When parking, check the gap between hammer head and screen bar, between
screen bar and screen bar, adjust it when necessary, and replace screen
bar regularly, so that it can be in an appropriate and reasonable range,
which not only meets the production requirements but also can not cause
accumulation. The internal clearance of crusher mainly refers to the
clearance between rotor body and counterattack plate, grate bar and
hammer head. The size of these clearances is related to whether there is
accumulation near the castor bars and safety doors. If the accumulated
material exists and the hammer can not press the accumulated material
down from the castor bar, the hammer will suffer serious wear and tear.
Therefore, in the process of use, it is necessary to regularly adjust
the clearance of each part so as to keep it within an appropriate range.
Controlling the water content of mineral materials, especially in rainy
season production, try not to shovel the mineral materials with lower
topography and more water content into the crusher chamber. It is better
to dry the mineral materials before they enter the crusher if
conditions permit, so as to reduce the water content in the mineral
materials, which is helpful to improve the hardness coefficient and
increase the crusher. The stress on the hammer head during work forms a
work hardening layer, but this method is limited by the requirements of
crushing materials and site.
