Are you searching for “tire rubber powder production details” or “how to achieve 99.7% pure rubber powder”? Tire rubber powder recycling equipment turns waste tires into 20-120mesh high-purity rubber powder—using 11 physical processing steps at room temperature to remove 99.7% of steel and fiber, with zero secondary pollution. Today, we break down its full workflow, equipment specs, and real-world applications.

Ⅰ. What is Tire Rubber Powder Recycling Equipment? Core Function

Tire rubber powder recycling equipment is an integrated “crumb-to-powder” system that combines coarse crushing and fine grinding in one plant. It takes rubber granules from upstream processing and refines them into 20-120mesh fine powder, with 99.7% purity and consistent particle size. The system also recycles steel wire (97-98% pure) and textile fiber (99.9% separated), creating 3 usable products from a single waste stream.

Its key value includes:

  • Producing 20-120mesh rubber powder that meets industrial standards for construction, sports surfaces, and energy applications.
  • Full resource utilization: steel wire is sold for melting, fiber is used as high-calorific fuel, and rubber powder replaces virgin rubber in manufacturing.
  • Room-temperature operation with wind-water cooling, which preserves rubber’s physical properties and avoids thermal degradation.

Ⅱ. 11-Step Processing Flow of Tire Rubber Powder Recycling Equipment

The system’s complete workflow covers every stage from whole tire to fine powder:

  • Debeader Machine: Removes the steel bead from the edge of whole tires, ensuring the tire can be cut and shredded without damage to downstream equipment.
  • Tyre Cutter Machine: Cuts whole tires into 4-5 large pieces, reducing their size to fit into the shredder and improving processing efficiency.
  • Tire Shredder: Shreds cut tire pieces into 50mm rubber blocks, reducing the tire’s volume by 70% and preparing it for finer processing.
  • Tire Rasper Machine: Uses rotating rasping rollers to turn 50mm blocks into 10-20mm wire-free rubber chips, loosening and separating 99% of the steel wire from the rubber.
  • No.1 Magnetic Separator: Uses a high-strength magnetic drum to separate 97% of the steel wire from 10-20mm rubber chips, collecting the wire for baling and sale.
  • Granulator Machine: Processes 10-20mm wire-free chips into 1-8mm rubber granules, with initial fiber separation to remove loose textile material.
  • No.2 Magnetic Separator: Removes residual steel wire from 1-8mm granules, increasing the steel sorting rate to 99% and ensuring the rubber is free of metal contaminants.
  • Vibrating Grading Screen: Screens 1-8mm granules to select the optimal size (1-4mm) for the grinding mill, returning oversize material for re-crushing.
  • Collector: Gathers unqualified or oversized material from the grading screen and sends it back to the granulator for reprocessing, ensuring uniform particle size.
  • Fiber Separator: Uses air separation and screening to remove 99.9% of textile fibers (nylon, polyester, rayon, aramid) from the granules, producing clean rubber for grinding.
  • Rubber Grinding Mill: Uses rotating grinding rollers to turn 1-4mm granules into 20-120mesh fine powder, with wind-water cooling to maintain powder quality and prevent overheating.
