Description

Technical Field

[0001] The utility model relates to the technical field of plate hammers, in particular to a high-wear-resistant ceramic composite plate hammer. Background Art

[0002] The impact crusher is one of the most widely used crushing machine types. The plate hammer is an important component of the impact crusher. When the material enters the plate hammer action area, it is crushed by the high-speed impact of the plate hammer and thrown onto the impact plate installed above the rotor to be crushed again, and then bounces back from the impact liner to the plate hammer action area to be crushed again. The plate hammer is one of the components of the crusher when processing materials, among which the plate hammer made of high chromium cast iron is more commonly used.

[0003] Since the plate hammer needs to collide and rub with the material when working, the plate hammer is easy to wear. In order to prevent the plate hammer from wearing, the plate hammer is often subjected to special heat treatment or a titanium nitride coating is connected to the surface of the plate hammer body; this often makes the manufacturing process of the plate hammer complicated. Utility Model Content

[0007] After the upper plate hammer is worn during use, the first upper ceramic block comes into contact with the material first. At this time, the width of the first upper ceramic block is large, which can enhance the use of the upper plate hammer and improve wear resistance. When the wear continues, the second upper ceramic block and the third upper ceramic block are worn to achieve gradient utilization.

[0008] As a further solution of the utility model, the first upper ceramic block, the second upper ceramic block and the third upper ceramic block are symmetrically arranged with the front side of the upper plate hammer body as the center, and there are ten of them evenly arranged.

[0011] After the lower plate hammer body is worn during use, the first lower ceramic block comes into contact with the material first. At this time, the width of the first lower ceramic block is large, which can enhance the use of the lower plate hammer body and improve wear resistance. After continued wear, the second lower ceramic block and the third lower ceramic block are worn to achieve gradient utilization.
