Plastic recycling grinders serve as essential tools in any plastics manufacturing facility. These machines facilitate the reclamation of raw materials from production waste or defective items created from processes such as injection molding, thermoforming, or extrusion. By opting for the right grinders, companies can independently reclaim valuable raw materials and reintegrate them into the production cycle. Adopting the circular economy model not only leads to tangible cost savings but also helps minimize the carbon footprint, thereby reducing adverse effects on the environment.

To effectively choose a mill that aligns with your specific needs, several crucial aspects must be considered. It’s important to recognize that incorrect shredding techniques, which may cause excessive heating, can lead to material degradation, making it unsuitable for subsequent processing stages. A well-selected grinder ensures high-quality grinding free from dust, operates efficiently, has a long service life, and quickly pays for itself.

1. Match the Grinder to the Intended Material and Destination

There are two main types of grinders based on the material that needs to be ground:

1. Roller mills, like those offered by the French company MO.DI.TEC, are ideal for hard materials such as ABS, PA, PEEK, and PEAK. These bench mills are specifically designed for recycling purposes directly alongside injection molding machines. The broad selection from the manufacturer allows the device to be customized to the type and size of the items being processed.

Roller mills use a slow-running technology, providing numerous benefits such as low noise levels and absence of dust in the ground material. This grinding approach ensures high-quality regrind without material degradation, allowing the reclaimed raw materials to be directly reintegrated into production for the creation of additional high-value products.

2. Knife Mills: A Different Approach

The second type of grinder consists of knife mills, produced by the German company Neue Herbold, which are engineered for shredding soft materials like polyethylene, polypropylene, LDPE, and elastomers such as TPE, TPU, and TPV. The swift rotation of the knives in these machines allows for better shredding of softer textures.

Advantages of the Neue Herbold knife mills include:

• High processing capacity due to optimal geometry of cutting elements
• Low energy consumption while maintaining superior efficiency
• Minimal dust production
• Knives positioned at an angle to create a scissor-like cutting effect
• Quick and straightforward knife replacement; rotor and stator adjustments can be made outside the grinder, enhancing operator safety and minimizing downtime.

3. Choosing the Right Grinder for Specific Industries

Understanding how the type of material impacts the industry is essential. In sectors like automotive and technical manufacturing, slow-speed mills such as those by MO.DI.TEC are the preferred choice. These solutions currently dominate the automotive manufacturer market. Conversely, in the household appliance sector, characterized by significant use of ABS and hard polyethylene, slow-speed roller mills are recommended.

4. Key Considerations When Selecting a Grinder

• Grinder Price:

Investing in a durable and reliable grinder with a lengthy service life is crucial. While high-quality plastic grinders may have a higher initial cost, they guarantee a return on investment and lower operational costs over time. Proven brands such as MO.DI.TEC and Neue Herbold are known for their longevity and efficiency.

• Power Consumption

Roller mills, such as those by MO.DI.TEC, consume minimal power, featuring motors ranging from 0.75 kW to 2.2 kW, with low rotational speeds of about 25 rpm.

• Operating Costs

Roller mills also boast multi-fold advantages, as their cutting elements have significantly longer lifespans between sharpening compared to knife mills, which require more frequent maintenance.

• Work Comfort and Dust Levels

Roller grinders operate much quieter than knife grinders and generate no dust, enhancing the overall work environment.

5. Assessing Capacity and Size

It's important to determine the dimensions and required quantities of material for shredding. Overloading a plastic shredder can result in suboptimal performance and safety hazards. Be mindful that there is a limit to how small a load can be to maintain efficiency.

For those who plan to process varying load sizes, make sure your plastic grinder can adjust accordingly. If flexibility is lacking, consider resizing the larger loads or selecting a medium-sized shredder that can accommodate both small and large tasks.

For unique requirements, direct conversations with the manufacturer can ensure the machine's specifications are appropriate for your needs.

6. Define Desired Output Characteristics

It’s imperative to clarify what role the shredder will serve before making any purchase decisions. Some departments invest in shredding technology solely to reduce the size of cumbersome, unwanted materials, while others prioritize compliance with stringent specifications, where output precision is crucial.

If you're creating energy fuels from waste, for instance, targeting specific calorific values and homogeneous particle sizes may be necessary. Look for a shredder that can deliver your desired output or allow adjustments to accommodate future changes.

7. Specific Application Questions to Ask

Operators should pose detailed, application-oriented questions to the manufacturers of plastic shredders to grasp the machine's performance capabilities in various scenarios. Considerations might include:

• For shredding confidential documents, machines with low-speed, high-torque designs can shred sensitive material while preserving fiber integrity for downstream recycling.
• For organic waste, dedicated sealing systems should be sought to protect the shredder's gearbox from aggressive materials.
• E-scrap shredders must effectively separate valuable composite materials locked within electronic devices while minimizing risks from foreign objects that could lead to costly downtimes.

8. Environmental Impact Assessment

Perceptions towards recycling and waste management vary across the U.S., necessitating that managers focus on applicable performance standards when acquiring shredders. Many modern machines are powered by energy-efficient electric motors instead of hydraulic diesel drives, which significantly reduce fire risks and lower energy consumption.

Choosing greener technologies helps ensure the cost of recycling doesn't outweigh the environmental benefits. Machines that operate efficiently save costs related to fuel consumption, enhancing ROI.

9. Establish Safety Standards for Plastic Shredder Machines

Recognizing that industrial shredding can pose risks, manufacturers have focused on engineering machinery with greater safety measures. Features include access barriers that limit operator exposure, diagnostics control panels to minimize the need for direct access, and mechanisms to halt operations when unshreddable items are detected.

Additionally, advancements in noise control minimize operator exposure, while integration of sensors helps in fire prevention. Ergonomically designed machines facilitate safer maintenance practices, reducing the risk of workplace injuries.

10. Recycle Whenever Possible

Companies often procure industrial plastic shredders to dispose of non-hazardous waste. However, choosing the wrong shredder can disrupt recycling plans. Determine the specifications needed for your output to hold value in the recycling chain.

If you plan to shred multiple materials in one machine, ensure the equipment can do so without cross-contaminating the output.
