Energy efficiency is strongly dependent on the careful choice of the installed solutions, i.e. devices small and big that do not necessarily influence the paper mill production process and yet make it possible for it to achieve major energy savings. Officine Airaghi S.r.l. concentrated all its efforts exactly on this and focused on energy saving with the aim of presenting its customers with tangible results obtained thanks to innovative technologies.
Efficiency in the front line
As Michele Ghibellini of Officine Airaghi explains: “After times of crisis new opportunities are discovered and what one already has is used in a more rational way. It is therefore necessary to understand what variables within a paper mill are often not considered, which can immediately help optimize the paper mill work and production system. Only then is it possible to further rationalize energy savings and productivity”.
The «hot» points of the process
The first step towards energy efficiency lies in identifying those steps in the paper making process that can be improved; one of them is stock preparation. “Energy consumption in this area makes up for about 30% of the total energy consumed in the paper mill”, says Mr. Ghibellini.
“A minor modification at this stage of production can lead to major changes at the level of the final product, that is why there has always been some hesitation in changing the machines working parameters. However, an increasingly strong interest is currently being shown for refiners and deflakers.
As far as we are concerned we have shown how it is possible to optimize, through the use of our non conventional products like EFP® and CNConic®, those machines and installations that are oversize compared to actual needs or conversely up to their use limit with traditional spare parts.
We therefore aim at providing technical support in the stock preparation to plan and produce tailor-made fillings enabling our customers to reach the ideal value, which perfectly combines refining results with the energy and maintenance costs”.
