Feed silo is a storage bin used to store feedstock in industrial systems such as the creation of steam power. In agriculture, feed silos are applied for large-scale animal feed or grain storage. In general, feed silos are able to store both granular and liquid materials. In most cases, feed silos are elevated above the level of the system it is used to feed, so that the force of gravity is used for moving the feedstock into the system. Feed storage bins have a level indicator or a other access point to monitor the condition of the feedstock inside. If levels get too low, the operators can add more feedstock through a valve on the top of the bin.

►A. Agricultural Feed Silo
Agricultural feed silos are ideal storage solutions for animal feed and grain. When open the valve, the feedstock can drain into the transportation device such as a truck. Agricultural feed silos are generally made of steel or stainless steel to ensure the strength and makes the silo more suitable for long term storage.
►B. Chemical Feed Silo
Chemical feed silos are specially designed to store chemicals for water treatment, Chlorine storage bin for example. Chemical feed silos are generally made of polyethylene since metal silos may react with the chemicals.
►C. Water Feed Silo
Water feed silos are used for liquid storage in many systems and steam power plant is one of the common applications.
