Air density separators

The Zig-Zag air density separators are designed to separate bulky metal pieces from light inert materials such as fabrics and plastics. Processing is performed by means of air jets which ensure perfect cleaning and recovery of the output materials. The Zig-Zag range of metal air density separators is available in various models, which can be selected according to the processing flow, the outputs of the grinding plant and the sorting quality to be obtained.
