Coal silos are often used in areas where space is scarce, or because of environmental issues. Enclosed storage reduces the impact on the environment. If enclosed storage is used, different properties are important. The material characteristics can be split up in basic properties (moisture, angle of repose, etc.) and physical properties (shape, size, density, etc.). Different equipment is used to handle coal, conveyors are specifically used in enclosed storage. The current system with an infeed rate of 2,500 MTPH is fully developed. Higher infeed rates are required due to rising industries, larger vessels and cranes. A new system has to be found to combine high infeed rates with enclosed storage. Different concepts are developed, from which one concept is developed detailed. Different situations are used to compare filling multiple silos relative to each other and the comparison is made between vessel unloading and silo loading.
