevent operation when operators are near the clamping area, reducing workplace hazards.
