Semi-Automatic Tire Recycling Production Line

Semi-automatic tire processing production line is based on the core structure of “front-end cutting and pre-processing + back-end crushing and sorting”, which is suitable for small and medium-sized recycling scenarios, with the following equipment configurations and processes:

I. Composition and function of core equipment

Front-end pretreatment equipment

Tire bead cutter: Used to cut out the tire sidewall steel wire bead, separate the tire crown and sidewall, and facilitate subsequent cutting and processing.

Tire cutting machine: cut the tire into strips of rubber with a width of 30-40 mm after cutting the bead, with adjustable spacing between the knives to adapt to different specifications of tires.

Tire chunking machine: further cut the rubber strip into 3-5 cm chunks to improve the subsequent crushing efficiency.

Steel wire separator: complete separation of bead steel wire bundles from rubber blocks, ensuring steel wire recovery rate ≥95%.

Back-end crushing and sorting equipment

Double-roller mill: Through the relative extrusion and shearing of two rollers, the rubber block is crushed to 5-10 mm particles, and the residual steel wire is separated simultaneously.

Magnetic separator: utilizing strong magnetic field to adsorb the residual steel wire (≤2 mm) in the rubber particles, metal recovery rate ≥99%.

Air separator: Based on the density difference, separate nylon fiber and rubber particles through airflow, fiber purity ≥ 90%.

II. Process Flow and Parameters

Pre-treatment stage

Human-assisted operation: the operator places the tires in the bead cutter station, cuts the sidewalls and then cuts the strips and blocks in turn, and the stability of the equipment needs to be monitored throughout the process.

Steel wire separation: the rubber material after cutting blocks is extracted from the whole bunch of steel wires by the steel wire separator, and the residual steel wire content is ≤2%.

Crushing and sorting stage

Rough crushing: the rubber block is initially crushed by double-roller mill, with adjustable roller spacing (5-15 mm) to control the particle size of the discharged material.

Magnetic separation and fiber sorting: the crushed mixture passes through the magnetic separator (magnetic field strength ≥3000 gauss) and air separator (wind speed 5-8 m/s) in order to realize the efficient separation of steel wire, fiber and rubber.

Finished product specification:

Rubber particles: particle size 5-10 mm, can be directly used for plastic runway or recycled rubber production.

Steel wire: length 50-200 mm, purity ≥98%, suitable for metallurgical furnace.

Nylon fiber: length 1-5 cm, purity ≥90%, used in composite materials or heat insulation layer.

III. Technical advantages and applicable scenarios

Modular design: support flexible increase or decrease of equipment (e.g. increase the number of magnetic separation stages or sorting precision), adaptable to the demand of low and medium capacity of 3-5 tons/hour.

Cost-effectiveness: the investment of the whole line is 40-60% of the fully automated equipment, manual intervention reduces the complexity of the automated system, and the maintenance cost is reduced by 30%.

Environmental compliance: the use of pulse dust collector (dust concentration ≤ 10 mg/m³) and closed sorting system, no waste water, exhaust emissions.

Air separator Sorting fibers and rubber particles Wind speed adjustment range: 5-12 m/s4

The production line balances efficiency and cost through human-machine interaction, providing a cost-effective recycling solution for regionalized tire recyclers.
