Abstract
A system for a vertical grinding mill. The system includes a longitudinally extending shaft supporting a helical screw flight and at least one adaptor plate configured to be fixedly mounted to the shaft. Each adaptor plate includes at least one first locking member. The system further includes at least one wear segment configured to be supported by the at least one first locking member. Further, a replacement kit, a kit of wear protection elements and a vertical grinding mill is provided.
Claims14
A system for a vertical grinding mill, the system comprising:
- a longitudinally extending shaft supporting a helical screw flight,
- a plurality of adaptor plates configured to be fixedly mounted to the shaft, each adaptor plate including at least one first locking member;
- and
- a plurality of wear segments, each of the plurality of wear segments including a second locking member, wherein the second locking member of each of the plurality of wear segments is configured to engage the first locking member of one of the plurality of adapter plates such that the plurality of wear segments are supported by the plurality of adapter plates,
- wherein the plurality of wear segments are configured to be arranged adjacent to each other as seen along the longitudinal extension of the shaft in an abutting relationship and/or in a partly overlapping relationship.
A replacement kit of wear segments for a longitudinally extending shaft supporting a helical screw flight and a plurality of adaptor plates each having a first locking member, the replacement kit comprising a plurality of wear segments each configured to be supported on the shaft by the plurality of adaptor plates, wherein the plurality of wear segments are configured to be arranged adjacent to each other as seen along the longitudinal extension of the shaft in an abutting relationship and/or in a partly overlapping relationship and wherein each of the plurality of wear segments comprises
- a second locking member having a geometry complementary to the first locking member on each of the plurality of adaptor plates on the shaft.
A kit of wear protection elements for a longitudinally extending shaft supporting a helical screw flight, the kit of wear protection elements comprising:
- a plurality of adaptor plates being configured to be fixedly mounted to the shaft;
- and
- a plurality of wear segments, wherein the plurality of wear segments are configured to be mounted to the plurality of adaptor plates adjacent to each other as seen along the longitudinal extension of the shaft in an abutting relationship and/or in a partly overlapping relationship;
- and
- wherein the plurality of wear segments and the plurality of adaptor plates comprise complementary locking members.
A vertical grinding mill, the vertical grinding mill comprising:
- a longitudinally extending shaft supporting a helical screw flight,
- a plurality of adaptor plates configured to be fixedly mounted to the shaft, wherein each of the plurality of adaptor plates includes at least one first locking member, and
- a plurality of wear segments configured to be supported by the first locking members of the plurality of adaptor plates,
- wherein the plurality of wear segments are configured to be arranged adjacent to each other as seen along the longitudinally extending shaft in an abutting relationship and/or in a partly overlapping relationship.
