Granutech-Saturn Systems launches next generation refiner mill for crumb rubber
‘Grease-free’ sealed roller bearing design runs cooler and more efficiently, and eliminates grease pump and lubricant expense
Granutech-Saturn Systems, manufacturer of the Saturn brand of industrial and mobile shredders, has announced the launch of a revolutionary new design for the company's refiner mill for scrap rubber, featuring sealed roller bearings for greater tolerances in processing material down to 80 mesh. The G4X, is a next generation product to the company’s popular G4 mill, but features a completely unique sealed roller bearing design, that provides significant benefits over the industry’s traditional bushing design mills.
“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. “In addition, the ‘sealed’ barrel design eliminates the need for continuous lubricant, resulting in significant operational & consumables savings,” he added.
In fact, one of the company’s tire recycling clients, 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."
According to Granutech-Saturn, the new design enables the G4X mill the ability to hold the rolls at much closer tolerances (up to 400% closer than traditional bushing designs), which translates to finer cleaner usable powder and fewer processing cycles, which translates to higher production. And with reduced roll clearances in roller bearing design, there is an increase in processing capacity as well, translating to a throughput of asphalt quality crumb rubber of 3 tons per hour (up to 25% higher than leading mills).
The Saturn G4X mill is ideal for efficient production of fine granulate powder for applications such as rubberized asphalt and molded product or filler materials.
