Abstract
A filling apparatus comprises a filling material reservoir and a filling chamber that is connected to the filling material reservoir with a filling opening configured to dispense filling material into cavities in the rotary press. A first rotatably driven stirrer blade wheel with one or more stirrer blades and a second rotatably driven stirrer blade wheel with one or more stirrer blades are arranged in the filling chamber. The first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the second rotatably driven stirrer blade wheel.
Claims14
A filling apparatus for filling cavities in a rotary press, the filling apparatus comprising:
- a filling material reservoir;
- a filling chamber connected to the filling material reservoir and having a filling opening configured to allow filling material to pass through;
- a first rotatably driven stirrer blade wheel having at least one stirrer blade;
- and
- a second rotatably driven stirrer blade wheel having at least one stirrer blade;
- wherein the first rotatably driven stirrer blade wheel and the second rotatably driven stirrer blade wheel are disposed in the filling chamber, and wherein the at least one stirrer blade of the first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the at least one stirrer blade of the second rotatably driven stirrer blade wheel.
A rotary press comprising;
- a rotor configured to be rotated by means of a rotary drive, the rotor comprising,
- an upper punch guide for upper press punches,
- a lower punch guide for lower press punches, and
- a die plate disposed between the upper punch guide and the lower punch guide, the die plate having a plurality of cavities, wherein the upper press punches and the lower press punches are configured to interact with the plurality of cavities in the die plate,
- a filling apparatus configured to house filling material and dispense the filling material into the plurality of cavities in the die plate;
- at least one upper pressing apparatus and at least one lower pressing apparatus configured to interact with the upper press punches and the lower press punches to press the filling material into the plurality of cavities in the die plate to form pellets;
- and
- an ejection apparatus configured to eject the pellets from the plurality of cavities.
