Publication number: 20070131381Abstract: Method for belt conditioning in pelletizing plants, method for pelletizing urea and pelletizing plant. The invention relates to a method for belt conditioning in pelletizing plants with a rotating steel belt to which is applied in drop-like manner a melt of a product to be pelletized which is then solidified on the steel belt. According to the invention there are steps of washing off product residues left on the steel belt after removing the solidified pellets using a washing liquid containing at least the dissolved product and drying the washing liquid adhering to the steel belt for forming a dry product film thereon prior to the renewed application of a melt of a product to be pelletized. Use e.g. for pelletizing urea.Type: ApplicationFiled: November 6, 2006Publication date: June 14, 2007Inventors: Konrad Schermutzki, Hans-Kurt Schromm
