LST 60°

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. We carry out periodic comparative tests that record an average decrease in grain size of 18% and an increase in output of 70%. The pronounced roughness of the holes ridges also minimize the tendency to clogging and, consequently, the maintenance stops. Thanks to the greater milling efficiency, we also obtain a significant drop in the mill’s energy consumption. Typical applications for our 60° inclined holes include pet-food, wood and and pharmaceutical tablets. Our technicians support customers throughout the development and assembly phase of the LST screens on the mills.
