Harp screens
Harp screens
Maximum performance under all conditions
They are a specific type of screens used mainly for screening difficult-to-screen, especially wet and abrasive materials. The construction of the harp sieve is designed in such a way that the longer wires are clamped to each other at a relatively large distance by a transverse bond, which ensures that besides screening machine vibrations, the screen itself produces its own dissonant frequency, which counteracts sticking and clogging of the screen meshes.
Harp screens are supplied exclusively with tensioning folds, which are necessary for the correct operation of the screen. The screens are supplied with wire or polyurethane braids, which further increase the lifetime and efficiency of the screens. When ordering harp nets, we recommend you to choose a mesh size that is 10% smaller than that of wire screen with rectangular meshes.
