Stator part of an impact mill and attachment method

An impact mill including a stator part attached to an inner surface of an impact mill housing wall, the stator part comprising a plurality of multifunctional stator tools, which are indirectly detachably attached to the impact mill housing wall, distributed along the inner surface, wherein the stator tools are spaced a defined distance apart from an opposing plurality of rotor tool blades of a rotatable rotor part inside of the impact mill housing and are operatively connected with the rotor tool blades, thereby forming a grinding chamber therebetween,

• wherein the stator part comprises at least one spring element with spring element recesses, wherein the at least one spring element is circumferentially attached along an inner circumference of the impact mill housing, and wherein the stator part has an upper retaining plate designed as an annular plate with a plurality of stator tool recesses facing the at least one spring element and a lower retaining plate on a side lying opposite the at least one spring element inside of the impact mill housing with a plurality of stator tool recesses, so that stator tools in the spring element recesses of the at least one spring element and the stator tool recesses in the upper retaining plate and lower retaining plate are kept detachably and replaceably stored inside of the impact mill housing.
