Germany: Rheinkalk GmbH has commissioned Silobau Thorwesten to supply a large capacity silo to its Flandersbach lime plant. The silo was originally commissioned in March 2015 and is due to become operational in March 2016. The 42m silo has an explosion pressure shock resistant design and is equipped with ATEX-conform explosion vents and de-dusting filters from associate company Thorwesten Vent to handle combustible pulverised coal.

The scope of supply for this 1100m³ capacity silo also includes a discharging station for silo trucks which can convey the material pneumatically by rotary piston fan via the silo roof. A dust collector assists the filling process. Additionally, the new silo has a continuous weighing system with weighing cells and separately controllable fluidisation devices on two silo outlets. These installations help feed combustible material into the dosing system. For the circulation operation there is also a duct protected by a shut-off valve.

Besides planning and delivery of the main and sub-systems of the new silo, Silobau Thorwesten also handled the design and erection of the entire steel constructions, as well as the integration of the components into the existing process chain.
