Spiral Crusher for Woven Bag

With the rapid growth of plastic packaging industries, large quantities of waste woven bags are generated every year. Recycling these woven bags has become an important environmental protection and resource recovery business. Among various recycling machines, the spiral crusher for woven bag recycling is considered one of the most efficient and practical crushing solutions.

Its special feeding and crushing structure makes it highly suitable for handling lightweight, flexible, and entangled woven bags that are difficult to process using traditional crushers.

What Is a Spiral Crusher?

A spiral crusher is a specially designed crushing machine equipped with a spiral feeding system and rotating crushing blades. It is mainly used for processing soft plastic materials such as:

• PP woven bags
• Jumbo bags
• Fertilizer bags
• Cement bags
• Ton bags
• Plastic films
• Agricultural woven fabrics

Unlike ordinary crushers, the spiral crusher continuously pushes lightweight plastic materials into the crushing chamber through a screw-type feeding structure, preventing material blockage and wrapping problems.

Why Is Spiral Crusher the Best Choice for Woven Bags?

Traditional crushers often face difficulties when processing woven bags because the materials are soft, lightweight, and easy to wrap around rotating shafts. Spiral crushers solve these problems efficiently.

Main Reasons:

• Continuous automatic feeding
• Prevents material bridging and clogging
• Strong anti-wrapping capability
• Stable crushing performance
• Suitable for high-volume woven bag recycling
• Lower labor requirements

The spiral feeding structure allows the machine to process loose woven bags smoothly without manual pushing.

Spiral Crusher Working Principle

The working process of a spiral crusher mainly includes the following steps:

Step 1: Material Feeding

Waste woven bags are loaded into the feeding hopper.

Step 2: Spiral Conveying

The internal spiral shaft continuously pushes the woven bags toward the crushing chamber.

Step 3: High-Speed Crushing

Rotating blades and fixed knives work together to cut and shred the woven bags into smaller plastic flakes.

Step 4: Screening Process

A screen controls the final output size to ensure uniform crushed materials.

Step 5: Material Discharge

Qualified crushed plastic flakes are discharged automatically for further washing or pelletizing.

The entire process operates continuously and efficiently.

Advantages of Spiral Crusher for Woven Bag Recycling

Modern spiral crushers offer many advantages in plastic recycling plants.

1. Excellent Feeding Performance

The spiral feeding system handles lightweight materials more effectively than traditional belt feeding systems.

2. High Crushing Efficiency

The machine can process large quantities of woven bags continuously.

3. Anti-Wrapping Design

Special blade and shaft structures reduce material entanglement.

4. Energy Saving

Optimized motor and cutting systems reduce electricity consumption.

5. Low Maintenance Cost

Strong machine structure and durable blades improve service life.

6. Wide Material Compatibility

Suitable for many soft plastic materials besides woven bags.

What Do the Final Crushed Materials Look Like?

After crushing, the woven bags become:

• Uniform plastic flakes
• Small shredded PP pieces
• Clean and manageable plastic fragments

The output size can usually be adjusted according to recycling requirements.

High-quality crushed materials are easier to wash, dry, and pelletize in later recycling stages.

Applications of Recycled Woven Bag Materials

The crushed and recycled PP woven bag materials can be reused in many industries.

Main Applications Include:

• Plastic granule production
• New woven bag manufacturing
• Plastic pipes
• Plastic pallets
• Injection molding products
• Agricultural plastic products
• Construction materials

After pelletizing, recycled PP materials can return to industrial production and reduce the consumption of virgin plastic raw materials.

Spiral Crusher in Complete Recycling Plant

A complete woven bag recycling line usually includes:

1. Spiral crusher
2. Friction washing machine
3. Floating washing tank
4. Dewatering machine
5. Drying system
6. Pelletizing machine

The spiral crusher serves as the key first-stage processing machine in the entire recycling system.

The spiral crusher for woven bag recycling is one of the most efficient machines for processing soft plastic waste. Its advanced spiral feeding system solves the common problems of material blockage and shaft wrapping found in traditional crushers. With high crushing efficiency, stable operation, and low maintenance cost, spiral crushers are becoming increasingly popular in modern woven bag recycling plants. Recycled woven bag materials can be reused in many industries, creating both environmental and economic benefits for plastic recycling businesses.
