  • Patent number: 10022899
    Abstract: A double belt press having a first, lower circulating plastic belt and a second, upper circulating plastic belt. The plastic belts have a first, low flexural strength, and a product gap is formed between facing strands of the plastic belts for forming a plate-like product. A first circulating lower steel belt and a second circulating upper steel belt are provided and have a second flexural strength which is high in comparison to the flexural strength of the plastic belts. A forming section is formed between the facing strands of the steel belts, which forms part of the product gap. The first, lower steel belt runs parallel and bears against a rear face of the first plastic belt in the forming section during operation, and the second upper steel belt runs parallel and bears against a rear face of the second plastic belt in the forming section during operation.

  • Publication number: 20070131381
    Abstract: 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.
