Filling Technology for the Building Industry
BEUMER fillpac

Cement, mortar, or gypsum - the bulk density, flow characteristics, and grain distribution of these products, which are filled in bags and packed for delivery to the customer, may vary significantly. BEUMER Group, a single-source provider of filling, palletizing, and packaging systems offers the fillpac, which can be flexibly integrated and adapted with existing packaging lines by the user. There are varying designs, depending on project requirements. Specific weighing electronics are utilized to ensure weight accuracy of the bags. Operators can nearly eliminate rejects caused by too high or too low filling weights.

Building materials have their own specific characteristics, such as high product temperatures or different volumes and weights - they may show an unusual flow behavior and may be dimensionally unstable. The fillpac enables material manufacturers to fill bags without any product loss. The systems of this construction series fill reliably, carefully, and sustainably while meeting the required throughput.

Precision Filling
The fillpac is equipped with a weighing unit that communicates permanently with the filler neck via dedicated software. The automatic bag weight control determines the exact filling weight while filling. This way the system always achieves accurate degrees of filling. Thus the packaging line works more efficiently as it is no longer necessary to remove under or overweight bags from the material flow. In addition, the quantity indicated on the bag always corresponds to the real volume.

Air Filling Machines for Pourable and Coarse-Grained Products
Depending on the requirements and on the material characteristics such as bulk density, flow behavior or grain distribution, BEUMER Group can offer both air and turbine filling machines from the construction series. The air filling machines are suitable for bagging pourable and coarse-grained products with particle sizes up to 10 mm. The systems use a blower to fluidize the materials in a pressure chamber. The products can then be filled into bags gently and precisely. Depending on the throughput, the user may opt for a rotary or an inline filling machine. The air rotary filling machines have four to 12 filling modules that are arranged in a circular pattern. Depending on the number of filling spouts, the systems reach a maximum capacity of 1200 to 3600 bags per hour for 25-kilo bags.

The air inline filling machines are generally equipped with one to four filling modules. Depending on the number of filling spouts positioned next to each other, the system achieves a capacity reaching between 300 and 1200 25-kg bags per hour. Regardless of whether the system is arranged in a circular pattern or in a line, capacity and utilization can be improved by installing an optional automatic bag placer. The filling process is carried out either automatically or at the push of a button. Two configurations are available for removing the bag at the end of the filling process: either manually or automatically with vertical bag discharge on a belt conveyor.

Turbine Filling Machine for Free-Flowing and Fine-Grain Products
The turbine process is the appropriate solution for companies which predominantly fill free-flowing and fine-grained materials, such as cement or gypsum. The turbine filling machines use motor-driven impellers. They can be arranged either horizontally or vertically, ensuring a particularly high filling pressure and, thus, a good compaction of the fine-grained materials to be bagged. The result is filled bags which are compact and dimensionally stable so that the user is no longer required to vent them.
