Abstract
The invention relates to a replaceable key grinding pan segment for a grinding track of a grinding pan of a roller mill, the grinding track having an annular shape with an outer circumference and an inner circumference around a center point. The length of the inner edge of the key grinding pan segment closer to the center point is greater here than the length of the outer edge further from the center point. The invention also relates to a grinding pan segment system, a roller mill, and a method for replacing grinding pan segments.
Claims12
A grinding pan segment system for a grinding track of a grinding pan of a roller mill comprising multiple grinding pan segments each having an inner edge and an outer edge, which are connected by two connection edges,
- wherein the length of the inner edge is smaller than the length of the outer edge, at least one exchangeable key grinding pan segment for the grinding track of the grinding pan of the roller mill,
- wherein the grinding track has an annular shape with an outer circumference and a smaller inner circumference around the center point,
- and having at least one compensating grinding pan segment which is arranged next to the key grinding pan segment,
- wherein the length of a circular arc formed by the key grinding pan segment decreases as the radius from the inner edge to the outer edge increases, whereby the shape of the key grinding pan segment is a shape similar to an inverted piece of cake,
- wherein the grinding pan segments are formed as standard grinding pan segments of the same size and shape, and in that the key grinding pan segment and the at least one compensating grinding pan segment together form the shape of one or more standard grinding pan segments.
