Faaborg, Denmark -- A new Eldan Recycling mining tyre recycling system can turn huge waste mining tyres into reusable rubber granulate, powder and clean steel wire. This tyre recycling equipment enables processing whole car and truck tyres including super singles, earth mover tyres, OTR etc. De-beading of the tyres will not be required prior to processing in the Eldan recycling systems. The company uses a modular approach, which cover all customer requirements on equipment to process at different levels down the "recycling road", i.e. production of shreds, chips, granulate and powder - all having their own platform within recycling.

The various standard plants are "multi-size", which give the customer total control over the production of a various range of output sizes. By a simple and quick change of the screen combinations in the machines a different range of output sizes is produced.

Rubber granulate purity up to 99,9 percent

The output rubber purity is today very high. The typical rubber granulate purity in the standard systems is up to 99,9 percent free of liberated steel and textile. By adding a quality upgrading system it is possible to produce "black gold" - which is rubber powder up to 99,99 percent free of liberated steel and textile, and 100 percent free of metals, glass and stones. If desired the liberated steel wire can be further cleaned into a steel fraction which is 99 percent free from foreign material, as textile and rubber, and has a heavy weight density of +700 kg/m3.

In 2011 Eldan was faced with a huge problem to find a solution for recycling of mining tyres. "We where contacted by a new customer, who had been searching for a solution to process mining tyres for a long time. By combining our tough equipment and our long proven technology, we presented a solution to the customer on which we did a very successful test run in the autumn of 2011" says Bjørn Laursen, product manager for tyre recycling at Eldan Recycling. "Since this first test run, we have received many quote requests from interested customers. We have once again managed to turn a huge waste problem into a cost beneficial business."

According to the customer’s specific needs

The mining tyre recycling system can process mining tyres of typically 3 to 4 meter diameter and weight 4 to 6 tons per tyre, at a capacity of approximately 4 to 6 ton per production hour. Since the mining tyre recycling system is combined with the standard Eldan tyre recycling systems, the output can be decided according to the customer’s specific needs of output granulate size and quality.

The mining tyres are first handled and pre-cut by a heavy duty demolition shear into pieces which fit the in-feed of the Eldan Heavy Duty Super Chopper (SC-HD). This machine is especially designed to process voluminous and tough waste. In the Heavy Duty Super Chopper, the big pieces of mining tyre are processed into tyre shreds, and free steel wire is liberated and removed from the shreds by a powerful Overband Magnet. The tyre shreds are further processed in the Eldan granulation and separation plant. Depending on your specific requirements a high quality rubber granulate and clean steel wire can be produced.
