This article will walk you through key considerations—from model selection and blade types to capacity and manufacturer reliability—ensuring you make a well-informed decision.
How To Choose The Right Plastic Crusher Machine Model
Identifying the material you intend to process and the desired output size is the foundational step in selecting a crusher. The market offers a variety of models tailored for different applications:
- Hard Plastic Waste: Machines designed for rigid materials like PET bottles or HDPE drums.
- Soft Plastic Waste: Crushers equipped to handle films, PP bags, and other flexible materials.
- Versatile Units: Some models can process both solid and hollow plastics efficiently.

For crushing PET bottles or HDPE drums, opt for a crusher with a suitable feeder sport diameter and a grinding chamber featuring a flat blade structure.

HDPE Drum
For softer materials like films or PP bags, a V-blade structure crusher is recommended for optimal performance.

PP Waste Bag
Specialized crushers are also available for specific shapes, such as pipes, ensuring efficient processing without compromising on output quality.

Understanding Crusher Blade Types
The type of blade is a critical factor that influences the crusher’s efficiency and suitability for different materials.
Lame a V

Ideal for PET bottles, PE films, leather, and large hollow plastics, V-shaped blades are commonly found in European standard heavy-duty crushers.
Sheet Blades

Fixed piece by piece to the rotor, sheet blades are versatile and suitable for a wide range of plastic wastes.
Lame a Piana

With an enhanced cutting angle, flat blades improve crushing efficiency, making them perfect for blow-molded parts and film products.
Scegliere il Materiale della Lame
Blade material determines durability and performance under different operational conditions:
- 9CrSi/Chrome Steel: Best for general plastics and engineering materials.
- SKD-11: Suitable for harder, thicker plastics and rubber blocks.
- SKH-9: Ideal for soft materials like foam, films, and fibers.

Determining Crusher Capacity
The crusher’s feed opening and chamber dimensions directly impact its capacity. Larger openings accommodate bigger material pieces, enhancing throughput. Below is a specification table for Rumtoo Macchina crushers:

| NC-C700 | 30HP/22KW | 710x460mm | 21 | 2 | 400-700kg | 1900x1400x1950mm | 1500kg |
| NC-C800 | 40HP/30KW | 810x460mm | 24 | 4 | 400-800kg | 2000x1500x2050mm | 1800kg |
| NC-C1000 | 60HP/45KW | 1020x650mm | 30 | 4 | 600-1200kg | 2300x1800x2400mm | 3000kg |
The Role of Screen Mesh in Output Size
The crusher’s screen mesh determines the size of the output flakes. Mesh number refers to the number of holes per square inch—a lower mesh number yields finer particles. Common sizes include 12mm, 16mm, and 20mm. Larger holes increase output but produce larger flakes, while smaller holes reduce throughput but yield finer material.

Importance of Motor Power Selection
Motor power, measured in kilowatts (kW), directly influences crushing output. Standard plastic crushers range from 15 kW to 160 kW. Selecting the appropriate power ensures operational efficiency and energy savings, aligning with your production requirements.

Efficient Flake Collection Methods
Post-crushing, flakes are typically conveyed to storage solutions. Options include containers, bags, boxes, or drums. For larger operations, silos with blowing functions facilitate easy retrieval and handling of material.
