Cryogenic Mill Applications in Recycling: Rubber, Plastics, and Composite Materials

Cryogenic mills are stand-alone devices that work like high-convenience blenders but are suitable only at very low temperatures; they typically use liquid nitrogen to chill materials and render them so brittle you can smash a spoon against them. These materials can break into little chunks of rubber, plastic or composite without melting or getting sticky. Cryogenic milling offers an excellent way to break up hard or mixed materials. Cryogenic Technology to Enable mechanical recycling Nanjing Chishun has developed a series of cryogenic grinding machines for Specific waste areas such as tyres and resources waste can be recovered at the end of its life, reducing the environmental waste. It sounds challenging to process various materials with a single machine, and yet it’s doable — when the machine is cryogenic milling

Obtaining High Performance Particle Size Reduction in Composite Recycling by Using Cryogenic Mills

Certain composite materials are a real bear to break down, given they are often composed of multiple substances that have been glued or bonded together. Most composites crumble at typical temperatures, melting or sticking to create irregular particles that are difficult to recycle effectively. Cryogenic mills from Nanjing Chishun cool the composites to very low temperatures that make them brittle and easy to shatter into small, consistent particles. The cool temperature also prevents heat accumulation; the material does not change its chemical or physical properties in any way due to milling. For instance, carbon fiber reinforced plastics can be mill into synergetic powders without interrupting the fibers, here by preserving its value further in a loop or as filler. Recyclers can reach particle sizes below 100 microns using our cryogenic grinding process — something that would not be possible with other processing methods. The process also reduces the need for sifting because disparate parts break up better once crushed into finer pieces. While few recycling plants have actually witnessed the capabilities of this technology in raising their yield and reducing waste being sent to landfills. Additionally, the cryogenic method prevents the generation of dust and odour experienced in conventional hot grinding making the workplace more healthy and clean. AFM’s machine designs enable operators to change milling speeds, cooling rates and grinding pressure, ensuring a variety of composites can easily be machined by clients. This adaptable control allows recyclers to manage batches of mixed materials without switching machines or setups. It is also one thing to break materials down; it’s another to do so in a way that allows them be used for other products

Cryogenic Milling Solutions for Rubber & Plastics

Reprocessing rubber and plastic frequently involves high-throughput creation of raw material. Because rubber is elastic and plastics can be soft or sticky, it’s difficult to break them into small pieces without heating them up or otherwise destroying them. Nanjing Chishun’s machines for bulk cryogenic milling are built to chill huge quantities of rubber or plastic waste until they become brittle and can be shattered into small particles. This process bypasses issues like melting or clumping, which occur during traditional milling. Old tires, for example, are difficult to recycle because of embedded metal parts and rubber hardness that defies shredders, but when they become cold and brittle in cryogenic mills, the rubber shatters and cleanly separates from steel belts. Our big ones, with machines that feed and cool themselves, minimize downtime and ramp you up to desired productivity. The cold grind also limits the wear on machine parts, which saves money in repairs and maintenance. Nanjing Chishun users say they have more uniform sizes and purer (rubber or plastics) powder compared to other methods. There are times you have to grind rubber and plastic waste together – our cryogenic mills do that as well, generating a homogeneous product ready for reuse. Large mass production milling machines have safety features to handle nitrogen safely and minimize risk during operation. From little recycling plants to immense factories, these machines are going to do the job for you and will continue on doing the things that they are meant to do. The cooling and grinding in one go saves energy — which also brings down the recycling cost across-the-board. Picking the right cryogenic milling system from Nanjing Chishun means recyclers receive machines better suited for challenging material, high-volume output and cleaner end-product result helping recycling become a more efficient undertaking

Here's Why Cryogenic Milling is Essential for Rubber and Plastic Recycling Sustainability

We need to recycle rubber and plastic, if we want saving our environment. These materials are found in lots of stuff — tires, bottles, packaging. When they are old or thrown away, we need smarter ways to recycle them so that they don’t end up as trash that is bad for the rest of nature. This is where cryogenic milling comes into the picture Cryogenic milling involves very cold temperatures, often with liquid nitrogen while rubber, plastics or other composite materials are frozen prior to grinding. If this material is cooled to liquid nitrogen temperatures it will freeze to be very hard and brittle. Which is easy to crush and grind them into smaller pieces or powder. Then, those small pieces can be reused in new products

Another reason cryogenic milling is important for recycling is that it keeps material clean and pure. Rubber and plastic can become stuck or soft when ground at normal temperatures. This can make it difficult to mill into a fine powder and can cause the material to stick to the equipment or mix with soil and other debris. But the material remains dry and hard in cold temperatures, making the milling process far smoother and less messy. This has the effect of making recycled material higher in quality and more valuable

Another thing to note is cryogenic milling it saves you power. And because the materials are brittle, machines do not have to work as hard to break them down. This requires less electricity, which is better for the environment and allows companies to save money. And last but not least, it has lower dust production and noise compared to other solutions making it safer and more comfortable for you to work with

Nanjing Chishun specialized in manufacturing rubber/recycle machines and now Chishung Recycling Technology has applied its R&D strengths to grinding (milling) machines, especially for recycling rubber and plastics. Their machines assist recycling companies in turning waste into valuable raw materials that can be put to use over and over. Through cryogenic grinding we also provide power and resource-saving measures while guaranteeing a clean and natural environment for future generations

How Cryogenic Grinding Aids the Recyclability of Rubber and Plastic Waste

Recycled rubber and plastic are so useful, but the value of them depends on how good the recycled material is. If the recycled materials are large, dirty or sticky, they can be difficult to use in new products and have a lower value. The quality of the recycled materials is enhanced by cryogenic milling, which increases their market value. Low-temperature mill machines from Nanjing Chishun are one step in making that possible

Cryomilled rubber, plastic and composite powders transfer to very even fine pow- der of various scattering upon cryogenic milling. This fine powder is cleaner and can more readily be mixed with new raw materials for products such as tires, shoe soles or plastic parts. Manufacturers are willing to pay more for recycled powder because it’s steady and it stands up. That means recycling companies can sell their materials for more money

Finally, cryogenic milling helps the recycled materials to retain their properties. For example, the rubber, if ground at a hot temperature, can become soft, and slippery, therefore, it becomes of less useful; frozen the material hardens and becomes brittle. Freezing enhances the structural integrity of recycled rubber, which allows it to be used in more products and to serve more. Cryogenic milling also makes it easier to separate the composite waste materials. Some waste is made of two or more materials, mixed, specifically, plastic and rubber. The cryogenic milling makes it easier to break the composite, allowing the recycling company to further recycled the part more efficiently. This bone improves the value of products and market prices. Nanjing Chishun’s new technology of cryogenic milling helps recycling business to produce products with good quality that can withstand the markets price and cut themselves a market share. This promotes a circular economy of resource reuse. Therefore, the cryogenic milling is a powerful step towards making recycled rubber and plastics useful and more valuable than the waste. Nanjing Chishun technology is a green mine that business can use to grow their market and serve their purpose
