The present invention relates to a method of producing a fibrous mass from peat. It has not been possible in the past to produce an easily dewaterable fibrous mass from peat when using in the production a continuous process which (1) could be carried out with a minimum amount of manpower, (2) enables a higher yield from the peat moors than had been the case before, (3) enables an efficient separation of colloids and particles smaller than 0.2 mm, and (4) dt enables the use of a simple equipment which, by a quickly made replacement of a screening member, can be changed to match the nature of the dug-up peat. The object of the present invention was to obviate this problem which, according to the invention, is realised substantially by the features that, after a primary sorting operation, the peat-material suspension is liquid-concentration regulated by supplying thereto an amount of liquid depending on the degree of humification of the dug-up peat, and then supplying the suspension under pressure to at least one screening member having a permeability depending on the peat-fibre concentration of the peat-material after said concentration regulation. |
