Fiberizing / Fiberizer / Refiner / Pressurized Refiner  

Area of Application:

The Pressurized Refiner is used for the preparation of chips into high quality flakes for MDF-board production and for the production of door leafs and insulting material. The Pressurized Refiner System has been built and continuously advanced for over 30 years. The result of this development is a Pressurized Refiner System that contains proven technology and modern solutions. Since 2007 the PALLMANN scope of supply has been complemented with the newly ECO ADVANCED® Refiner series. These systems are available as 58"-72" refiners and allow for an even higher efficiency in fiber production.
