Embodiment Construction

[0052] Figure 8 A cross-section of a previously known gyratory crusher 100 is schematically shown.

[0053] The sole purpose of this illustration is to explain the basic operating principle of a gyratory or cone crusher and should not be construed as implying any limitation of the invention.

[0054] The gyratory crusher 100 has a vertically extending main shaft 102 and a frame 104 . The shaft 102 has a longitudinal axis coincident with the central axis A of the crusher. Unlike most gyratory crushers where the main shaft is suspended from star bearings, the one shown here is starless (bearing). The crusher comprises an eccentric assembly arranged in this previously known embodiment in the form of two eccentric rings 106 , 108 rotatably supported about a shaft 102 . The crushing head 110 is radially supported by the eccentric rings 106 , 108 and is rotatable about the eccentric rings 106 , 108 .

[0055] The drive shaft 112 is connected to the drive motor, and is provided ...

Abstract

A key liner segment (3k) for a top shell (1) of a gyratory crusher or cone crusher. The top shell (1) comprises a frame (4) and a plurality of replaceable liner segments (3) arranged in at least one layer or at least one row along an inner circumference of the frame (4), a side surface of each liner segment (3) facing an adjacent liner segment (3) in the layer or the row. Side surfaces (SK) of the key pad segments (3k) converge in a radially outward direction of the top shell (1). The present disclosure also provides a set of pad segments comprising a key pad segment and at least one complementary pad segment, a top shell for a gyratory crusher or cone crusher, a gyratory crusher or cone crusher, a method of mounting a replaceable liner segment to an inner wall of a frame of a top shell of a gyratory crusher or cone crusher, and a method of removing a replaceable liner segment from an inner wall of a frame of a top shell of a gyratory crusher or cone crusher.

Description

technical field [0001] The present invention relates to replaceable liner segments for use in the top casing of a gyratory or cone crusher. [0002] Gyratory crushers and cone crushers are two types of rock crushing systems that break rock, stone or other material, usually in the crushing gap between a stationary element and a movable element. [0003] Gyratory crushers or cone crushers include a head assembly comprising a crushing head that revolves about a vertical axis within a fixed bowl attached to the main frame of the rock crusher. The crushing head is assembled around an eccentric which rotates about an axis to impart a rotary motion to the crushing head which causes the rock, stone or Other materials are broken. The crushed material leaves the crusher through the bottom of the crushing gap. [0004] The eccentric may be driven by various power drives such as attached gears driven by a pinion and countershaft assembly, as well as several mechanical power sources suc...
