FIELD: process engineering.
SUBSTANCE: invention relates to wasteless and resource-saving technologies in production of fibreboards and to non-polluting process of recovery and processing of timber wastes. Proposed method comprises mincing wood lumps, say, inactivated finer-bearing wastes of fibreboard production. Said wastes ate batched to layered dry grinding in clearance between rotor blades and stator counter blade with subsequent grinding, fibrillation and separation at fire grate to produce internally and externally fibrillated bond-forming fibre.
EFFECT: recovery of wastes in wasteless closed-cycle.
