With the JunkSeparator S, small heavy dirt particles, such as sand, glass and metals, can be reliably removed. In particular, the rejections from cleaners and high-substance cleaners are introduced here. The JunkSeparator S works on the principle of sedimentation. Particles with a higher density than water sink into a calmed pool. By installing an inclined trough conveyor, the sunken heavy dirt can be removed. The resulting water is separated from heavy dirt via an overflow.
