The Ultimate Guide to Plastic Shredders in the Recycling Industry

Plastic shredders are specialised machines that are essential to the recycling industry. These industrial shredders — also known as plastic shredding machines, or plastic recycling machines — are specially designed to break down plastic materials into smaller, more manageable pieces for recycling, effectively reducing waste and minimising environmental pollution. 

By breaking down large plastic items into manageable pieces, shredder machines for plastic help facilitate efficient recycling, help conserve resources, and significantly reduce the environmental impact of plastic waste. Their importance lies in their role in promoting sustainable waste management practices and supporting the circular economy.

How Do Plastic Shredding Machines Work?

The design of a plastic shredder is elegant in its straightforwardness; it uses sharp blades or rotating drums to slice or shred plastic materials into smaller pieces. Available in a range of sizes and configurations, these machines cater to various needs, from compact units for household use to heavy-duty systems designed for large-scale industrial operations. The shredding process starts when plastic waste is fed into the machine, where it encounters the cutting mechanism. Depending on the shredder type, this mechanism may feature rotating blades, counter-rotating shafts with interlocking teeth, or high-speed drums with sharp edges. As the plastic moves through the shredder, these components apply mechanical force to cut, tear, and crush the material into smaller fragments.

Why Do We Need Plastic Shredding Machines?

Plastic shredders have become indispensable machines within the recycling industry. These machines are essential tools when it comes to managing and processing plastic waste effectively, and significantly reduce the volume of plastic waste and prepare it for further recycling and reuse.

Plastic shredding machines are build to help us achieve the following: 

They Optimise Recycling

Plastic shredding machines are integral to the recycling process as they break down large volumes of plastic waste into smaller, manageable pieces. This step is essential for transforming discarded plastic into materials that can be easily processed and repurposed into new products. By shredding plastic waste, these machines not only make recycling more feasible but also play a vital role in diverting plastics from landfills. This reduction in landfill waste helps lower the demand for new, virgin plastic production, supporting a more sustainable approach to managing plastic resources.

They Reduce Environmental Impact

Plastic pollution is a serious environmental issue that threatens wildlife, contaminates natural habitats, and actively worsens the climate crisis. By helping us recycle plastic waste, shredding machines help us fight the plastic problem. Plastic shredders reduce the environmental footprint of plastic pollution by aiding in the conservation of natural resources and decreasing greenhouse gas emissions. Through effective shredding, plastics can be processed into reusable forms, thus minimising the harmful effects of plastic pollution on ecosystems and supporting efforts to protect the environment.

They Help Promote a Circular Economy

Plastic shredders are a critical step in advancing the circular economy, a model focused on reducing waste and optimising resource efficiency. Plastic shredders can be used in a closed-loop system, in which materials are continuously reused and recycled. By helping us recycle plastic waste, these machines contribute to a sustainable economic model, thereby reducing the need for new raw materials and minimising waste. This promotes resource conservation and aligns with the goals of a circular economy by ensuring that materials remain in use for as long as possible.

They Optimise Waste Management

Efficient waste management is a significant step in achieving clean and healthy communities. Plastic shredding machines enhance this process by decreasing the volume of plastic waste, making it easier to handle, transport, and dispose of properly. This improved efficiency helps streamline waste management operations and prevents littering and environmental contamination. By reducing the physical bulk of plastic waste, shredders support more effective waste management practices and contribute to cleaner urban and natural environments.

Types of Plastic Shredders

Single Shaft Shredders

Single shaft shredders operate with a single rotating shaft equipped with rotary blades to break down plastic waste into smaller fragments. These machines are ideal for processing softer plastics, such as films, and can produce finer output sizes. Featuring a single rotating shaft with sharp blades, single shaft shredders effectively handle a variety of plastic materials, including films, bottles, and containers. Applied Machinery provides a range of high-quality Single Shaft Genox Shredders, including the Behemoth (also known as BH Series), the King Kong series (a.k.a the K Series), and the Vision series (also known as the V Series), which is designed to take care of plastics like mouldings, purgings and lumps. 

Twin Shaft Shredders

Twin shaft shredders use two shafts with interlocking blades to break down thicker, more rigid plastics into larger pieces. These machines are ideal for processing robust plastics like pipes and car parts, resulting in larger output sizes. Dual shaft shredders, with their counter-rotating shafts and interlocking teeth, offer enhanced cutting efficiency and versatility. They are commonly used for shredding bulky or thick plastic items, such as automotive parts and electronic waste. Applied Machinery stocks a range of high-grade Genox shredders, including the Single Shaft Mino (also known as the M Series), which is suitable for shredding various plastics, plastic drums, and containers.

Components of a Plastic Shredder Machine

A high quality plastic shredder machine is typically built from a combination of core components that work in harmony to shred plastic waste. These components typically include: 

The Cutters: The blades are arguably the most critical part of a plastic shredder, responsible for the actual shredding process. In order to optimise cutting force and productivity, high-strength cutters are crafted from premium, heat-treated steel alloys. 

The Gearbox: The gearbox is designed with a shock-absorbing mechanism, enhancing the overall durability of the shredder. This feature minimises vibrations during operation, ensuring reliable performance and extending the lifespan of the machine.

The Screens: Equipped with quick-change screens, plastic shredders allow for precise control over particle size. These screens regulate the output, enabling operators to achieve the desired dimensions of shredded material efficiently.

The Shaft Couplings: These shredders are built with shock-absorbing shaft couplings that connect the gearboxes to the blade shafts. This design reduces stress on the components, improving the machine’s resilience and contributing to a smoother operational process.

The Motor: These shredders are built with shock-absorbing shaft couplings that connect the gearboxes to the blade shafts. This design reduces stress on the components, improving the machine’s resilience and contributing to a smoother operational process.

Maintenance And Troubleshooting Of Plastic Shredders

Different waste shredders are designed with various shredding systems, such as single and twin shaft configurations. Choosing the right shredder for your business and maintaining it regularly is essential for optimal performance. Routine maintenance, including lubricating moving parts, cleaning the shredding chamber, and inspecting and replacing components, helps prolong the shredder’s lifespan and minimise repair costs. Common issues like overheating, blade damage, clogging, and motor or gearbox failure can often be resolved by adjusting the feed rate, sharpening or replacing blades, clearing blockages, or repairing or replacing faulty parts. Regular maintenance and troubleshooting are crucial to keeping plastic shredders running smoothly and reducing downtime.
