The main reasons of why liners will be worn
Impact crushers are the the common equipment in mining industry.
Liners are the wearing parts of the impact crusher equipment. This
article will introduce the main reasons of why liners will be worn.
The liners suffer from great forces: While the impact crusher is
working, the fixed liner, the swing liner and the crushing material
are forcing each other. The surface of the liners are suffering
from complicated stress. The drilling, cutting and impact extrusion
are the main way of wearing.
1.The operating conditions are harsh: Because of the job nature of the impact crusher, the liners will
be worn unavoidably. If the impact crusher is under harsh operating
conditions, it will exacerbate the wear of the liners.
2.Hardness and grain size of ore is different: According to the difference of the hardness of crushing material,
the damage degrees of the liner will be different. The harder of
the crushing material, the much force liners will suffer. When
hardness is the same, the bigger of the feeding grain size, the
more serious liner will be worn.
3.The way of feeding material is improper: If the feeding machine of the impact crusher equipment hasn’t installed properly or the feeding material is too much, crushing
chamber will be blocked by the material or any other problems. This
will make the liners suffer from great forces, and strengthen the
wearing of the liners and the liners will be worn seriously.
