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.
