HOPPER SILOS

Our metal hopper silos are the optimal choice for storage and the unloading of grain by gravity.

Essential in sectors such as breweries, feed mills, port terminals, mills, bioethanol, oilseeds, dryers, flour mills, as well as storage of raw material for the plastic and biofuel industry.
