CryoRoll is a cryogenic freezer designed for high-performance freezing of industrial materials such as rubber and plastic, typically prior to grinding or milling. It features a rotating drum where the product is exposed to liquid nitrogen. Materials such as exposed or injected with extremely low temperatures down to -196°C ensuring a high temperature gradient for rapid thermal exchange. The embrittlement and significantly improves the efficiency of grinding and milling process.
Wide range of sizes available
In the demanding recycling sector, effectively separating complex, tightly bonded materials like rubber from steel wire presents a significant operational challenge. The Dohmeyer CryoRoll for Recycling resolves this by delivering high-performance cryogenic freezing directly to your processing line. Utilizing a continuous rotating drum architecture, the system injects pure liquid nitrogen to expose industrial materials to ultra-low temperatures down to -196°C.
This rapid thermal exchange induces severe embrittlement in targeted materials, such as plastics and rubber. For instance, when processing shredded tires, the rubber becomes glass-hard while the embedded steel remains perfectly flexible. This dramatic alteration in physical properties drastically improves the efficiency of downstream hammer mills and grinders, ensuring a clean, chemical-free separation.
By integrating this advanced Dohmeyer cryogenic freezer prior to milling, recycling facilities maximize their material recovery rates, boost continuous throughput, and drastically reduce the mechanical energy traditionally wasted on warm shredding.
Processing volatile industrial materials and utilizing ultra-low temperature liquid nitrogen requires stringent hazard control on the factory floor. The Dohmeyer CryoRoll is rigorously engineered to provide a fully enclosed, heavily insulated thermal environment that actively shields your workforce from extreme cold exposure. Beyond operator protection, cryogenic technology fundamentally increases process safety during the milling of reactive substances.
Shredding specific plastics or rubber at ambient temperatures can generate dangerous frictional heat, which risks melting the materials or, worse, igniting combustible powders. The CryoRoll completely neutralizes this threat. By thoroughly pre-chilling the feed material and utilizing the vaporized nitrogen to create an inert, oxygen-displaced atmosphere within the system, it actively suppresses the risk of combustion and dust explosions.
Facility managers can confidently process challenging recycling streams knowing their operations are safeguarded by Dohmeyer's robust engineering and sophisticated thermal management protocols.
While the recycling industry does not face the exact bacteriological threats of food processing, maintaining a clean, uncontaminated processing line is crucial for high-value material recovery. Traditional mechanical shredding of rubber, polymers, or residual paint often results in the materials softening and smearing across internal machinery under high shear and impact. This causes severe build-up, clogs equipment, and contaminates subsequent recycling batches.
The Dohmeyer CryoRoll eliminates this issue through its deep cryogenic treatment. By freezing the materials well below their glass transition temperature, substances fracture cleanly and uniformly without any sticky residue left behind. Furthermore, the rotating drum's smooth internal geometry is purposefully designed to avoid dead corners where industrial fines might accumulate.
This intelligent, accessible architecture makes the equipment remarkably easy to clean and inspect between different material runs. By preventing equipment clogging, Dohmeyer ensures your facility produces consistently high-purity flakes and powders with minimal downtime.
The modern recycling landscape is constantly evolving, requiring industrial facilities to process a highly diverse array of waste streams. The Dohmeyer CryoRoll delivers unparalleled operational adaptability, seamlessly shifting from processing used automotive tires to complex electronic waste and tough polymers. Whether your facility needs to cleanly separate PVC insulation from copper wiring, recover intact metals from discarded paint cans, or safely process battery components, this cryogenic system handles the challenge with absolute precision.
Designed to accommodate various input formats, the equipment offers finely tuned cryogen dosing to match the exact embrittlement requirements of each specific material. Available in a wide range of sizes, the CryoRoll can easily scale alongside your business growth, from specialized batch recovery to massive, continuous industrial lines. Partnering with Dohmeyer guarantees your recycling plant remains future-proof, versatile, and highly competitive.
