LDPE Film Pelletizing Machine

The LDPE film pelletizing machine consists of an extrusion system, a transmission system and a heating and cooling system.

LDPE Film Pelletizing Machine Structure:

The LDPE film pelletizing machine consists of an extrusion system, a transmission system and a heating and cooling system.

1. Extrusion system: The extrusion system includes screw, barrel, hopper, head, and die. The plastic is plasticized into a uniform melt through the extrusion system, and under the pressure established in the production process of the LDPE film pelletizer, screw continuous extruder head.

2. Transmission system: The function of the transmission system is to drive the screw and supply the rotation speed required by the screw in the extrusion process. It is usually composed of a motor, a reducer and a bearing.

3. Heating and cooling device: Heating and cooling are necessary conditions for the plastic extrusion process to be carried out.

LDPE Film Pelletizing Machine

The LDPE film pelletizing line has the characteristics of large output, low loss, low failure rate, easy operation and low cost. The LDPE film pelletizing line has a variety of heating methods. The heating method can be designed according to the customer’s electricity capacity and cost of the production area, and according to the customer’s materials and output, we can provide customers with high-quality and reasonable assembly lines.

LDPE Film Pelletizing 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
