HDPE Washing Line

1. Feeding & Size Reduction System

Delivers bulk woven bags directly into the size reduction system, where the material undergoes coarse and fine crushing, or is precisely shredded in one step, before entering the washing process.

Key Features:

Belt conveyor feeding system supports full-sized bales or large bundles without pre-treatment

Boxin-developed heavy-duty crushing chamber designed for tough woven bag structures

High-strength rotor shaft eliminates the need for pre-shredding

Produces uniform flake size, suitable for direct cleaning

Low maintenance frequency, engineered for continuous, stable operation

2. Hot Washing System

Provides intensive hot washing for heavily contaminated woven bags—especially those previously used for mineral powder, industrial sugar, or chemical packaging—ensuring thorough removal of stubborn residues.

Key Features:

Supports both alkaline and chemical washing solutions

Stable temperature control for optimized cleaning results

Especially suitable for input materials with chemical residues or oily contaminants

3. High-Speed Friction Washer

Effectively removes adhered powders, chemical residues, and surface contaminants from shredded woven bag flakes through intensive mechanical scrubbing.

Key Features:

Dual-stage friction design for enhanced cleaning intensity

Constructed with wear-resistant materials for long-term durability

Supports continuous high-speed operation without clogging or downtime

4. Sink-Float Separation Unit

Uses the difference in material density to separate plastic flakes from heavy impurities, such as residual filler or contaminants trapped inside woven bags.

Key Features:

Efficient removal of in-bag residues and heavy particles

Optional high-efficiency residue recovery system available to improve separation precision and reduce waste

5.Dewatering & Drying System

Efficiently reduces moisture content of processed woven bag flakes to below 5%, enabling faster packaging and ensuring consistent quality for downstream pelletizing.

Key Features:

High-speed centrifugal dewatering combined with hot air pipe drying

Delivers stable operation, even under high throughput

Prevents moisture-related quality issues in subsequent extrusion or granulation stages
