Next Generation RecyclingFrom concept to completion
New opportunities in the integral project approach for tyre recycling delivered by Van Aarsen Rubber Technology
Van Aarsen, a world-leading turnkey project supplier introduces “Next Generation” tyre recycling systems for the production of tyre derived value added rubber powders and granules.
Van Aarsen became involved in Tyre Recycling during the early eighties when a former employee took the first steps in tyre recycling. When leaving the diversification strategy in the late eighties their roads split.
Re-entering the tyre recycling market is consistent with Van Aarsen’s strategy to provide custom made solutions from concept to completion.
At the beginning of 2004, Van Aarsen acquired Konings Rubber Technology B.V.; a world-leading turnkey project supplier for the tyre recycling industry. The acquisition of Konings Rubber Technology B.V., with its impressive reference list, formed the starting point of the development of Tyre Recycling Systems of the Future.
Its Van Aarsen’s philosophy to apply exclusively designed machines and systems for the complicated process of recycling of tyres. An innovation programme called “Next Generation” recycling systems is in its round up testing and implementation phase. The progress made in quality output, efficiency, flexibility, maintenance and durability show great promise for future tyre recycling professionals.
Van Aarsen now offers turnkey systems of unparalleled performance, and individual machines that can be easily integrated into existing multi-machine processing lines.
History 
Van Aarsen International, a global leading company in feed milling technology, with nearly 60 years of experience in process technology and turnkey-solutions, acquired (Konings) Rubber Technology at the end of 2003.
Van Aarsen Rubber Technology
Due to this acquisition Van Aarsen Rubber Technology has over 20 years experience and expertise in tyre recycling solutions worldwide. Together with the knowledge, the experience and the professional approach of the parent company van Aarsen Rubber Technology offers fully integrated turnkey projects for the production of high quality tyre derived rubber-granulates and powders.
Complete Tyre recycling systems
Design and construction of turnkey tyre recycling systems but also optimisation and modernisation or extension of existing installations. Van Aarsen Rubber Technology has the engineering and project management capabilities in house to carry out feasibility studies and to design and construct tyre-recycling projects worldwide.
Advanced tyre recycling equipment
Shredding, grinding granulating and pulverizing, ambient as well as cryogenic, for truck- or car-tyres. Van Aarsen Rubber Technology equipment can be easily integrated into existing multi machine lines. Our systems are designed and constructed to give you the ability to produce at the lowest costs, environment-friendly with the highest possible quality for the end-product.

Process
1. Shredding
The first step in the VAN AARSEN RUBBER TECHNOLOGY process is the SRS 1300/1300 S shredder. Shredding is an ambient mechanical process. The whole tyres including the beads are cut into pieces with a size of approximately 100 x 150 mm. In the shredder, water is added as a lubricant as well as for cooling and dust preventive. The used water goes into a settling tank. The clarified water leaves via the overflow into the sewer. What remains is settled street-dirt (sand ,stones, glass).
After the shredder the intermediate stock could be situated. This intermediate stock enables you to keep processing when the knives of the shredder have to be replaced. The shreds are fed into the main grinder with the intake dosing hopper with rotating scraper.
2. Main Grinding
The second step in the VAN AARSEN RUBBER TECHNOLOGY process is the RTG 800 /1250 main grinder. Main Grinding is an ”ambient” mechanical process and is a grinding and not a cutting treatment. The tyre shreds are crushed between toothed rotor and stator tools. The shreds include the steel wires from the beads, which are of help during the grinding process. The toothed tools are grinding tools, hence they do not necessary need to be sharp.
In just this single step the size of the shreds is reduced from (100*150 mm) to a granulate of 0-20 mm of which already 20 % is less then 2,0 mm due to the special design of the machine which is unique in the market. Another benefit of this unique design is that over 96 % of the steel is liberated during this process.
The grinding temperature of approx. 80 degrees Celsius is maintained by adding process water in the main grinder. The water added into the man grinder evaporates during the grinding process and is cleaned in a wet-filter to remove the dust before it is released to the environment.
The ground rubber with the liberated steel wires is transported via a vibration conveyor. The steel is separated from the rubber by several magnets. The separated clean steel is led via belt conveyors to containers outside the production building. The clean steel without rubber is ready for sales.
The ground rubber and fiber mixture is pneumatically transported to the primary screening machine and separated in 3 different grades. In this example we take 0-2 mm, 2-4 mm and 4-20 mm.
The fibers in the rubber are separated in the primary sieving machine and pneumatically transported to the central dust aspiration.
3 Granulating
The third step in the VAN AARSEN RUBBER TECHNOLOGY PROCESS is the GN 800/1200 granulator.
As example we take an input of 80 % passenger car tyres and 20 % truck tyres, due the fact that we have an mixed input we have to go down in granulate size to 4 mm to release all the textile incorporated in the passenger car tyre to produce a clean and marketable granulate.
Over 60 % of the output of the main grinder has a granulate size bigger than 4 mm but 40 % is already smaller than 4,0 mm.
The rubber particles larger than 4 mm are fed into the granulator(s) where the rubber is granulated into particles smaller than 4 mm. The rubber granules return to the primary sieve. The granulating process is ambient and mechanical.
The wear on the knives and screens of the granulator is relatively low, because more than 96% of the steel is already removed in the main-grinding process.
4 Secondary cleaning section
The rubber 0-2 mm is separated into two sizes 0-1 mm and 1-2 mm together with the 2-4 mm we have 3 separate product streams.
These 3 granulate sizes are still consist fiber-dust, fiber-cord and impurities like small peddle stones, pieces of glass, brass from the tubes etc.
- The fiber dust will be taken out by sifting units located in each product stream.
- Specific gravity separators take out the impurities in the 2-4 and 1-2 mm.
- Fiber separator in 2-4 mm product stream takes out the fiber cord.
End Product
In the VAN AARSEN RUBBER TECHNOLOGY Process all 3-product sizes are cleaned in the FINAL CLEANER before they are bagged of in a big bag or in small bags. In this final cleaner the last pieces of impurities like dust, fibre or steel are removed to insure that the end product thoroughly clean.
Central Dust Aspiration
From several units as there are the main grinder, granulator, various sieves and the pneumatic transportation, small amounts of air is aspirated and led to the central dust aspiration.
The system separately filters out the fibers and small rubber pieces. The emission meets the European and United States standards. The central dust and fiber aspiration system is integrated throughout the system.
The Van Aarsen designed Tyre Recycling system enables our customers to recycle whole tyres in just 3 steps to commercial marketable granulates with low operational costs.
