Abstract

The invention relates to an impeller filling shoe for material feed to die bores of a rotary press, which is built-up modularly in order to enable a change in function between a 2-chamber filling shoe comprising a filling vaned wheel and a proportioning vaned wheel, and a 3-chamber filling shoe comprising a filling vaned wheel, a proportioning vaned wheel and a feeding vaned wheel, wherein the impeller filling shoe does not comprise a gearbox for driving the vaned wheels. Furthermore, the invention relates to a rotary press comprising the modular impeller filling shoe, whereby the gearbox for driving the vaned wheels is located outside the impeller filling shoe. The invention relates in addition to the use of the impeller filling shoe according to the invention in methods for converting the modular impeller filling shoe from a 2-chamber filling shoe to a 3-chamber filling shoe and vice versa. The functional conversion of the impeller filling shoe can take place both outside the tablet press as well as in the mounted state inside the tablet press.
