Stretch Film Granulation Line

The stretch film granulation machine manufactured by Purui Machinery is an automated granulation production line with high production efficiency.

Stretch Film Granulation Line Description:

Stretch film is often used as packaging film, which has high tensile strength, high elongation, good self-adhesiveness, and high transparency. The stretch film granulation machine manufactured by Purui Machinery is an automated granulation production line with high production efficiency.

Stretch Film Granulation Line

After the stretch film is crushed by the crusher, transported to the silo, and then transported by the conveyor belt at the bottom of the silo to the conveyor belt of the plastic granulator to be fed to the compactor.

The stretch film granulation machine adopts a double-column hydraulic screen changer and a vertical water ring pelletizing system. After pelletizing, the pellets are dewatered by a centrifugal dehydrator, and then connected to a vibrating screen and a silo to obtain dry plastic pellets.

Stretch Film Granulation 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

Stretch Film Granulation 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.

  • Compactor / Agglomerator
    The rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.

  • 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
