Beumer Group tackles dust emissions – Part two

Mobile loaders for bulk transporter vehicles

In the cement industry, high loading capacities are required. Stationary bulk loading heads are often not sufficient, especially if the bulk transporter vehicle is standing on a weighbridge and may not be moved during the loading process. It should be possible for the operator to move the bulk loading head to each filler neck of the vehicle. Depending on the properties of the materials to be loaded and the length of the vehicle, different sliding or swivelling loading system options are available. These mobile loading systems can be fitted with either one or two loading heads, depending on the space available.

First, the bulk material needs to be filled in bags so that it can be palletised, packaged and sent to the customer. The Group offers the BEUMER fillpac filling machine and provides equipment and systems for packaging lines. The new machine can be flexibly integrated with existing packaging lines and can be optimally adapted to the customer's situation. It includes specific weighing electronics to ensure the weight accuracy of the bags. Rejects caused by too high or too low filling weights can be nearly eliminated. The weighing unit communicates permanently with the filler neck via a specific software. The automatic bag weight adjustment determines the exact filling weight of the bags, thus enabling the exact degrees of filling during the filling process. The filling spout is equipped with a special hood that reduces dust emission to a minimum. There are also suction points on both sides in the area of the filling spout. The dust is sucked off directly where it builds up and fed back into the process. This allows for a practically dust-free filling of the bags. The three-position cylinder that regulates the coarse and fine flow is protected from dust, because it is positioned vertically and outside of the dirty area. The cylinder for bag discharging is also located in the dust-free zone above the filling spout.

The paper, PE or PP bags are then stacked on pallets of different sizes in a flexible, precise and stable way. For this, the company has developed the BEUMER paletpac^®, a high capacity layer palletiser. Bags have to be handled very carefully to avoid dust emissions. This is why BEUMER offers the palletiser with a clamp-type turning device or the newly developed twin-belt turning device. They position the filled bags quickly, ensuring their dimensional stability without any deformations. If required, BEUMER Group customer support can simply upgrade existing palletisers with the twin-belt turning device.
