20130075510 | PULPER HAVING A SUPPLY CHAMBER AND A DISPLACEMENT CHAMBER - The invention relates to a pulper comprising a supply chamber ( | 03-28-2013 |
20130206881 | PULPER COMPRISING A SCREENING SHEET - An individual pulper is used and fibrous material is removed from the pulper in an optimum manner. In order to do this, the screening sheet of a pulper has openings which are disposed in various regions and have different sizes. The regions are concentric to each other. | 08-15-2013 |
20130221140 | METHOD FOR PROCESSING BIOMASS - The invention relates to a method for processing biomass, such as in particular green waste containing wood, and a high density pulper having a spiral, wherein the green waste is treated in a continuously operated, bladed pulper and then the separated fibers are ground in a pulper ball mill. | 08-29-2013 |
20140151473 | PULPER WITH A SHAFT AND METHOD FOR PROCESSING COMPOSITE MATERIALS - A pulper with a shaft on which a spiral is arranged has been improved to such an extent that it comprises a shaft with a counter-rotating spiral. Preferably both spirals are arranged on the same shaft. This results in extreme friction in the centre of the reaction space of the pulper and thus in an increase in the capacity of the pulper and in an improvement to achieve highly efficient suspension. | 06-05-2014 |
