La Linière du Ressault wanted to establish its own fax plant with innovative and efficient production methods that promote employee well-being. The challenge was to design a system that effectively removes dust and separates material flows to achieve a better quality end product.
Together with Keller Lufttechnik and Depoortere, Lybover designed a customised turnkey solution. This included a detailed analysis of emission points, the use of CFD simulations and ventilation models, and the design of energy-efficient systems with simple maintenance options.
The project was successfully completed, with measurement results complying with limit values, and future expansions were taken into account. A second line is in preparation.
In 2025, Lybover will celebrate its 40thanniversary. Founded in 1985 as Keller Lufttechnik Benelux by Luc Boels, father of the current CEOs, Lybover quickly developed expertise in dust collection and material transport in the flax industry. Over the years, Lybover has evolved from a simple distributor of dust collectors to a technology expert, offering complete solutions, from conceptual engineering to practical implementation and after-sales service. Lybover’s priority has always been to simplify its customers’ tasks as much as possible by offering them customised, durable solutions.
This expertise in the flax industry has been strengthened through cooperation with Keller Lufttechnik GmbH, a German technology partner, and Depoortere, Belgium’s leading supplier of flax harvesting and scutching equipment. The intensive collaboration with these two partners is still based on a shared vision and DNA, putting the customer at the centre of our concerns.
A new line for La Linière du Ressault
Founded in 1919 in Le Neubourg, La Linière du Ressault specialises in combing linen. The company had plans to set up its own linen scutching plant. Jean-Louis Maurice, its CEO, was motivated by the vision of innovating while creating an efficient production environment conducive to staff well-being. It was against this backdrop that Depoortere offered La Linière du Ressault a turnkey project to build its production facilities.
Depoortere has teamed up with Lybover to supply the dedusting and material transport systems, with Studys for the co-product treatment and with Elec3p for the electrical and control systems. Three experts in their respective fields who have joined forces to carry out this turnkey project with Depoortere.
Thanks to its in-depth expertise, Lybover carried out its demanding assignment with remarkable precision. The assignment included dust abatement from machines and workstations as well as pneumatic transport.
Compact and energy-efficient design
Lybover understands that flax is an agricultural product in which all the elements can be used, from the seed to the stones that unexpectedly find their way into the process during harvesting. By separating these different material flows, we can achieve a better-quality end product in the production chain, which goes beyond simply removing dust and transporting material.
Lybover analysed, advised on and installed the dust extraction units for the production facilities. In the first phase, emission points were mapped and the best ventilation technique for each part of the line was determined using proven ventilation models and CFD simulation. The appropriate flow rates were determined with a view to providing a compact, simple and energy-efficient installation. Optimum ease of maintenance was also taken into account in the design.
In the cellar, a specific dust extraction system was installed, optimised to minimise pressure losses and increase the efficiency of extraction from the scutching drums. This allows the use of smaller, lighter sections of ducting, simplifying assembly and maintenance while providing substantial clearance between the floor and the pipework. Inspection and cleaning hatches have also been installed to facilitate operation and ensure an easy-to-clean workspace.
Smart optimisations make the difference
Operators can now work on the scutching machine’s shredder and regulation table areas in a dust-free environment for their maintenance and production operations. When the scutching machine doors are opened, a by-pass system is automatically activated to create localised over-ventilation, enabling the inside of the area to be cleaned with compressed air, without polluting the rest of the plant.
All pipework has been tailor-made to suit the purpose, potential wear and tear, technical constraints, air flow velocity and flow rates required. Each circuit is colour-coded, providing a clear overview of the piping circuits and facilitating communication between the maintenance team, operators and Lybover’s after-sales service team.
Second line in preparation
La Linière du Ressault has reaffirmed its confidence in Depoortere, and therefore in Lybover, for the subsequent integration of a second scutching line. When the first scutching line was designed, this possible extension had already been taken into account in the sizing of the equipment and machinery. Lybover will supply another dust collector.
