Abstract
A milling roll of a roll mill may have a roll main body and an edge element that is attached to an end region of a roll end of the milling roll and extends in a radial direction beyond a surface of the roll main body. The edge element comprises a base flange and a spacer element that is attached thereto. Wear protection elements can be attached to the spacer element. Furthermore, a roll mill may have a first milling roll and a second milling roll that are arranged opposite one another and can be driven in opposite directions. A milling gap is disposed between the milling rolls, and an edge element on one of the milling rolls may extend over the milling gap and at least partially cover an end side of the opposite milling roll.
Claims18
A milling roll of a roll mill, comprising:
- a roll main body having a milling face;
- and
- an edge element that is attached to an end region of the roll main body, wherein the edge element comprises:
- a base flange,
- a spacer element that is rigidly attached to the base flange, and
- wear protection elements that are attached to the spacer element,
- wherein the spacer element is disposed between the wear protection elements and the base flange,
- wherein the base flange, spacer element, and wear protection elements each extends in a radial direction beyond the milling face of the roll main body.
A method for setting an end-side gap of a roll mill with a first milling roll and a second milling roll that are arranged opposite one another and are configured to be driven in opposite directions, each of the first milling roll and the second milling roll having a cylindrical roll main body with a milling face, wherein a milling gap is disposed between the first and second milling rolls, wherein at each end of the milling gap an end region of one of the milling rolls has an edge element that is configured to extend over the milling gap and at least partially cover an end side of the opposing milling roll, thereby forming the end-side gap between the edge element and the end side of the respective opposite milling roll, with the edge element having a base flange, the method comprising:
- rigidly attaching a spacer element to the base flange;
- and
- attaching wear protection elements to the spacer element;
- wherein the spacer element is disposed between the wear protection elements and the base flange;
- wherein the spacer element and wear protection elements extend radially beyond the milling face of its respective milling roll.
