Ergonomic and efficient bigbag filling line
Robbe Industries has installed a bigbag filling line and 14 sampling stations at Valomet in Ghent, a subsidiary of waste processor Veolia. The custom systems contribute to the sustainable recovery of non-ferrous metals from bottom ash.
A bigbag filling line and 14 sampling stations were installed at Valomet in Ghent, a subsidiary of waste management company Veolia. The custom systems contribute to the sustainable recovery of non-ferrous metals from bottom ash. With more than 1,900 employees at 45 locations, Veolia deals with the waste and materials management of many tens of thousands of customers. One of the spearheads of the global concern is recovering valuable materials from waste. Veolia also recovers raw materials from the residual products of waste processing. For example, the bulk of bottom ash, left over after incinerating waste in power plants, is used to build roads or produce stackable building blocks
Non-ferrous metals However, the fine residual fraction of the processed bottom ash still contains aluminum, copper, lead and zinc. Veolia therefore developed a sustainable technology to also use these non-ferrous metals for the circular economy. The so-called Valomet process separates from the processed bottom ash a range of non-ferrous metals with a particle size of up to 20 mm and a purity of 75% to 95% (depending on the material). These products can be reused as new raw material in the metal industry through smelters and refineries. In 2015, Veolia launched a pilot plant that achieved a capacity of 1,300 tons of non-ferrous metals in one year.
Valomet factory
In 2018, Veolia built a new Valomet plant in Ghent with support from the Flemish government, which now has a capacity of 12,000 tons per year. It is the first European plant for the recovery of non-ferrous metals from bottom ash. This makes it an example of a zero-waste solution. Its location in the port of Ghent also means minimal logistical burden on the environment.
Bigbag filling line
Veolia strives for sustainability in its projects. The same applies to the packaging of non-ferrous metals. For the realization of a big-bag filling line and a series of sampling stations, Valomet turned to Robbe Industries. Two important parameters for this project were optimal ergonomics and maximum production capacity. A bigbag filling line with roller conveyor and two working positions was chosen, based on the “Apollo” design. This is a type of filling station in which a section of the roller conveyor is adjustable in height, eliminating the need for telescopic dump tubes.
Bordes
The operator works on a customized platform and can easily remove a bag from a pallet of empty big bags from that position. Next, the operator hangs the loops of the bigbag on hooks. In doing so, he leans forward, safely and comfortably supported by a co-springing parapet. For even more convenience, the rear hooks automatically move forward so that the loops are easy to hang from them as well. Then the operator pulls the filling hose of the big bag around the static dump tube. With the push of a button, the rear hooks move back and the trunk is clamped around the dump tube.
Filling process
The empty bigbag is automatically inflated by a fan prior to filling to ensure trouble-free filling. The non-ferrous metal is dosed into the hanging bigbag. While filling the big bag, a section of the roller conveyor – containing a pallet – moves upward to support the big bag and give it stability. Robbe Industries has developed a special helmet valve for precise dosing of the metal particles. This allows each bigbag to be perfectly filled by weight. After filling, the trunk is automatically disconnected and the section sinks back into the roller conveyor. The pallet with full bigbag then moves to the second working position, where the bigbag is closed and labeled. All weights and other process data from the bigbag-filling line are logged in a PLC linked to Veolia’s control system.
Sampling stations
Robbe Industries was also responsible for the design and construction of 14 sampling stations. These are small bigbag filling units that periodically collect samples of various types of materials from the production line. Given the low filling capacity, the big bags are manually hung in the sampling stations. The bigbag-filling line and sampling stations conform to all applicable norms and guidelines and also meet Veolia’s in-house standards
