The main wear element of such crushers is the hammers and disks to which they are attached. To study the strength characteristics of these parts, a technique and algorithm for studying the stress-strain state of the hammer crusher disc employing the finite element method (FEM) using computer simulation software products were developed.
Factors influencing the choice of a crusher also include the required output size. If you need a fine powder, a hammer mill with a high speed rotor may be ideal. But if you need a coarser output, a lower rotor speed may be sufficient. The kind of material you'll be crushing, its size and form, and the acceptable output size will determine the ...

The crusher rotor is the key component of the hammer crusher and impact crusher. AGICO customizes crusher rotors with different dimensions, shapes, and colors, as long as you provide us with specific drawings. ... The rotor's tungsten-titanium alloy armor-like protection design greatly reduces the stress concentration on the hammer disc and ...
Chrome steel typically has a hardness of 60 to 64 HRC and a very low impact strength of 10 J/cm². To prevent the breakage of chrome steel blow bars, there may not be any unbreakable elements in the feed material. Chrome steel is the common material in casting HSI blow bars because it has a very good hardness.
