It is a perfect solution where charging and discharging occur frequently. Easy discharging is the advantage of the hopper bottom. They are delivered with a 37˚, 40˚, 45˚or 60˚ degree hopper bottom, which depends on the consistency of the products storing in the silo (the thickness of the zinc is 600g/m2). Using commercial hopper silos accumulation can be avoided, and using work force and energy can be reduced during storing. Additionally, with this construction discharging can be quick and simple.
