Eagle International, Lyons, Nebraska, has debuted the Eagle Edge 360, which is designed to produce high-quality mulch from the treads and sidewalls of over-the-road (OTR) tires ranging from 33 inches to 63 inches in rim size.
The design features rasp heads in three locations at varying angles. Multiple rasp heads increase the surface area that can be claimed as mulch and speeds up cycle time, according to the company. In addition, operators can shred rubber mulch from the tread and sidewall simultaneously.
“Our goal with this machine was to incorporate automation,” says Joe Brehmer, president of Brehmer Mfg. Inc., the parent company of Eagle International. “Once the machine has been set up, and you tell it how wide the tire tread is, the programmable logic controls (PLCs) take over.”
The Edge 360 uses semiautomation through PLCs that adjust for speed and rasp pressure, according to the company. The PCLs maximize efficiency by providing consistent pressure and tire rotation to remove mulch evenly across the whole surface of the tread. Operators also control rasp angle and depth with a remote function, Eagle International says.
The entire system includes the Edge 360, a high-efficiency vacuum, cyclone, magnet, conveyor, hopper and bag stand.
“I wanted the Edge 360 to have an element of transportability that Eagle International equipment is known for,” Brehmer says. “We designed this machine to come apart in sections so you can transport it to different locations. You can set up where the stock tires are being stored, recover your mulch and tear down to move on to the next location.”
