Problems solved by technology

[0007] None of the above addresses the problem of stop nut breakage during crushing operations
Furthermore, due to the size and weight of the components on the gyratory crusher, the replacement of the fixing mechanism with relatively large size components would be expensive and time consuming

Embodiment Construction

[0034] figure 1 is a cross-sectional view of a gyratory crusher 100 according to an embodiment of the present invention in which the moving cone 105 is removably mounted on the main shaft 101 via the head nut assembly 108 and the outer head nut 111 . The main shaft 101 has elongated bodies 102 , 104 and an intermediate portion 103 arranged between the elongated bodies 102 , 104 . The moving cone 105 is fixed on the main shaft 101 and is arranged to form part of the crushing chamber 106 of the gyratory crusher 100 into which the feed material is introduced to be impacted, compressed and twisted. Please refer to the enlarged view of 110, which shows the head nut assembly 108 and the outer head nut 111 with internal threads. The outer head nut 111 is screwed on the outer nut assembly 108 via the inner thread, and the moving cone 105 is fastened on the outer head nut 111 , so that the moving cone 105 is further fixed on the main shaft 101 . In one embodiment of the invention, th...

Abstract

A head nut assembly for securing a moving cone to a spindle of a gyratory crusher. The head nut assembly includes a cylindrical threaded member and a locking mechanism. The locking mechanism is arranged to engage with the threaded component. The crusher includes Figure 3.

Description

technical field [0001] The present invention relates to a gyratory crusher having a moving cone fixed on a main shaft to form a crushing chamber for crushing materials. Furthermore, in particular, the present invention relates to a head nut assembly for securing a moving cone to a main shaft via a threaded member that engages a locking mechanism of the head nut assembly. Background technique [0002] As we all know, a gyratory crusher is a mining machine that crushes coarse-grained minerals and stones. Gyratory crushers are widely used in industries such as metallurgy, building materials, chemical engineering, and water conservancy sectors due to their high dimensional reduction rate, high productivity, and uniformity of mineral particles. [0003] Gyratory crushers typically have a crusher shaft driven by a motor. The crusher bearing carries a moving cone, which partially forms a crushing cavity in which the material is impacted, compressed and twisted. The movable cone ...
