China has good old saying: steel to use on the blade. Similarly, crusher hammers nature also want to use the good metal! Crusher industry knows, unusually harsh counterattack crusher operating conditions, so the reaction type broken hammer head will need to use good material. The diamond is very hard material, but hard is not necessarily appropriate, Shanghai four heavy industry experts tell us counterattack crusher plate hammer will mainly adopt three kinds of material: high manganese steel, alloy steel materials, high chromium cast iron.
As a counterattack crusher hammer head, not only requires high hardness, its flexibility is more demanding! Because counterattack crusher plate hammer working conditions, especially in the high hardness and strength are broken material, for the plate hammer the tenacity of material requirement is very high. So counterattack crusher plate hammer will mainly use the three kinds of material: high manganese steel, alloy steel materials, high chromium cast iron. These three materials not only hard but also flexibility is better than other materials.
These three materials of high manganese steel has a history of 100 years of development, good toughness, work hardening under strong shock happen; Alloy steel materials with high toughness, low cost and good wear resistance, but in practice, due to low reserves, cannot meet the requirements; Life is long but the toughness of high chromium cast iron is not enough, easy to fracture.
Each part of machine for machine like people of every organ, they are all form an integral part of the whole! Like the famous bucket principle, short board decided how much water bucket can hold, the stand or fall of counterattack crusher hammer also directly determines the lifespan of the crusher! So Liming heavy industry experts warn the user, when buying a counterattack crusher must carefully distinguish between the material of crusher hammers.
