Background Introduction

In the fields of chemical engineering, building materials, agriculture, etc., woven bags and ton bags are widely used, but one-time consumption leads to a large amount of waste accumulation. These bags often adhere to pollutants such as oil stains and chemical residues, making recycling and cleaning a difficult task in the industry. This article analyzes the core challenges in the recycling process and introduces how automated equipment and processes can achieve efficient, low-cost, and environmentally friendly recycling treatment.

Three major difficulties in recycling and cleaning waste woven bags, ton bags, and belts:

Difficult to clean: Complex pollutants (oil stains, soil, chemical residues) penetrate and solidify into woven textures, making ordinary cleaning difficult to thoroughly clean and affecting the purity of recycled materials.

High cost: Traditional methods rely on manual sorting (low efficiency) and high-pressure water washing (high water consumption), resulting in high costs; Recycled materials with low purity and value are abandoned by enterprises.

High risk: open-air dumping of contaminated soil, burning and releasing toxic gases, forming a “use dispose pollution” cycle.

Core equipment

Automatic conveyor belt: The entire process of raw materials (waste bags) is automatically transported, reducing manual handling;
Crusher: The whole bag is broken into small pieces to improve subsequent cleaning efficiency;
Friction cleaning machine: high-strength friction to remove attached impurities such as labels and adhesives;
Rinse module (sedimentation/pressurization): sedimentation separates sediment, and pressurization flushes residual pollutants;
Spiral elevator: automatic connection between processes to achieve efficient material transportation;
Dehydration module (dehydrator/non plasticizing squeeze dryer): the core dehydration equipment that significantly reduces the moisture content of materials;
Pipeline drying system: The final dried material meets the moisture content requirements for recycling processing.

Mechanical advantages

Cleaning efficiency: The dual function of friction cleaning machine and forced pressure rinsing tank can achieve a material cleanliness of over 95%, completely separating labels, adhesives, and residual chemical substances;

Dehydration effect: 45kw extruder, with an hourly output of over 1000 kilograms and a material moisture content of ≤ 5%; After drying through the pipeline, the moisture content is further reduced to ≤ 3%, which can be directly used for regeneration processing;

Energy saving features: Adopting a water circulation system, it consumes less water for cleaning, has a high utilization rate of water resources, and reduces operating costs.
