Embodiment Construction

[0022] figure 1 A method 100 is shown for processing fibrous material, such as wood chips or wood pulp, i.e. cellulosic pulp used in the manufacture of fibrous products such as paper or board, in such a way that the fibrous material is refined , to facilitate pulping and / or chemical processing of fibrous materials.

[0023] Initiation step 102 includes: providing raw material for wood pulp; starting machines and equipment for producing, processing and moving wood pulp.

[0024] By using eg birch, spruce or pine as raw material, step 110 involves producing wood chips or wood pulp comprising wood fibers individually or in contact with each other.

[0025] In the case of so-called green tube pulp, in step 120 the wood pulp produced is transported to the paper and / or pulp mill, eg by pumping along purpose-built pipelines, directly into the refiner tanks to await refining. Alternatively, where the produced wood pulp is dried into bales for transport and / or storage, the dried bale...

Abstract

According to one exemplary embodiment, the application relates to a method (100) for processing a fiber material, comprising refining (130, 140) the fiber material, which is used in the manufacture of a fibrous product and which contains fibers, for promoting its pulping and / or chemical treatment. In the method, the fiber material refining (130) is conducted as compression refining performed by using a vibrating crusher.

Description

technical field [0001] The present application generally relates to a method for treating fibrous material. Background technique [0002] Fibrous pulp and chips are traditionally refined with blade refiners, which are used to separate and process the fibers to an optimum state from the point of view of the products made therefrom as well as the production process. Refining is a critical step in the manufacturing process for fiber products. Refining is usually accompanied by high energy consumption and a deterioration of certain properties of the fibers and products made from them, such as a reduction in fiber content, as well as dewatering, tear strength and paper thickness. Current refining technologies are still far from the theoretical optimum in terms of energy consumption and quality characteristics. [0003] Compression refining useful for fibrous materials has been the subject of several early studies on chemical pulp refining, and research related pilot machines ha...
