MDF production

Efficient separation for consistently high board quality standards

Scheuch has been producing fibre sifters for the MDF board industry since the mid-1990s. These are able to adjust fractionation depending on the application's requirements, and can even be used for thin and extremely thin board production – and all with the high standard of sifter quality expected of Scheuch products.

Homogeneous fibre material is a particularly important requirement when it comes to producing high-quality standard and thin boards (MDF/HDF). The way to ensure this criterion can be met is to use a suitable sifter system with the right level of separation performance.

Fibre sifters: Crucial to board quality

In the final process stage before forming and the press, the fibre sifter plant plays an important role in ensuring that boards can be produced with a reliably high level of quality.

In this system, fibres are collected by an air flow directed upwards and to the side after they have been fed into the sifter casing. A second air flow from below counteracts the downward movement of the fibres and forms an air curtain. This means that only parts whose rate of descent is higher than that of the ascending air flow fall to the ground. These are from coarse materials that would have diminished the quality of the MDF boards during production. The fibres themselves – which have a low rate of descent – exit the sifter via the outlet opening, carried by the air flow.
