A big bag discharger is equipment designed to facilitate the controlled unloading of solid materials (powders, granules, pellets, etc.) that are transported or stored in large industrial bags — the “big bags” or “bulk bags” (FIBC – Flexible Intermediate Bulk Container).

It serves to transfer the material from the big bag to a processing system, pneumatic conveying, hopper, conveyor belt, or feeder — ensuring:

• controlled flow
• dust sealing or containment
• operator safety
• minimization of losses / contamination
• compatibility with different big bag formats and weights

Typical applications include chemical, food, fertilizer, mining, plastics, construction, and ceramics industries, among others.

Operational safety and superior ergonomics
Agimix states that its equipment “reduces manual effort and minimizes the risk of accidents, protecting operators and facilities.”

• Less need for forklifts or intense manual handling of Big Bags (in some cases).
• Robust structure designed for industrial use, which tends to reduce mechanical failures and incidents.
• This is especially relevant for companies dealing with large volumes of Big Bags or materials that require safe handling conditions (powders, dust-generating substances, etc.).

Waste reduction
Agimix reports “controlled material flow, preventing product loss and ensuring process efficiency.”

• When the equipment has proper sealing, well-sized flow, and discharge control, there is less residual material in the bag or dispersed in the environment.
• This saving may not be huge for small volumes, but for operations with a high number of bags or expensive raw materials, it can represent a significant gain.

High productivity / integrated continuous flow
The equipment is promoted as “efficient integration with silos, mixers, and production lines, accelerating industrial processing.”

• In other words: less downtime, faster handling, and better integration with the production process.
• A well-designed Big Bag discharger helps avoid bottlenecks in the material feeding stage — which directly impacts process availability.

Robust and reliable construction
The company states that the equipment is built with carbon steel or stainless-steel structures, dust sealing systems, vibrators, and dosing valves.

• This choice of materials (stainless or carbon steel) allows it to withstand demanding industrial environments, including those with abrasion or aggressive materials.
• The robustness reduces maintenance or component replacement downtime, increasing plant reliability.

Flexibility and customization
Agimix states that “each Agimix discharger is adaptable to the specific needs of each client, supporting different types of Big Bags and materials.”

• This adaptability is a key advantage for operations handling various types of Big Bags (sizes, weights, shapes) or different materials (powders, granules, etc.).
• Optional accessories such as vibrators, screw feeders, and sealing systems can be added — allowing adjustment to the existing process.

Specialized technical support
The Agimix team guides the selection, installation, and maintenance of the equipment, ensuring continuous and trouble-free operation.

This support makes a difference, especially in facilities that require integration with existing systems or customization.

The presence of such support can reduce the risk of undersized or underutilized equipment — impacting return on investment.

Context for applying it to your operation

• If your plant operates with many Big Bags or frequent bag changes, a well-designed discharger quickly “pays back” through productivity and safety benefits.
• If the material is sensitive (food, chemical, pharmaceutical) or tends to generate dust or contamination, the sealing, hygiene, and robustness aspects become critical — making Agimix’s choice more relevant.
• If there is variation in bag size, weight, or material type, flexibility and pre-customization favor equipment that can adjust — and Agimix emphasizes this.
• However, it is always wise to compare: acquisition + installation + maintenance cost vs. the expected gains (less waste, fewer stoppages, greater safety, less labor) to assess the return on investment (ROI) in your specific case.

To ensure the safe operation of a Agimix Big Bag Unloader, it is important to follow best practices:

1. Operator Training
Ensure all operators are trained in the safe handling of Big Bags and the equipment, including emergency procedures.

2. Equipment Inspection Before Use
Check structural integrity, valves, supports, vibrators, and sealing systems. Any wear or damage must be corrected before operation.

3. Use of Personal Protective Equipment (PPE)
Safety glasses, gloves, dust masks, and safety footwear are essential to prevent accidents during handling.

4. Big Bag Verification
Check weight, dimensions, handle integrity, and bag closure before positioning it in the unloader.

5. Safe Positioning
Ensure the unloader is level and the surrounding area is free of obstacles or unauthorized personnel.

6. Flow Control
Adjust valves and dosing systems to avoid spills, blockages, or excessive discharge speed.

7. Avoid Overloading
Never exceed the maximum capacity of the equipment or the Big Bag as specified by the manufacturer.

8. Preventive Maintenance
Carry out periodic inspections, lubrication, and replacement of worn components according to the manufacturer’s manual.

9. Electrical Safety
Ensure all wiring and electrical components are protected, insulated, and properly grounded.

10. Emergency Procedures
Always have a plan available for spills, bag blockages, or mechanical failures, including rapid equipment shutdown.

To choose the ideal Agimix Big Bag Unloader, it is essential to consider various technical and operational factors that ensure efficiency, safety, and suitability for your production process. Agimix guides its clients to select the equipment based on the following criteria:
