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.
Claims16
A system for a vertical grinding mill, the system comprising
- a longitudinally extending shaft supporting a helical screw flight,
- at least one adaptor plate configured to be fixedly mounted to the shaft, each adaptor plate comprising at least one first locking member, and
- at least one wear segment configured to be supported by the at least one first locking member.
A replacement kit of wear segments for a longitudinally extending shaft supporting a helical screw flight and at least two adaptor plates, the replacement kit comprising at least two wear segments configured to be directly or indirectly supported by on the shaft by the at least two adaptor plates, wherein the at least two wear segments are configured to be arranged one after the 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 at least two wear segments comprises
- a locking member having a geometry complementary to a locking member on one of the at least two adaptor plates on the shaft.
(canceled)
A kit of wear protection elements for a longitudinally extending shaft supporting a helical screw flight, the kit of wear protection elements comprising:
- at least two adaptor plates being configured to be fixedly mounted to the shaft;
- and
- at least two wear segments configured to be mounted to the adaptor plates one after the other as seen along the longitudinal extension of the shaft in an abutting relationship and/or in a partly overlapping relationship;
- and
- wherein the at least two wear segments and the at least two adaptor plates comprise complementary locking members.
A vertical grinding mill, the vertical grinding mill comprising a longitudinally extending shaft supporting a helical screw flight,
- at least one adaptor plate configured to be fixedly mounted to the shaft, each adaptor plate comprising at least one first locking member, and
- at least one wear segment configured to be supported by the at least one first locking member.
