Product Description

Industrial Plastic Claw Crusher | 250–1050 kg/h

The Vertical Claw Blade Crusher is an industrial plastic crushing machine specially designed for processing small pieces of machine head material, hard plastic lumps, and other suitable rigid plastic waste.


Unlike conventional plastic crushers that use standard flat cutting blades, this machine adopts a claw-type blade structure. The rotating claw blades work together with fixed blades to cut and break hard plastic materials into smaller fragments, making them easier to collect and process in subsequent recycling operations.


Chenxing Machinery offers seven configurations in the  Series, including three-claw and five-claw blade designs. With motor power ranging from 18.5 kW to 90 kW and production capacities from 250 kg/h to 1050 kg/h, the series provides different crushing solutions for plastic manufacturing facilities and recycling plants.


According to the supplied specifications, the crusher is designed to process hard plastic materials into approximately 5–20 mm fragments. The screen size is specified at 12–16 mm, with customized options available according to processing requirements.


Whether you need to recycle machine head material from plastic extrusion production, hard plastic production scrap, or other suitable rigid plastic waste, the  Vertical Claw Blade Crusher provides a dedicated size-reduction solution.

1. What Is a Vertical Claw Blade Crusher?

A Vertical Claw Blade Crusher, also known as a Plastic Claw Crusher or Hard Plastic Crusher, is a mechanical size-reduction machine designed for crushing rigid plastic materials.

It uses a rotating claw blade assembly installed inside the crushing chamber. As the blade shaft rotates, the moving claws interact with fixed blades to generate cutting and shearing forces.

This structure helps break hard plastic pieces into smaller fragments through repeated cutting action.

Compared with ordinary flat-blade crushing configurations, claw-type blade arrangements are particularly suitable for certain hard plastic materials and small pieces of machine head waste.

The crushed material can then be collected for further recycling, washing, extrusion, or pelletizing, depending on its material characteristics and quality requirements.



2. Main Applications of Vertical Claw Blade Crusher

The  Series is primarily designed for small pieces of machine head material, especially hard plastic waste.

Typical applications include:

Machine Head Material Recycling

Plastic machine head material generated during extrusion production can be collected and crushed into smaller pieces for subsequent material recovery.


Hard Plastic Scrap Crushing

The claw blade structure is suitable for processing appropriate rigid plastic scraps and small plastic lumps.


Plastic Production Waste Recycling

Rejected hard plastic products, production offcuts, and suitable manufacturing waste can be reduced in size before being returned to a recycling or reprocessing system.


Plastic Recycling Plant Applications

The machine can be used as a crushing stage in a plastic recycling process, preparing suitable hard plastic materials for subsequent washing, drying, or extrusion.


Typical Materials

Depending on material dimensions and machine configuration, potential applications include:

  • Plastic extrusion machine head waste

  • Hard plastic lumps

  • Rigid plastic production scrap

  • Suitable injection molding waste

  • Hard plastic rejected products

  • Other suitable rigid plastic processing waste

Material compatibility should be confirmed before ordering. Large, flexible, reinforced, or unusually thick materials may require a different crushing configuration or preliminary size reduction.

3. Working Principle of the Vertical Claw Blade Crusher

The  Series operates through mechanical cutting and shearing between rotating claw blades and fixed blades.

The electric motor drives the blade shaft, causing the rotating claw blades to move inside the crushing chamber. When hard plastic material enters the chamber, the moving blades interact with the fixed blades to break it into smaller fragments.

Crushing Process

Step 1: Material Feeding

Small pieces of machine head material or other suitable hard plastic scrap are fed into the crushing chamber through the feeding opening.


Step 2: Claw Blade Engagement

The rotating claw blades engage with the incoming material and apply cutting and shearing forces.


Step 3: Fixed Blade Cutting

The fixed blades work together with the rotating blades to further break down the plastic material.


Step 4: Repeated Size Reduction

The material undergoes repeated cutting inside the crushing chamber until it reaches a size suitable for passing through the screen.


Step 5: Material Discharge

The crushed plastic fragments pass through the screen and are discharged for collection and subsequent recycling.

The final particle size depends on the screen opening, material characteristics, blade condition, and operating conditions.
