The invention relates to a feed device (200) for a high- pressure roller press (100) for the high-pressure communinution of materi-al to be ground (104), said feed device feeding the material to be ground (104) in a controlled manner into the roller nip (103) between two rollers (101, 102) of the high-pressure roller press (100). According to the inven- tion, the feed device (200) has at least two rotary valves (230, 231), the position of which is variable independently of each other. In a refinement of the invention, the feed device (200) also has a shaft (202) which is va- riable in height above the roller nip (103). By means of the rotary valves (230, 231) which are variable independently of each other and by means of the height-variable shaft (202), the feeding behaviour of the feed device (200) can be varied during the starting of the high-pressure roller press (100) and during the operation of the high-pressure roller press (100) in order thereby to prevent the high-pressure roller press (100) from vibra-ting and to ensure optimum operation of the high-pressure roller press (100).
Linvention concerne un dispositif dalimentation (200) pour une presse à rouleaux haute pression (100) qui est destinée au broyage à haute pression de matière à broyer (104) et qui charge la matière à broyer (104) de manière contrôlée dans lespace (103) entre deux cylindres (101, 102) de la presse à rouleaux haute pression (100). Linvention prévoit que le dispositif dalimentation (200) présente au moins deux tiroirs rotatifs (230, 231), dont les positions peuvent être modifiées indépendamment lune de lautre. Selon un aspect de linvention, le dispositif dalimentation (200) présente en outre un puits (202) dont la hauteur est variable dans lespace entre les cylindres (103). Grâce aux tiroirs rotatifs (230, 231) variables indépendamment lun de lautre et au puits (202) à hauteur variable, létat dalimentation du dispositif dalimentation (200) peut être modifié au démarrage de la presse à rouleaux haute pression (100) et lors de son fonctionnement, afin déviter des vibrations de la presse à rouleaux haute pression (100) et den garantir le fonctionnement optimal.
