The PP woven bag recycling line is designed for processing various types of PP woven bags such as rice bags, cement bags, and more. The complete process includes shredding, water rinsing, friction washing, drying through the washing system, as well as compacting, plasticization, pelletizing, and drying through the pelletizing system. The PLC intelligent system enables high automation, reducing the need for manual operation to only 3-4 operators. With over 20 years of experience in recycling, Gangsu has not only mastered the key technologies but also enhanced machine designs to cater to specific product characteristics. Gangsu provides PP woven bag recycling solutions that offer high output and low energy consumption.

APPLICABLE MATERIALS

BRIEF DESCRIPTION

  • This line is suitable for various films and woven bags with high sand content of up to 80%
  • It utilizes recycled water to ensure cleaning effectiveness while controlling water flow and evaporation.
  • Core components of the pre-processing module are designed to be wear-resistant, ensuring long-term continuous operation of the system.
  • Efficient pre-shredding and pre-washing system removes a majority of impurities, such as sand, protecting subsequent equipment and significantly extending the lifespan of the fine crushing and cleaning system.
  • Fine crushing system designed for uniform size distribution of shredded films, facilitating easy cleaning.
  • High-speed centrifugal cleaning system applies appropriate blade impact force at suitable rotational speeds to achieve excellent cleaning results for different materials.
  • Cleaning tank drum designed for underwater high-pressure cleaning, maximizing the removal of residual impurities; claw-type uniform discharge ensures smooth material outflow.
  • Uniform control of moisture content provides the foundation for the dehydration module.
  • Combination of centrifugal dehydration, screw squeezing, and high-temperature hot air drying ensures that the moisture content of the final product is strictly controlled within 5%, suitable for high-quality pelletization requirements.
  • Fully automated control of the entire line, interconnected operation between system units, maximizes production capacity while having predictive capabilities for potential abnormal situations, ensuring system safety to a great extent.

WORKING PROCESS

UNIT INTRODUCTION

Belt Conveyor

Used for conveying material, the surface of the belt is equipped with anti-slip devices and the height is adjustable.

Crusher

To crush the raw material into smaller pieces with water added during the process. The blade material is SK11.

Friction Washer

The high-speed rotating screw makes the material to be thoroughly scrubbed with water, effectively washing away its impurities.

Floating Washer

Used for separating sand, pulp, and other impurities from the raw materials. The main material used is stainless steel.

Dehydrator

High-speed centrifugal dehydration to remove moisture from the material and simultaneously eliminate residual impurities.

Squeezer

The material is squeezed and partially plasticizing through the screw compress, allowing for direct pelletizing with higher output.

Hot air dryer

For drying the material through hot air pipeline, which is also insulated with thermal insulation material to reduce energy consumption loss.

Control Cabinet

For control the operation of the entire line. Electrical components adopts famous brands such as ABB, Siemens, Omron, Schneider etc.
