Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crusher hammer replacement structure. Background Art

[0002] Crusher, also known as rock crusher. It is a crushing machine used in the processing of metal and non-metallic ores to crush the mined raw ore into small particles by squeezing and bending. Hammer crusher has the advantages of large crushing ratio, uniform discharge particle size, less over-crushed material, and low energy consumption. However, due to the rapid wear of the hammer head, its application in crushing hard materials is limited; in addition, due to the fear of clogging of the grate bars, it is not suitable for crushing materials with high humidity and clay. This type of crusher is usually used to crush brittle materials with medium hardness or below, such as limestone, shale, coal, gypsum, and chalk. The ring-type coal crusher, which replaces the hammer head of the hammer crusher with a steel ring, is a variant of the hammer crusher. It uses the combined effect of high-speed impact and low-speed rolling to crush materials, so that finer products can be obtained. It is mainly used to crush coal for power plants, but can also be used to crush gypsum, salt chemical raw materials and some medium-hard materials.

[0003] At present, when crushers on the market are in use, especially hammer crushers, the hammer head is one of the core components of the hammer crusher and is arranged on the hammer shaft of the crusher rotor. The hammer head directly strikes the material when the crusher is running at high speed, and finally breaks the material into suitable particle size. In actual use, when the hammer head is arranged on the hammer shaft of the crusher rotor, most of them will use the threaded structure to limit the position of multiple hammer heads through the hammer shaft at one time. Since the hammer head needs to contact with the material frequently, the hammer head is prone to damage. When a single damaged hammer head needs to be replaced, the hammer shaft needs to be rotated and disassembled, which causes multiple hammer heads to need to be disassembled at the same time, making the subsequent installation of the hammer heads more time-consuming.
