To judge whether the wearing parts such as hammer head and screen inside the crusher need to be replaced, we can start from the following aspects:
First, observe the crushing effect.
If the particle size of the broken materials is obviously larger and unevenly distributed, and there are more materials that are not fully broken, it may be that the impact effect is reduced due to the serious wear of the hammer head; It is also possible that the screen is damaged or the mesh is blocked, resulting in poor discharging effect.
Secondly, pay attention to the running status of the equipment.
If the equipment vibrates abnormally, it may be that the uneven wear of the hammer head causes the rotor to be unbalanced; If the screen is worn or blocked, the material will stay in the crushing cavity for a long time, which will lead to the increase of equipment running current and load.
Finally, pay attention to the change of output.
Combined with the actual production situation, when the hammer has been used for a certain period of time or the broken materials have reached a certain amount, even if the appearance and performance have not changed significantly, it should be considered to be inspected or replaced. Usually, for models with an annual output of two to three tons, a pair of hammers can handle about 4,000 tons of secondary materials and about 3,500 to 3,600 tons of primary materials.
The above is the relevant content sharing about the wearing parts of the equipment, so be sure to pay more attention in the production process.
