The main working part of hammer crusher is rotor that equipped with hammer head. As we know, hammer head is the wearing part which directly influences the crushing efficiency of hammer crusher. It receives the striking force and the impacting force from the materials at the same time. As a result, the working surface of hammer head would be damaged to cause the surface shape changed.
When should change hammer head? How to judge? Luoyang Dahua will you give you the detail explanation.
At the beginning of using hammer head, its surface and edge are not worn. Hammer head mainly receives the impacting force, at the same time, it receives the striking force from the materials in positive force, this makes the hammer head become deforming and uneven. If the hammer head is worn, the thrust face of hammer surface is separate, the opposite force of hammer surface will apply impacting force to the hammer head, while the tangential force applies cutting force to the hammer head. This situation directly reduces the impacting force during crushing, lower the production efficiency and increase the crushing time. Therefore, when the acting force of hammer head shifts, and the hammer is worn, that means the hammer head is time to be changed.
