BIG-BAG Filling and Emptying

Big-Bag, also known as FIBC (Flexible Intermediate Bulk Containers), are flexible containers designed for transporting and storing bulk materials.

They are usually made of durable polypropylene fabric, which provides high load capacity – up to 2000 kg. These bags come in various versions: with a filling and discharge spout, with a closed or open top, as well as with additional plastic inserts for moisture protection.

Companies use these bags in various industries. Their main advantage is ease of transport and storage – they can be moved using forklifts or overhead cranes. When empty, they take up little space, which reduces logistics costs. Big Bags enable safe storage of materials in harsh environmental conditions. They protect the product from contamination and mechanical damage. They are also an environmentally friendly solution as they can be reused or recycled.

The basic equipment of the station includes a height-adjustable support frame, a filling head with a seal, and a scale. Depending on your needs, the stations can be equipped with vibrating compactors for material compaction, bag inflation (preforming) systems prior to filling, bag tensioning and lifting systems, automatic bag closing systems, and other functions.

Our stations are most often equipped with filling heads with inflatable seals, which allow for a tight connection of the bags. This prevents dusting and material loss and ensures safety in Ex zones. The integrated weighing system precisely controls the filling level and eliminates the risk of overfilling.

BSA stations can be fed by gravity, a dosing device, a screw conveyor, or a pneumatic system. The use of the station improves ergonomics and operator safety. The automated process minimizes filling time and increases production efficiency. The bags are filled stably, which facilitates their subsequent storage and transport. BSA loading stations are a modern solution supporting clean and efficient packaging processes.

Typical equipment includes a support frame, a bag lifting mechanism (e.g., chain hoists on a crane), and an unloading assistance system in the form of special massagers or vibrators. The stations have connections to devices for further transport or dosing of material, e.g., a dosing unit, screw conveyor, or pneumatic system. A dust extraction system and a docking unit are also often used, which tightly secures the bag spout, preventing dusting and contact with the environment.

BSB unloading stations improve work safety and hygiene in the production process. They also facilitate the handling of large quantities of raw materials with minimal operator involvement. The devices are adapted to the specific characteristics of the material, e.g., sticky, dusty, or heavy. Their use increases production efficiency and reduces the risk of product failure or contamination.
