Overview – What Are Piano Wire Screens?

Piano wire screens—also known as high-tensile self-cleaning screens or harp wire screens —are engineered for applications where traditional woven wire mesh struggles with blinding, pegging, and clogging. 

These screens use parallel high-tensile steel wires supported by polyurethane or steel cross members, allowing the wires to vibrate independently to release fines and prevent material from getting stuck.

Compared with standard woven screens, piano wire screens deliver significantly higher open area, consistent stratification, and improved screening efficiency in wet, sticky, or fine materials.

Applications of Piano Wire Screens

Piano wire screens are widely used in the mining, aggregates, construction, recycling, and general industrial sectors, delivering excellent performance for screening wet, sticky, fine, or hard-to-process materials.
