Self-Cleaning Screens & Piano Wires

Self cleaning screens, prevent clogging or binding in very difficult conditions. Screens are made up of crimped and straight wires connected by cross wires at regular intervals. The different wires vibrate independently of each other helping to avoid clogging or binding.

Piano wire screens give very good performance with regard to throughput and binding. These types of screens are generally supplied for smaller screen sizes where wet sticky conditions exist.

Self-cleaning Screens

Are manufactured using crimped or crimped and straight wires that are connected at few intervals along the screen, this enables the wires to vibrate independently and are therefore suitable for screening irregular shaped material.

Piano Wire Screens

Are made using straight parallel wires that are connected at few intervals along the screen giving a large elongated opening. This is useful for screening regular shaped material and makes for a more open screen with very high output.
