MASS DISCHARGE SILOS
Mass discharge is a type of discharge in which virtually all of the product in the silo is in motion.
This movement of all the grain at the same time causes high stresses in the silo walls which require a calculation according to EUROCODIGO 1.4 -4 considering an eccentric discharge.
