Single Screw Plastic Pelletizing Line Description:

The single screw plastic pelletizing line is the main product of Purui Machinery. Engineers have gone through more than 20 years of research. The single screw plastic pelletizing machine has a firm structure, stable operation, and comfortable appearance and use.

Single Screw Plastic Pelletizing Line

The single screw plastic granulator has the characteristics of three types of equipment: crushing, extrusion and granulation. When recycling soft plastics (ie films, woven bags, packaging bags), it does not need to be crushed separately, and can be recycled and granulated directly.

Single Screw Plastic Pelletizing Machine Working Procedure:

Conveying feeding→metal detector → parallel twin screw extruder → bipolar vacuum exhaust system → hydralic screen exchanger → material outing mould → water tank → drying system → cutting granulating unit → storage hopper

Single Screw Plastic Pelletizing Machine Application:

Applicable plastic materials: PE, HDPE, LDPE, LLDPE, etc
Material shapes: film, bag, non woven fabric, (PE, PP) regrind
Material types: (rolls, loose, bundled),
Material comes from offcut, industry defective film and washed film.
Note: depending on different material properties, various downstream equipments are needed.

Single Screw Plastic Pelletizing Machine Detail:

  • Belt Conveyor
    As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.

  • Extruder
    A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content

  • Water-ring Die-face cutting system
    Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.

  • Vibration drying system
    Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
