Abstract
An enhanced operating comfort is to be achieved in a rotor part of an impact mill with a plurality of rotor tool blades detachably attachable to a blade attachment plate. This is achieved by recessing a spacer recess out of each rotor tool blade, recessing a blade holding recess and a plate spacer recess out of the blade attachment plate at each blade position, and having one spacer per rotor tool blade that can be held rotatably in the spacer recess and fixed in the plate spacer recess. An impact bead is arranged circumferentially at the upper edge of spacer, and each blade holder fixes a rotor tool blade to the blade attachment plate, and hence interacts with the spacer to prevent a movement by the rotor tool blade parallel and perpendicular to the longitudinal axis.
Claims10
A rotor part of an impact mill, wherein the rotor part comprising a plurality of rotor tool blades that can be detachably attached to a blade attachment plate, wherein each rotor tool blade can be detachably attached to an allocated blade position with a blade holder, and the entire rotor part is configured to be rotatably mounted around a longitudinal axis by means of a rotor part attachment sleeve attached to a drive in an impact mill housing at a defined radial distance to a stator part with a plurality of stator tools,
- wherein a spacer recess is recessed into each rotor tool blade, a blade holding recess and a plate spacer recess is recessed into blade attachment plate at each blade position, and a spacer per rotor tool blade can be rotatably mounted in the spacer recess and fixed in the plate spacer recess,
- wherein a circumferential impact bead is arranged at the upper edge of the spacer, and each blade holder fixes a rotor tool blade to the blade attachment plate, and hence interacts with the spacer to prevent a movement by the rotor tool blade parallel and perpendicular to the longitudinal axis.
A method for adjusting the distance between a rotor tool blade detachably attached to a blade attachment plate of a rotor part of an impact mill relative to a stator part fixedly arranged on an inner surface of an impact mill housing or stator tools of the stator part, the method comprising:
- I detaching a blade holder from the rotor tool blade,
- II lifting up the rotor tool blade with a spacer out of a blade holding recess and a plate spacer recess in the blade attachment plate, and then
- III rotating the spacer, so that another recess of the spacer faces toward the side lying opposite the tip of the rotor tool blade, and the rotor tool blade with the spacer is thereby held indirectly and introduced back into the blade holding recess and the plate spacer recess, and again fixed to the blade attachment plate by means of the blade holder.
