The Effect of Hammermill Screen Hole Diameter and Hammer ...

Increasing hammer tip speed increased (linear, P < 0.001) AoR. Increasing screen hole diameter decreased (linear, P < 0.001) AoR. In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible using motor variable frequency drives.

Mill SCREENS – Lestoque

The LST 60° CONIC HOLES screen surface is similar to that of a "cheese grater".This unique type of raised and inclined conic hole creates a cutting rasp that reduces the milled product in smaller particle sizes. Therefore, our screens provide hammer mills with a more aggressive pulverization action, compared with that of a conventional circular hole screen type.
