FIELD: process engineering.
SUBSTANCE: invention relates to processing of plastics. Proposed method comprises preparation of initial material. Note here that, if required, said material is ground and fluidised, heated and continuously mixed at maintenance of lumpiness and looseness. Or, if required, it is degassed, softened and dried. Material viscosity is increased and/or material is crystallised. Prepared material is fused to allow the melt filtration for removal of impurities. Filtered melt is homogenised, degassed and discharged and/or processed. Processing can include pelletised and blown. Note here that said steps follow one after another in said sequence. Besides, this invention covers the plastic processing plant.
EFFECT: higher quality of finished products, better mechanical properties.
