Title: Heinrich Rotger: Innovator in Phosphate Fertilizer Production
Introduction
Heinrich Rotger is a notable inventor based in Ronnenberg, Germany. He has made significant contributions to the field of phosphate fertilizer production, holding 2 patents that showcase his innovative processes. His work focuses on high-temperature decomposition methods that enhance the solubility of calcined phosphates.
Latest Patents
Rotger's latest patents include a high-temperature decomposition process for producing alkali-containing highly citrate soluble calcined phosphate fertilizer. This process involves calcining a preheated mixture of crude phosphate, an alkaline decomposing agent, silicic acid, and phosphoric acid in a rotary kiln at temperatures ranging from 900°C to 1300°C. The innovative method allows for the direct introduction of phosphoric acid into the kiln, ensuring optimal contact with the hot precursor mixture.
Another significant patent details the process for making calcined alkali phosphates of high citrate solubility. This method subjects natural calcium phosphates, including tricalcium phosphate, to thermal decomposition with an aqueous alkali hydroxide solution in a revolving furnace. The process is designed to achieve rapid evaporation of water and efficient homogenization, resulting in high-quality calcined alkali phosphates.
