PP Meltblown Nonwoven Recycling Equipment

A significant amount of melt-blown sheets are left over during production, so we developed this line to recycle the excess melt-blown sheets for reuse. The finished pellets can be used to make premium plastic bags and other polypropylene (PP) products.

Working Principle

Feeding: A belt conveyor is utilized to feed the material into the extruders.

Shredding and Compacting: The rotary blades of the compactor slice the incoming scraps. Frictional heating caused by high-speed rotary blades will heat and shrink the scraps just below their agglomerating point. An optimally designed guide structure compacts the material and directs it into the extruder screw. This crushes, dries, and compacts the material, enabling a fast and stable feed from the compactor directly into the extruder.

Plasticization and Degassing: A specialized single screw extruder is applied to gently melt the pre-compacted material. The plastic scraps will be thoroughly melted and plasticized in the first-stage extruder, and the plastic will be extruded by the second-stage extruder. With a double-zone vacuum degassing system, volatiles such as low molecular compounds and moisture will be efficiently removed, making it especially suitable for heavily printed film and material with some water content.

Melt Filtration: Segmented filtering principle, with pre-filtering in the first extruder and fine filtering in the second extruder, reduces the frequency of filter sieve changes. The requirements for the filter technology depend on the quality of the input material and the planned use of granules.

Pelletizing: A die-face water ring pelletizing system is set as the standard granulating method. An advanced dewatering vibration sieve combined with horizontal-type centrifugal dewatering produces high-performance dried pellets.
