Top 3 Guidelines for Choosing a Plastic Crusher

When selecting a plastic crusher, it's crucial to consider its efficiency and durability. The right choice can significantly impact the performance of the crushing process and the lifespan of the machinery. To assist you in making an informed decision, here are three essential guidelines to follow:

1. Selecting the Appropriate Knife Type

Claw Cutter Design
The claw-type blades are highly effective for crushing and recycling diverse plastics, particularly for larger or tougher plastics, such as injection lumps and shoe lasts. For materials like PVCPETABSPPPEPCPMMAPAPS, claw-type plastic granulators are highly recommended.

Flake Cutter Design
For general plastics, such as sheets, tubes, profiles, and packaging materials, flake-type blades excel. They are ideal for products like PVCPPPCPS and other related plastics.

Flat Cutter Design
Flat-type blades work well for recycling lighter items like boxes, thin pipes, blow-molded components, plastic bottles, and remnants from nozzles. They are particularly suitable for PE and PET products.

V Type Cutter Design
V-type blades are well-suited for recycling hollow products, leather, films, and other various types of plastics.

2. How to Choose the Right Model

Based on Crushed Product Size
To ensure optimal performance, the material being crushed should fit into the crusher's chamber. For thicker or harder items, consider models featuring one or two motor levels, matched with output requirements.

Based on Grinding Chamber Size
It’s vital that the defective products or nozzles being crushed do not exceed the grinding chamber's dimensions. If you need to crush longer materials, such as trays or pipes, an inclined plastic crusher is advisable for direct crushing without cutting.

Based on Production Needs
Different models of plastic crushers have varying grinding capacities. For customers with high-volume crushing requirements, select a model aligned with the granulator's output while ensuring that the products fit into the crusher. The specifications should be checked to identify the output for various materials, as crushing mineral water bottles or film products might yield only about a third of the quoted minimum output.

Based on Application Scenarios
Different crushers are best suited for various scenarios. For instance, if you're looking for centralized crushing and recycling, standard plastic crushers should be selected based on the desired output and material type. For in-situ recycling alongside machinery, beside-the-press granulators can be optimal. Moreover, online plastic crushers equipped with extraction features can significantly lower labor costs while automatically recovering and recycling materials.

3. Choosing the Right Blade Material
