The larger open screen area of a rectangular wire mesh has a decisive advantage: A higher performance with less tendency to clog.
If the long slot runs parallel to the material flow, you achieve a higher throughput – if it runs perpendicular to the flow, you achieve a more precise cut. The bigger the length-to-width ratio, the more flexible the wire mesh and the better the self-cleaning effect.
Most rectangular meshes have a standard aspect ratio of 1:3, while the wire diameter remains identical to the corresponding square mesh. The open area is therefore increased ensuring a higher throughput.
