Round Hole Screens
Round hole screens are used in most cone-milling applications. Typically used for the size reduction of free-flowing materials such as granules, small lumps and powders can be easily milled through the round hole screen. A wide range of screen meshes are available, in different size and with different apertures.
Grater Hole Screens
The surface of the grater screen will create a shearing action for breaking up the material. Typical applications for a grater screen include seeds, and hard products which are trying to be reclaimed, such as tablets or sweets. Failure to correctly identify the need for a grater screen can result in the generation of more fines or can severely damage the screen.
Square Hole Screens
Large aperture ‘square’ hole screens are mainly used for coarse milling applications such as deagglomeration of fruits or for producing flakes of material. The square hole screen is also suitable for wet-milling (moist) applications such as de-lumping of wet mass granulation in pharmaceutical processing.
