RTI’s first turnkey solution is a Primary cryogenic tire recycling system, which can be a standalone tire recycling system.
An RTI Primary system produces 99.9% pure rubber crumb up to 30- mesh.
The whole tire is shredded and then granulated to approximately 3/4 inch/1.5 cm size. The shred is conveyed to a Freeze Chamber where it is pre-cooled as it enters through an air lock at the front end and conveyed to the exit end. At the exit end, liquid nitrogen is applied to the shred which freezes the rubber past its glass transition temperature of approximately -80° C . The frozen rubber shred is then pulverized in our Hammer Mills which have a very high hammer tip speed.
The frozen rubber crumb is then conveyed to a screener where the fibre is scalped off while larger pieces of crumb are returned to the freeze chamber. The smaller crumb is then dried.
The first removal of steel from the line is by a rare earth magnet and then the crumb is screened to select as many sizes as desired in a standalone system. There is a second rare earth double drum magnet further on in the line before the material gets classified into your desired sizes.
RTI’s Primary system provides the highest gross margin per dollar invested when compared to any tire recycling system that can produce the same volume and same mix of outputs.
The Primary cryogenic tire recycling plant has a capacity to process 500 car tires per hour or 2.5 million tires per year operating 5 days per week, or 3.5 million tires if operating 7 days per week
There is no effluent so environmental permitting is very straightforward.
RTI’s Primary system is truly the “Zero Pollution Solution“
All components of the Primary tire recycling solution are manufactured by third party contractors according to RTI drawings and specifications. RTI receives, ships, assembles and installs these components at the customer’s facility and then trains the manager and operators, and commissions the system to provide a complete turnkey solution.
A system Performance Protocol has to be signed by the customer before RTI receives its final payment.
Cryo crumb demands a premium in the marketplace and is the favourite type of crumb rubber used in the sports field market.
30- cryo crumb rubber is used in rubber asphalt.
A properly maintained RTI cryo plant has a useful life of 12 – 15 years or more as evidenced by the first plant that was established in Cambridge 1n 1993.
RTI’s Primary system is designed to be integrated with a secondary cryogenic process, our value-added Fine Mesh solution. When integrated with the Fine Mesh system, the 30+ stream is sent directly to the Fine Mesh system.
