Description

Technical Field

[0001] The utility model belongs to the technical field of sand making machines, in particular to a hammer head of a sand making machine. Background Art

[0002] The hammer of the sand making machine is a very important wear-resistant and consumable part in the industrial sand making process, and is widely used in stone factories, mineral processing plants and other industrial departments. It uses the high-speed rotating hammer to crush materials in the form of impact, breaking large stones into small pieces of gravel, and then the wear-resistant sand making machine hammer and the impact plate are used to break the gravel into fine sand.

[0003] In the prior art, the hammer head design of ordinary box-type sand making machines does not specifically distinguish the thickness of the hammer head and the hammer handle, and all of them are manufactured using a cold composite process.

[0004] After long-term use and observation, it was found that this hammer head could not protect the disc during work and had poor performance. If it was used too much or large materials were fed in, it would not be able to withstand the impact and would explode, resulting in it not being able to be fully used and having to be thrown away.

[0005] To this end, the utility model provides a hammer head for a sand making machine. Utility Model Content
