FIELD: process engineering.
SUBSTANCE: invention relates to crushing lignocellulose materials to fibers for production of structural, insulating and reinforcing materials and fillers. Lignocellulose materials with wet surface and mixed with fiber modifiers are subjected to controlled pressure of roller-dish grinder rolls of plane-matrix pelleting press. Note here that fiber modifiers penetrate deeply into said material to react therewith inside fibrous material pores stimulated by high moisture content. Minced and refined material is then extruded through holes drilled in plate dish matrix.
EFFECT: possibility to vary fiber thickness and length, intensified inner void volume compaction, hygroscopic property and adhesion.
