A self-unloading steel or reinforced-concrete (occasionally wooden) receptacle (container, coffer, or bin) for the bulk storage of granulated or lumpy materials such as grain, sand, cement, coke, coal, or ore. To permit gravity unloading, the lower portion of a bunker is built with inclined walls (for example, in the form of inverted truncated cones or pyramids). There are also doors and conveyors in the lower part to control discharge of the material. The modern bunker is a highly automated unit having centralized control for loading and unloading and for monitoring filling, discharge, and the level of stored material with programmed control. “Bunker” is also the name for magazine equipment that feeds workpieces to automated lines and for the containers on certain machines, such as reapers.
