HAAHJEM® SWS 2000 - Stone-Wood-Separator, is a sorting unit that is based on the different densities of materials as a separation method.
Water is used as the base medium, after which materials with higher or lower density are separated.
Kalibrert materiale mates inn hvor ideelt sett alt av fraksjon < ÷10 mm er fjernet. "Tungt" materiale synker - og "lett" flyter. Materiale forflyttes fra overflaten til den ene siden, og det som synker til andre siden.
If the material is pre-treated by crushing, metal can be removed via a belt magnet placed on the feed station. In addition to this, a wind screen can be mounted to remove plastic and "light" materials.
