An important aspect in the handling of bulk material is the most accurate way of dosing. In most cases as a discharge element of a bunker or silo, a belt conveyor, a chain conveyor or an apron conveyor ensures a dosing process with regard to the weight and volume of the bulk material to be transported, depending on the application.

These devices are used in modified versions not only in surface and underground mining facilities but also in the steel and metallurgical industry as well as in power plant technology.
