Successful Exhibition for R4
R4 recently exhibited at RoadExpo, Scotland's annual exhibition and conference for highway maintenance and traffic management professionals & were inundated with enquiries about suitable applications for tyre bales.
Michael Kerr, R4's Business Development Manager, was very pleased with the quantity and calibre of the visitors at the show. All the visitors he spoke to were very excited about the prospect of using tyre bales as a recycled alternative to virgin material in road construction applications, and he even had some new potential uses suggested by the visitors. "Thanks to all the people who took time out to call at our stand and to all the customers who have contacted us since as a result of our exhibition," said Michael.
R4 extremely good radio presentation - R4 Limited are proud to sponsor local community radio station xtreme FM. The radio station is part of the Brownlow Area Youth Project, a programme that supports young people from a variety of cultural backgrounds.

Wood Replacement Products
Dena is a Nanometric Process Intensification Technology Company in the UK, who offer a number of reactor based processes to produce a high value product and to give zero waste, emission free tyre recycling.
A variety of durable products can be produced from 100% recycled tyre rubber and thermal material.
The recycled material is tough and durable and easy to clean, which makes it perfect for floors, trailer boards, wall liners, wood replacement, seawalls, ports, marina's and extreme conditions. This material is stronger than others, is impervious to water, UV resistant and repels fuels, making it the perfect choice for decking, foot paths, tiles etc.
The products made from it will not crack, rot or split, so will last longer. The material is an environmentally friendly, economically viable, easy to maintain and a superior choice for a number of products. The material can also be recycled several times given good control of the original and the recycling process.
This technology is very flexible and can do all types products such as irrigation hoses and accessories including dripping pipes and leaky pipes. Home & building construction, replacement of plywood casing boards for wall, ceiling and pillar construction, outdoor wood replacement and other general products.
One key issue with tyre recycling is disposal of both the steel and the fabric recovered from the tyres. The clean steel can be sold to be recycled, for the fabric recovered Dena has developed a number of processes to use the waste fabric and produce a number of insulation and sound proofing products.

Pure Rubber and Clean Steel
Tyre recycling plants from Eldan Recycling A/S are all of modular design. Using the modular approach a large number of combinations can be supplied both with regard to the plant capacity as well as the output sizes of the various products.
The modular approach covers all customer requirements for 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 Eldan Plants are "Multi-Size" Plants giving the customer total control over the production of a various range of output sizes. This is achieved by the simple and quick changing of the screen combination in the machines when you wish to produce a different range of output sizes.
Eldan Recycling delivered and installed its first complete tyre recycling plant back in 1991 and has since then developed and optimised the process to obtain the best possible purity of the rubber granulate. This purity is very high - up to 99,9% free of liberated steel and textile in the standard plant. This purity is obtained through special build equipment such as classifiers and aspirators that operate by means of the "air flow" principle.
Over the years more and more applications for rubber have been developed and concurrently with this the request for a higher purity. For this purpose Eldan Recycling has developed the quality upgrading modules enabling an improved purity of both the main fraction and the undersize fraction.
After separation/cleaning in the plant the main fraction is passed through an additional separation process, where pure "black rubber" is separated and the "light fraction" passes over yet another classifier giving the entire fraction a purity of up to 99,99%.
It is also possible to refine the undersize for possible impurities. In the Eldan quality upgrading module for the undersize, the granulate is passed through an air cleaner, before it proceeds through two further steps of classifiers and aspirators as final treatment giving a purity of up to 99,99%.
There is also a demand by tyre processors to improve the purity of the steel fraction generated in the recycling of tyres. This involves the reduction of the rubber and textile contamination in the steel fraction which would improve the sales possibilities and at the same time increase the value of the steel fraction.
For this purpose Eldan Recycling has developed 3 different systems enabling purities of respectively 95-97%, 97-98% and 98-99% pure steel. These systems are also of modular design which means that the equipment can be either installed in-line with an existing plant or as a stand-alone system.
The first solution is a very "low-energy" solution, where the steel fraction is passed through a screening system. The oscillating screening system produces a cleaner steel fraction, which is passed over a magnet system increasing the purity of the steel.
The second solution has the advantage that it can be installed as a stand-alone unit enabling cleaning of the contaminated steel from a stockpile. The first stage is a Multi-Purpose-Rasper which size reduces the steel further at the same time liberating more of the rubber content. The Multi-Purpose-Rasper is fed by a Tumble Back Feeder that ensures optimum feeding of the Rasper. After this initial process the steel is transported to a specially designed magnet system, which "flings" the steel and liberates the impurities during the process. In the final step the steel is passed over a zig-zag separator where the air flow removes the light textile impurities.
The third solution is the "Delux" version that offers optimum cleaning of the steel fraction. This system also includes the Multi-Purpose-Rasper for size reduction of the steel as the first stage. After this the steel is passed over the screening system which was mentioned under the first solution. By combining elements from the two first solutions it is possible to obtain the excellent purity of 98-99% pure steel again providing the customers and users with improved and numerous possibilities.
All the above-mentioned solutions are "proven technology" as they have all been installed with existing Eldan customers and the results and processes have been tested and developed in co-operation between Eldan Recycling and the customers.
Eldan Recycling is one of the few companies, delivering equipment to the recycling industry, which has its own production facilities ensuring the quality of the product and the flexibility of the production program.
Eldan Recycling is the Turnkey Supplier of complete plants, i.e. the customer only deals with one partner from the first approach over the projecting stage to the customized solution. Eldan's technical staff is responsible for design and development just as Eldan's project managers and supervisors are in charge of the project work, installation, erection, training and commissioning of the plant.
Despite the excellent product quality Eldan Recycling has very competitive prices. In addition to its range of standard plants and machines, the company tailors solutions to specific customer requirements.
