Köppern Roller Presses - Maschinenfabrik Köppern

The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the material being processed and the preset "zero-position" of the roller gap.
