Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the improved liner plate structure of the ball mill comprises a liner plate body 1, wherein a convex curved surface 2 is arranged on one side of the liner plate body 1, a plurality of cavities 3 distributed at intervals are arranged on the convex curved surface 2 on the liner plate body 1, one side of each cavity 3 penetrates through the liner plate body 1, and the other side of each cavity 3 does not penetrate through the liner plate body 1 and is positioned in the liner plate body 1.
Inlay in die cavity 3 and have bearing steel rod 4, specifically, die cavity 3 runs through one side of welt body 1 and is equipped with one side of convex curved surface 2 on the welt body 1, and it has both guaranteed that bearing steel rod 4 is inlayed in the inserting of welt body 1 effective length, increases the rinding body impact force again to increase grinding efficiency.
The bearing steel bar 4 is used as an insert casting object to be embedded in the ball mill lining plate cavity 3, the bearing steel bar 4 and the ball mill lining plate body 1 are compounded together after casting, the bearing steel bar plays a role of hard particles in the using process, and the structure of the ball mill lining plate body 1 is changed through the method.
The hardness of the bearing steel rod and the ball mill lining plate body 1 can reach HRC60 after water toughening treatment, the service life of the ball mill lining plate body 1 is greatly prolonged after the structure is improved, the ball mill lining plate body shows excellent wear resistance in the using process, and the ball mill lining plate has high market popularization value.
This improved generation ball mill welt structure's a plurality of die cavity 3 interval staggered distribution improves the homogeneity that the hard spot distributes, improves the life of welt body 1. Also, in particular implementations, the bearing steel bar 4 may include GCr15, GCr15SiMn, GCr4, GCr15SiMo, and/or GCr18Mo high carbon chromium bearing steel.
