North Aurora, Ill.-based recycler Winco Plastics has boosted its plastics waste handling capabilities with a re-grinding line from Lindner Recyclingtech America LLC.
The re-grinding line includes a Micromat Plus 2500 pre-shredding system and an LG 1500-800 grinder.
The range of rigid materials the company feeds into the Lindner system includes high density polyethylene pipes of any size and thickness, HDPE sheet, polyethylene and polypropylene purge, plus polycarbonate sheet and PET, mainly from post-industrial sources such as automotive market and other markets.
Winco can run 4,000 to 6,000 pounds of half-inch regrind material per hour.
“One major reason for our decision to purchase Lindner's regrinding line was its ability to handle the wide variety of size, weight and form of the expected input material coming from different suppliers,” said Winco President Tim Martin in a news release.
Lindner Recyclingtech America in Statesville, N.C., is the North American subsidiary of Lindner-Group of Spittal, Austria.
In the first step of its process, plastic waste gets transferred to a heavy-duty feeding belt conveyor designed to handle all kinds of material loaded by a forklift or gaylord container, followed by a Micromat Plus 255 single-shaft shredder with a customized internal ram. A new overlapping rotor avoids bridging of material between the ram and the robot
The pre-shredded material is discharged from the Micromat by two successive belt conveyors. One of them is equipped with a gaylord for any scrap that is suitable for direct feeding into the downstream HP LG 1500-800 grinder without pre-shredding.
The grinder has a large feed opening of 61.5 inches by 31.5 inches, and a 98-inch long rotor with a diameter of 25 inches that carries seven knives and two counter-knives. That makes it able to recover heavy and bulky rigid scrap as well as do second-step grinding of pre-shredded material with high output rates, according to Lindner.
