The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The specific embodiment is as follows:
Referring to Fig. 1 to Fig. 4, the ball mill barrel liner plate back side and ball mill barrel inwall contact-making surface are corresponding cambered surface, it is circular-arc groove 1 that every liner plate working face is provided with several cross sections, and the joint face of adjacent groove 1 is a cambered surface, and joint face is the bossing between the adjacent grooves; The two ends of shell liner are respectively equipped with a boss 2,3,3 and are dribbling end boss, and 2 is non-dribbling end boss, increases the plot ratio of liner plate, improves the ball ability of taking of liner plate.Dribbling end refers to ball mill in operation process, abrading-ball along rotation direction when every shell liner working face moves, the zone of the liner plate that contacts behind the abrading-ball; The corresponding other end then is non-dribbling end.
Preferably, boss is formed S shape structure by a concave curved surface and a convex surface, and the turning of boss is an arc, has cushioning effect, reduces the impact of abrading-ball to liner plate, improves the wear resistence of liner plate.
