Operation method for vertical shaft type impact crusher.

摘要

A combination of anvils (32) with deadstock spaces (34) enables the an extension in the lifetimes of the tips mounted on a rotor. A combination of hard tips (72L1) with soft tips (72L2) overcomes the inconsistency where the hard tips (72L1) are easy to be chipping-worn but ordinarily hard to be worn by collision with stones of a large grain size accelerated by the rotor, while the soft tips (72L2) are hard to be chipping-worn but ordinarily easy to be worn by collision with stones of a small grain size accelerated by the rotor. Crushers have anvils (32) and dead stock spaces (34). Crushers still have a pair of hard tips and soft tips mounted on a reversibly rotatable rotor. The pair of hard tips and soft tips are located in symmetry with respect to one of the center lines (L,M,N) in the angular orientations with respectively equal angular intervals, the center lines extending from the axis line of the rotor in the radial direction. <IMAGE>
