The slow-speed, high-torque mechanism efficiently handles the tough rubber compound and embedded steel cords, gradually reducing material size through shearing and tearing actions. Hydraulic systems maintain consistent pressure for optimal shredding performance.
Primary shredding produces coarse rubber chunks measuring 50-150mm, with liberated steel wires already partially separated. Industry standards define these output specifications to ensure proper feeding of downstream equipment. The primary shred's rugged construction withstands constant abrasion from steel cords while maintaining precise blade alignment for consistent particle size distribution.
Precise Grading and Secondary Processing
Powerful magnetic separators extract remaining steel fragments after primary shredding, using high-intensity magnets to pull ferrous material from rubber streams. This process achieves over 99% metal recovery, yielding clean steel scrap for smelting operations while protecting downstream equipment from metal damage.
Advanced fiber removal systems employ a combination of air classification and vibrating screens to separate textile reinforcements. Multi-deck screening units with precisely sized mesh openings sort rubber particles into uniform fractions. Final granulation occurs in specialized mills that reduce material to 1-10mm granules through controlled impact and shear forces, producing premium rubber powder for diverse industrial applications.
