Grinding Mill Liners
For an operator the biggest effect that the liners will have on his job will be the result of wear.As the liners wear out the lifting portion of the liner will be reduced until the liner has a lower profile. This means that the cascade of the media will become flatter as the as the leading edge of the lifter wears away.
