Industry sources predict that the tire and rubber recycling market will continue to strengthen.
Poised to respond to market demand, ECO Green Equipment recently announced the latest addition to their recycling equipment lineup – the ECO Monster – a new hydraulic powered single-shaft shredder for scrap waste tire applications. “This new technology will provide aggressive shredding capabilities to processors who demand the best efficiencies and low maintenance equipment features,” commented Brad Swenson, manager. The shredder is outfitted with a 180 kW (250 hp) custom hydraulic power unit which drives a Hagglunds motor. The ECO Monster churns through waste rubber, outputting rough shreds down to 2” to 8” inches in size. Volume production can be expected at an output of up to 12 tons per hour. It has a rotor length of 77”, which contains 18 fly knives and 9 bed knives for cutting. A hydraulic service door opens and reveals a cutting chamber containing a hefty set of cutting blades, knives, and a 32” diameter rotor. The uniquely designed knives are service friendly and can be quickly changed and rotated with a simple impact drill and torque wrench.
“This machine features the quickest blade change on a primary shredder in the industry. We’re happy to demonstrate how this shredder outputs rough shreds for TDA, TDF and further downstream processing. TDF and TDA are almost 50 percent of the total market share of annual scrap tire uses in the U.S. with high demand coming from the cement kilns, pulp and paper mills, and utility boilers. ECO Monster is positioned to help processors grow these market segments more efficiently,” said Swenson. The shredder can also process other waste materials such as wood, plastics, and electronic waste for general waste reduction, even for further processing. ECO Green is based in the U.S. but provides products to the global market.
Franklin Miller manufactures a full line of industrial and solid waste shredders. The company’s Taskmaster® TM3000 is a heavy-duty industrial shredder designed to reduce a high volume of rubber and other solid waste materials with its low speed, high torque design. The twin-shaft shredder is suitable for a variety of applications that demand high power, large throat openings and extra heavy-duty construction. Dave Schuppe, vice president, sales, described how “the design of the unit provides effective operation with low noise, sparking, dust or heat rise. Built for the highest level of performance and reliability using quality components, superior design and engineering, the TM3000 offers 5.5″ heat-treated alloy steel hexagonal shafting, 2″ cam cutters, a heavy steel plate and channel body construction and planetary gear drive. The unit can rip, tear and shred through a variety of tough solids, reducing the volume for further processing or economical disposal. It can also reduce such items as: kitchen waste, metal, steel drums, wood pallets, cardboard, and more. With cutting chambers ranging from 8.5” to 40” and up to 72” long there is a Taskmaster shredder to suit almost any application.” Franklin Miller has been a leader in size reduction for over 95 years.
“As a complete system provider, Granutech-Saturn Systems offers leading edge, best-in-class tire recycling technology in an integrated system level solution, with a wide range of custom products excelling in operating efficiency, durability, and reliability, to generate clean rubber crumb or powdered rubber,” stated Mike Hinsey, vice president. Hinsey said the company’s product options include single rotor, dual and quad industrial shredders at the simplest stage, and evolves from there to 2-stage to 3-stage and 4-stage tire recycling systems, which would additionally integrate industrial grinders and granulators, powderizers, and refiner mills. The 2-stage system reduces whole tires to steel-free mulch material or a low steel fuel quality material.
“This system solution would typically be comprised of our Saturn Shredder series – dual or quad shaft – with standard or hybrid drive systems, plus our grinder – Saturn Grizzly Series- M80 or Super80 models. The Super80 model processes more than 10 tons of tires per hour. The 3-stage system includes our 2-stage system plus a granulator or a refiner mill. If a customer needs to produce large granulate which must then be reduced to 1-6 mm material output, our Saturn G-3 Granulator would be added. For .5 to 3mm material output, we would add our Saturn G-4 Refiner Mill. A 4-stage system would reduce all material to 1 to 3mm, with the addition of a Saturn powderizer or all less than 1mm with the Saturn G-4 refiner mill,” Hinsey noted.
Dave Fleming is marketing director at SSI Shredding Systems and he explained that the company’s products, used all over the world, include one, two, three and four shaft processing machinery, capable of reducing tires of any size down to 12 mm granules. “Our in-house product development team ensures that we offer customers the highest levels of reliability, ease of maintenance and lowest operational costs possible. SSI has installations processing mixed tires at throughput rates starting at 2 tons per hour and topping out just over 30 tons per hour. Most customers are producing 2” chips or 4 to 6” materials that are used for a wide range of applications such as tires-to-energy technologies, civil engineering and crumb rubber production system feedstock. Each prospective customer has different goals. Sometimes capital cost or the physical size of a system are more important factors than operating costs or throughput, so we have systems to meet those needs. Sometimes throughput and operating costs are the only things that matter, and our expertise is well-suited for helping in those environments.”
Fleming added that most of the growth in the industry is outside of the U.S. right now, and SSI receives a high number of inquiries from companies that seek solutions for processing large sized tires. “We have developed a new machine to downsize these large tires to 100 – 150 mm (4 – 6”) sizes while also reducing the thickness of the output materials to a point where conventional tire processing machinery can accept it and reduce it further. Due to the quality of rubber found in these large tires, most customers are looking to make ‘wire free’ materials that are 12 mm to 25 mm from OTRs. Our single-rotor machinery is an ideal secondary processor for this application,” Fleming said.
