Germany-based equipment manufacturer The Pallmann Group has announced that its Tiger single-shaft shredder is a universal machine that can be used in numerous applications. Originally developed for reprocessing tires, the life of the cutting tools, as well as the output, have performed better than expected, making the shredder ideal in many applications, the company says.
The Tiger-type single-shaft shredder was originally developed to separate the rubber in tires from steel reinforcements. Rotor blades can last through more than 8,000 tons of material. The wear segments on the rotors last for more 80,000 tons of material processing. The company adds the blades can be changed quickly using clamping technology reducing downtime.
Tires can be cut into strips in a single step. There is no need for pre-cutting of the tire into the normal shreds of 100 by 100 mm or 150 by 150 mm. The standard sized Tiger, the PSRT 1000 x 1250, achieves an average throughput of 3.5 tons per hour with a final particle size of 15 mm.
The unit’s patented construction enables the direction of rotation of the rotor to be changed regularly. The particular shearing and cutting action results in a purity of the steel fraction of more than 97 percent in a single process step, doing away with the need for a separate machine for subsequent cleaning of the steel fraction. In addition, more than half of the material has a particle size of 0 to 8 mm, which means that downstream size reduction technology can be designed to be considerably more cost-effective.
The Pallmann Tiger is typically used together with other family members, Lion, Panther and Lynx, to form a complete waste tire recycling plant. It can be used as a stand-along module, or integrated into existing plants.
There are numerous other possible applications for the Tiger, according to Pallmann. For example, it can be used for cleaning wire in tire reprocessing plants, size reduction of safety flooring, carpets, turnings and millings, breaking up electric cables, electronic scrap and rubber seals with steel reinforcement, and other tasks.
