FIELD: process engineering.
SUBSTANCE: wastes of adhesive multilayer sheets containing material to be glued, glue and anti-adhesive material are minced in multiple stages. Note here that glue adhesive properties are eliminated. Mincing is first made in precutting device and, then, in fine mincing device. Glue particles are used as friction-reducing additives. Minced material temperature at outlet of every processing stage is kept equal to 60°.
EFFECT: production of wood composite material by extrusion, moulding or forming.
