Detailed Manufacturing Process of Rubber Powder

The transformation of waste rubber into valuable rubber powder involves a sophisticated multi-stage process, forming a complete rubber powder production line. This intricate system is designed to remove contaminants, achieve precise particle sizes, and ensure the purity required for advanced rubber powder uses.

1. Raw Material Collection & Inspection: The process begins with collecting discarded rubber products, primarily waste tires. Each batch undergoes rigorous initial inspection to identify and reject contaminated or unsuitable materials, ensuring only high-quality feedstock enters the system.
2. Pre-treatment & Shredding: Large rubber items are first pre-treated to remove large metallic components (like tire beads) and then fed into powerful shredders. These machines break down the rubber into smaller, manageable chunks (typically 50-100 mm). This stage is crucial for efficient subsequent grinding.
3. Granulation & Magnetic Separation: The shredded rubber chunks are then processed through granulators, which further reduce the size to finer granules (e.g., 10-30 mesh). During this stage, multiple stages of powerful magnetic separators are employed to extract any remaining ferrous metals. This is a critical step to prevent damage to downstream equipment and ensure product purity.
4. Fiber Separation: Textile fibers (nylon, polyester) present in tires are lighter than rubber. Air separators, often using zig-zag patterns, are utilized to effectively separate these fibers from the rubber granules, further purifying the material.
5. Grinding (Ambient or Cryogenic): This is the core of rubber powder production, determining the final particle size and quality.
   • Ambient Grinding: Rubber granules are fed into high-speed mechanical grinders (e.g., cracker mills, turbo mills). The friction generated during this process breaks the rubber into finer particles. This method is energy-efficient for coarser powders.
   • Cryogenic Grinding: For producing fine rubber powder (e.g., 40 mesh and finer), the rubber is first embrittled by cooling it to extremely low temperatures (below its glass transition temperature) using liquid nitrogen. The embrittled rubber then shatters easily into powder when fed into a mill. This method yields very fine, uniform, and clean powder, ideal for demanding rubber powder uses like coatings and high-performance compounds.
6. Screening & Classification: The ground rubber powder is then passed through a series of vibrating screens or air classifiers. These systems precisely separate the powder into different mesh sizes (e.g., 30 mesh, 40 mesh, 60 mesh, 80 mesh, 120 mesh), ensuring consistent particle size distribution for specific applications. Oversized particles are typically recirculated for further grinding.
7. Quality Control & Packaging: Throughout the entire process, stringent quality control checks are performed at each key node. This includes monitoring particle size distribution, moisture content, ash content, and purity. Once certified, the rubber powder is carefully packaged in moisture-resistant bags (e.g., jumbo bags or 25kg bags) to maintain its quality during storage and transport.

The emphasis on robust manufacturing processes, including thorough metal and fiber separation, ensures that Rubber Powder-821 is of the highest purity, minimizing impurities that could compromise the final product's performance in its intended rubber powder uses. Our dedication to precision in particle sizing allows for optimal dispersion and integration into various polymer matrices.
