Introduce the results of using different materials of the impact crusher plate hammer. Results of different hammers Hammer material Material hardness Broken material Relative wear resistance ZGMn13 180-200HB 1.0 Medium manganese steel 220-250HB limestone 2.1 [22] Calcined kaolinite 1.12 High chromium cast iron > 58HRC Manganese ore 5.0 [39] Quartzite 3.79 [40] Steel slag 2.42 [40] High chromium cast iron combined with carbon steel > 58HRC Cement clinker 4.1-6.0 [33] Cement raw meal 4.0 Low alloy steel 45-55HRC coal 5.0 [14] Medium carbon low alloy steel 50-55HRC 1.5 [18] Japanese alloy steel limestone 1.5 [39] Low boron cast iron Limestone + gravel 2.79-4.68 [40]
In summary, the wearable parts such as the jaw plate, the hammer head and the hammer are subjected to impact wear and cutting wear to varying degrees, and the requirements for high hardness and high toughness are required for the materials used, but the toughness and hardness of the material are A pair of contradictions, so in the actual selection of materials, we must fully understand the conditions of working conditions, and rational use of materials.
