Precision right down the line: Wirtgen cold milling machines not only create an even base for new asphalt pavements that is true to cross-section line and level. They also contribute to the highly economical recycling of milled material in asphalt mixing plants.
During the milling process, fine material particles and water vapor are produced in the milling drum aggregate. The Vacuum Cutting System applies negative pressure to suck the particles and water vapor into the milling machine’s short conveyor channel directly at the milling unit, which is additionally sealed. A suction hood located above the conveyor channel draws the particles into two hoses that lead directly to the long conveyor of the loading system.
Selective milling: With the help of modern machine technology, the surface, binder and base courses can be removed separately and also returned to the material cycle separately. This increases the sustainability of RAP recycling.
“The WIRTGEN Vacuum Cutting System is a clean solution and ensures the best visibility con-ditions.” Kazunari Watanabe, Milling Machine Operator Unite Co., Ltd.
