The SR600F and SR900F grow SSI’s product capabilities from traditional slow-speed shredding to medium-speed finishing. By utilizing optimized cutter geometry, and multiple cutting opportunities per revolution, these machines maximize efficiency and throughput, allowing operators to upgrade the value of their finished products through superior liberation and sizing.
“We have stand-alone shredders for compressible waste and grinders designed to liberate commingled materials, and now finishers to size preconditioned material and achieve very high- quality levels,” said Dave Fleming, Vice President of Sales and Marketing at SSI. “These machines provide the final sizing step for many types of material and make highly marketable commodities.”
The development of the “F” series was driven by customer demand for a U.S.-based supplier capable of providing complete, end-to-end size reduction systems. Ideal applications for the new finishers include insulated copper wire, radiators, tire rubber, plastics, paper, and Refuse Derived Fuels (RDF). Depending on the material and screen size (ranging from 4mm to 50mm), the units can achieve throughput rates between 2 and 25 tons per hour.
Lee Sage, Industrial Sales Specialist at SSI, noted that the addition of these models allows SSI to serve markets with tighter specifications. “It completes the sizing line for SSI,” Sage said. “For the tire application, we can now offer whole tire processing down to crumb rubber.”
A primary focus of the design was addressing the struggle of downtime that many operators experience with these forms of industrial equipment. To solve this, SSI engineers reduced the number of tools required for regular service to just two or three. Key features include the ability to adjust cutter-to-anvil gaps while the machine is running and a screen changeover process that takes less than 15 minutes.
“The ease of maintenance is what separates us from the competition,” said SSI’s Senior Engineer Paul Breithaupt. “We have now developed these medium-speed single rotor machines to blend SSI’s known durability and maintenance cost reduction while still achieving a small output size.”
The finishers are built with the heavy-duty DNA SSI is known for, featuring specific wear liners and internal features to protect critical parts when processing tough materials. The machines are also designed for modern plant layouts, with testing results proving the effectiveness of clean, versatile pneumatic air conveyance for material discharge.
“It really closes the loop to allow for a total sizing system in a lot of the markets we are already active in,” said Nathan Wilt, Technical Sales at SSI. “It also gives us the flexibility to tailor the right type of equipment to the customer’s goals and not trying to shoe-horn something in that isn’t optimized for the application.”
With the launch of the SR600F and SR900F, SSI Shredding Systems now offers a comprehensive range of machinery, from large Dual-Shears® capable of handling whole OTR tires to finishers producing 4mm particles, all supported by a single source.
