Granutech-Saturn Systems, manufacturer of the Saturn brand of industrial and mobile tyre shredders, has launched a new refiner mill. The machine features sealed roller bearings for greater tolerances in processing material down to 80 mesh. The company will bring its latest machine to Reifen 2016 (Hall GA- Stand 114), where visitors can learn more about the new machine and the company’s complete tyre recycling systems.
The G4X is the next generation product to the company’s existing G4 mill. It has a completely new sealed roller bearing design that, the manufacturer states, provides significant benefits over the industry’s traditional bushing design mills. The design enables the G4X mill the ability to hold the rolls at much closer tolerances (up to 400 per cent closer than traditional bushing designs), which translates to finer, cleaner, more usable powder and fewer processing cycles, which in turn means higher production. With reduced roll clearances in roller bearing design there is also an increase in processing capacity, translating to a throughput of asphalt-quality crumb rubber of three tons per hour; a figure Grauntech-Saturn claims is up to 25 per cent higher than leading mills.
“In addition, reduced bearing temperature means this design runs cooler and more efficiently than traditional bushing design competitive mills, resulting in less energy used for external cooling,” said Mike Hinsey, Granutech-Saturn Systems vice president. “The ‘sealed’ bearing design eliminates the need for continuous lubricant, resulting in significant operational & consumables savings.”
One of the company’s tyre recycling clients in the US, State Rubber, was a key contributor in the development of the spec for the new product “Granutech-Saturn clearly paid attention to our inputs, and created a next generation design that met all the requirements. We are thrilled with the new G4X mill,” said Jerry Woosley, president of State Rubber. “The savings in lubricant alone, averages $25,000 a month, and we also noticed a more consistent and cleaner output of crumb rubber granulate, due to the tighter tolerances achieved by the new rolls.”
Grauntech-Saturn says the new G4X mill is ideal for the efficient production of the fine granulate powder used in applications such as rubberized asphalt and molded product or filler materials.
