CRUSHING NATURAL ROCKS
NOTICE
If natural rocks are fed and crushed together with debris of high water content (earth, sand, etc.), not only the grizzly feeder may
be clogged, but also the packings at the crusher outlet and fixed and swing jaw crusher plates may be worn out prematurely.
To avoid such troubles, use an excavator equipped with a skeleton bucket, when loading debris.
When crushing natural rocks, do not set the clearance at the crusher outlet in the range of 55 to 100 mm (2.2 to 3.9 in) for fear
of damages on the machine and premature wear of the fixed and swing jaw plates.
When crushing boulders collected in a riverbed, set the crusher speed control dial to the MIN position, thereby preventing them
from flying off or floating and eventually enhancing the work efficiency.
The mobile crusher can crush rocks hewn or dug out in quarries
and tunnel construction sites as well as boulders collected in a
riverbed.
The grain size of crushed debris can be adjusted in the range of
100 to 200 mm (3.9 to 7.9 in) by adjusting the clearance at the jaw
crusher outlet.
