“The project involved handling 14 000 tonnes of old tyres located near the city of Tartu which were dumped there over the years. They remained in the environment after tyre manufacturer ceased operations,” Rainer Pesti, Marketing and Communications Manager of Ragn-Sells, notes.
Project conditions were quite extreme: the area was covered with tyres and they were mixed with construction waste. Normally, tyres are very complex in terms of material recycling and processing them for reuse is a difficult task since they are made up of many different materials. Tyres contain rubber but inside there’s also textile and metal. Shredded tyres from this project will be sent for further processing.
Strong technical support
“I would like to highlight Tana’s strength in providing support quickly in all situations. Both the support of the factory and the aid provided by the Estonian representative,” Pesti says.
In addition to robust TANA machines, Tana’s strong technical support played a big role in the intense project. It is vital that the machines are not standing inactive and needed parts can be quickly replaced.
“This type of crusher machine technology is very durable but because the machine has to withstand heavy loads there is always a possibility that, for example, the blades wear out or a shaft breaks”, Pesti continues.
The most versatile shredder
TANA high-torque shredders make it possible to shred tyres to a very homogeneous 80 mm (3″) particle size in just one pass and separate most of the metals during the shredding process. An overband magnet separates most of the metal wires directly from the shredded material flow on the conveyor. Once separated, shredded tyres and metals can be sold and reused in many ways.
Instead of tearing the tyres, the TANA Shark cuts them almost like very efficient scissors. The particle size can be adjusted by changing the counter-knife setting on the side door and choosing a suitable rotor screen. The bigger the particle size, the higher the capacity. By using the operating program for tyres, the machine automatically adjusts itself to the optimal level, thereby protecting the machine and optimizing operating costs.
