Big Bag Filling Machine
The optimal solution for loading bulk materials into tonne bags

Big Bag Filling Machine Overview
Big Bag Filling Machine (Tonne Bag Packing Machine) is an automated equipment for filling bulk materials into tonne bags. It is suitable for handling granules, powder and other large volume materials, and is widely used in building materials, chemical industry, agriculture, food and other industries.
Working Principle of Big Bag Filling Machine
Working Principle
Material Conveying
The material enters the hopper of the machine through a conveying system (e.g. screw conveyor or belt conveyor), ready to be filled into tonne bags.
Weighing and Filling
The material flow is controlled by a high-precision weighing system, and the bags are gradually filled according to the set weight to ensure that the weight of each bag is the same.
Bag mouth fixing
The operator hangs the mouth of the tonne bag on the clamping device and the machine automatically clamps and seals the mouth of the bag to prevent leakage during filling.
Whole Bag Handling
After filling, the equipment releases the clamping device and the tonne bags are automatically dropped onto the pallet or conveyed to the downstream system.

Features and Advantages of Big Bag Filling Machine
Features and Advantages
High efficiency
The equipment is suitable for rapid packaging of large volume materials, with a single bag filling weight of up to 500-2000kg, meeting the demand for high productivity.
Environmentally Friendly
The equipment is equipped with a dustproof system, which can control the spread of dust during the filling process and protect the operating environment.
High Precision
Built-in accurate weighing system can achieve ±0.5% weighing error to ensure the consistency of packaging quality.
Easy Operation
Designed with user-friendly operation interface, the bag opening is easy to fix and supports quick change of tonne bags to reduce downtime.

Frequently Asked Questions.
The equipment applies to a wide range of tonne bag sizes, adjustable height and clamping bag width, usually supports 500-2000kg tonne bags, the specific size can be customised.
The equipment is equipped with high-precision weighing system, and the weighing error is usually within ±0.5%, which is suitable for industries with high weight requirements.
Suitable for handling granules, powders or mixtures with good flowability, such as sand, gravel, cement, fertilisers, cereals and chemical raw materials.
The handling capacity depends on the material characteristics and tonne bag capacity, usually the equipment can complete the filling of 20-40 bags per hour.
The machine is highly automated, only manual hanging and starting of the bag is required, other steps such as weighing, filling and bag clamping are done automatically.
