A fully automatic tire shredder is an industrial device specifically designed to break down whole waste tires into rubber particles or blocks of a specific size. Its core design goal is to achieve continuous, efficient, and safe automated processing, minimizing human intervention and improving processing efficiency and material purity.
The machine operates based on physical mechanical force. After startup, the tire to be processed is fed into the crushing chamber at a uniform speed via a feeding system (such as a conveyor belt). The core component inside the chamber is one or more sets of rotating cutter shafts made of high-strength alloy steel, with specially heat-treated moving blades mounted on them. When the tire enters the working area of the cutters, these high-speed rotating blades work in conjunction with fixed blades (or counter-rotating blades) to generate powerful shearing, tearing, and compressing forces, forcibly breaking down the tough tire rubber, the internal steel cord, and the fibrous skeleton material.
The entire process is typically divided into two stages: coarse crushing and fine crushing. The coarse crushing stage first breaks the entire tire into larger rubber blocks and initially separates some of the steel wires; the fine crushing stage further grinds these rubber blocks into smaller, more uniform particles, while the subsequent sorting system completely separates the rubber, steel wires, and fibers.
