To prepare certain bulk materials such as sand or gravel, the industry uses screening. They separate the different rock sizes on multiple screen decks one layered on the other.
In many of these machines, the Mesh Wires are made of steel wire from the house of Gustav Wolf. Superior quality is all important, because the screens are not only exposed to heavy hard rock, but also extreme weather conditions such as heat, rain and frost.
Wires used by screen manufacturers are from 0.3 to 7 millimeters. There they are placed in a waveform, and then clamped together. Finally, the mesh in the different screen frames is welded.
