Waste Tire Rubber Crumb Machine
The core function of a waste tyre rubber granule production line is to rapidly process whole waste tyres into reusable rubber granules, whilst simultaneously separating the steel cord to reduce subsequent processing costs.
1. Twin-shaft tyre shredder: Controls output particle size and improves subsequent separation efficiency
As waste tyres contain a large amount of high-tensile steel cord, standard shredding equipment struggles to operate stably over the long term; therefore, a twin-shaft tyre shredder is typically used for tyre pre-treatment. Through a low-speed, high-torque design, the equipment gradually shreds whole tyres into rubber chunks, effectively reducing blade wear.

In actual production, tyre sizes vary considerably—for example, between passenger car tyres, lorry tyres, and construction tyres. The advantage of the twin-shaft design lies in its high adaptability, as it can automatically adjust the shredding force according to tyre thickness. The inclusion of a rotating screen within the equipment allows for control over the size of the rubber chunks, preventing oversized material from entering the next stage of the process and improving the stability of subsequent steel cord separation.
Compared to direct fine-shredding processes, preliminary coarse shredding not only reduces energy consumption but also minimises equipment vibration and bearing loads, making it suitable for continuous, high-volume operation.
2. Steel Cord Separator: A Critical Stage Determining Rubber Granule Purity
Pure Rubber Granules
After the tyres have been shredded, the rubber chunks enter the steel cord separator, also known as heavy-duty crushing and separation equipment. The core function of this equipment is to thoroughly separate the rubber from the internal steel cords.
Steel cord separators typically employ a high-strength knife roller structure, using compression, shearing, and tearing to gradually separate the rubber from the steel cords.
In practical applications, the steel cord separation rate is often one of the key indicators used to measure equipment performance. A stable separation system not only enhances the purity of the rubber granules but also increases the value of the recovered steel. For tyre recycling plants operating on a long-term basis, the volume of steel cord recovered is itself a significant source of revenue.
Furthermore, the current waste tyre recycling industry has moved beyond simple shredding to focus more on the equipment’s continuous operation capability, maintenance costs, and product consistency. Particularly when processing medium to large truck tyres, the strength of the cutting tools, bearing stability, and the coordination of the entire conveyor line all directly impact output.
