A conidur screen is similar to a grater hole screen, with a raised hole to create a rasp, but a conidur screen can be used to produce a smaller particle size. A conidur hole screen is made from conidur sheet, allowing it to be manufactured with a smaller hole size than is available with grater hole screens.
Similarly to a grater screen, a conidur hole screen is designed for the milling of particularly hard materials, which require a more aggressive milling action than a conventional round-hole screen. Typically these applications will require a square-bar impeller.
Typical applications for a conidur hole screen include seeds, and hard products which are trying to be reclaimed, such as tablets or sweets.
