We are specialists in sieves or screens for mills

In hammer mills, grinding, the grain size variation of the finished products, is determined by the diameter of the hole in the screen, or screen, or perforated sheet metal.

Molinos Vieira specializes in the manufacture of perforated sheets or screens or conical hole screens.

These are developed with perforations from 0.3 mm and are manufactured in sheets with thickness thicker than the diameter of the holes, which allows more durability in terms of wear and abrasion during grinding.
