Impact Crusher Material Hardness

1 hardness of the material. jaw crusher can crush most of material which compressive strength between 300350mpa. impact crusher is suitable for crushing medium hardness and less tough, brittle materials, such as limestone. if the material is hard, it will cause great damage to the wearing parts and shorten the service life.

There are many factors affect impact crusher ability. the hardness of materials. the more hard material ,the more difficult crushing up , but also for the equipment wear the more serious. the broken rate is slow, of course, crushing capacity is small.

Impact crusher material hardness. however due to the crushing board that is easy to wear it is also limited in the hard material crushing the impact crusher is commonly used for the crushing of limestone coal calcium carbide quartz dolomite iron pyrites gypsum and chemical raw materials of medium hardness

Therefore, large jaw crusher tooth plate is usually used zgmn13cr2 modified high manganese steel. for the jaw plate material should be selected high hardness materials to resist extrusion, microchisel failure, and also have sufficient toughness to resist the chipping impact fatigue failure.

Both impact crusher and cone crusher can act as secondary crushing machine, but the hardness of the broken materials is not the same. generally, the cone crusher mainly breaks some materials with higher hardness, such as granite, basalt, tuff, river pebble, etc., and the impact crusher is used to crush materials with less hardness, such as ...

Material hardness is one of the factors that affect the choice of jaw crusher. each stone or other raw material has different degrees of hardness and softness. before choosing a crusher, the user must know the hardness of the material. if the hardness is difficult to determine, it is recommended to use professional instruments to determine the ...
