Tabletting system

A method for continuous production of tablets, the method comprising:

• providing a rotary tablet press with a plurality of dies, a top punch, a bottom punch, and a tablet press feeder;
• providing at least one first material feeder with an inlet and a discharge end;
• providing at least one second material feeder with an inlet and a discharge end;
• providing a blender with an inlet end and a discharge end, wherein the blender is positioned in close connection with the tablet press;
• connecting the inlet of the blender to the discharge ends of the first and second material feeders;
• connecting the discharge end of the blender to the tablet press feeder;
• feeding a first material having a first predefined mean particle size to the first material feeder;
• feeding a second material containing particles having a second pre-defined mean particle size significantly different from the first material to the second material feeder;
• mixing the first material with the second material in the blender while transporting the mixed material stream substantially vertically from an upper level to a lower level;
• feeding the mixed material stream from the discharge end of the blender to the tablet press, and
• tabletting the mixed material stream in the tablet press.

A system comprising:

• a rotary tablet press comprising a plurality of dies, a top punch, a bottom punch, and a tablet press feeder;
• at least one first material feeder with an inlet and a discharge end;
• at least one second material feeder with an inlet and a discharge end;
• a blender with an inlet end and a discharge end, the inlet of the blender being connected to the discharge ends of the first and second material feeders, and the discharge end of the blender being connected to the tablet press feeder, wherein the inlet end of the blender is positioned at a level higher than the level of the discharge end of the blender in the vertical direction, and that the blender is positioned in close connection with the tablet press.
