Rheinkalk GmbH commissioned Silobau Thorwestern with the construction of a new silo installation in March 2015, in order to secure the fuel supply for the rotary kilns used for the production of quicklime in its Flandersbach plant. The large-capacity silo will be put into operation according to schedule, after a planning and construction period of about a year.

Thus far, the four rotary kilns used for limestone refining in Europe’s largest lime plant have been heated with quicklime from two large-capacity silos. To secure a consistent fuel supply for the future, the company decided to install another storage and dosing system. In march 2016, a third silo will therefore be put into operation, equipped with the latest technology in regard to level measuring, filling, discharge and explosion protection. The operating company, Rheinkalk, chose Silobau Thorwestern as its supplier as it specialises in the field of silo building for potentially explosive materials. For instance, the silo, which is over 42 m tall, has an explosion pressure shock resistant design and is equipped with ATEX-conform explosion vents and de-dusting filters from their associate company Thorwesten Vent, in order to guarantee maximum security while handling combustible pulverised coal.

The scope of supply for this 1.100 m³ large-capacity silo also includes a discharging station for silo trucks which can convey the material pneumatically by rotary piston fan via the silo roof in very short time. A highly efficient dust collector guarantees a clean filling process. Furthermore the new silo has a modern, continuous weighing system with weighing cells and separately controllable fluidisation devices on two silo outlets. These installations allow a failure-free feeding of combustible material into the dosing system. For the circulation operation there is also a duct protected by a shut-off valve.

Alongside planning and delivery of the main and sub-systems of the new silo, Silobau Thorwestern is also managing the design and erection of the entire steel construction, as well as the integration of the components into the existing process chain.
