The present invention relates to an impeller filling shoe for supplying material to a die bore of a rotary press, wherein the impeller filling shoe comprises a two-chamber filling shoe and a filling vane wheel, proportionally including a filling vane wheel and a proportional vaning wheel. Built-up to allow a functional change between a three-chamber filling shoe including a vane wheel and a supply vane wheel, the impeller filling shoe is a gear for driving the vane wheel. Does not contain a box The invention also relates to a rotary press comprising a modular impeller filling shoe, whereby a gear box for driving the vane wheel is located outside the impeller filling shoe. The invention relates to the use of the impeller filled shoe according to the invention in a method of converting a modular impeller filled shoe from a two-chamber filled shoe to a three-chamber filled shoe or vice versa. The functional conversion of the impeller filling shoe can be performed both in the mounted state outside the tablet press and inside the tablet press.
