Piano Wire Screen – No Blinding and Plugging

Piano wire screen, also known as harp wire screen, is a specialized screen structure composed of high-tensile steel wires tightly tensioned in parallel. Named for its resemblance to piano strings, it offers a higher open area and outstanding self-cleaning performance, effectively reducing material clogging and enhancing screening efficiency. This makes it particularly suitable for the screening of fine, wet, sticky, or easily clogged materials.

We offer customizable piano wire screens tailored to client requirements, with various wire diameters, aperture sizes, and edge connection methods, ensuring compatibility with different models of vibrating screen equipment.

TYPE R

Sliding patches for fixing on the riddles of the sifters, where the bearing bars constitute the cylinders.

Features

Slot-shaped meshes ensure a maximum open area of the screen.
Independent vibration of the wires that create a mesh provide a self-cleaning effect.
Patches made of wear-resistant material ensure an extended operation time of the screen.
Have the most open area of any screen type.
Increases throughput over other types of screen.
Able to screen fine soils, sand, coal and also lime.

Applications

Screening of difficult-to-screen materials with high humidity and low flowability.
