The deposit hoppers are primarily used as a feeding system for a sorting line, a washing line or for windshifters. The deposit hoppers can be loaded by a front loader or grabber. They can be equipped with a walking floor or with a dosing conveyor belt, which is suitable for frequency control. The chosen material of the slats of the walking floor depends on the material. The conveyor belt can be supported over the total length with impact rollers to protect the belt during loading of heavy materials like demolition and construction waste.
