Cone crusher is suitable for crushing various kinds of ores and rocks of medium or
above medium hardness. Cone crushers have many features like stable structure,
high efficiency, easy adjustment, low operating cost and etc. The spring safety
system works as an overloading protection system which allows metals to pass
through the crushing chamber so as not to damage cone crusher. The safety
system adopts dry oil and water as two kinds of sealed formation to make plaster
powder and engine oil separated to ensure reliable performance. The crushing
chambers are depending upon the feeding size and the fineness of final products.
The standard type(PYB) is applied to medium crushing; the medium type is applied
to medium or fine crushing; and short head type is applied to fine crushing.
Working principle of Cone crusher:
Cone crusher crushes materials through the working surface between the
movable cone and fixed cone. The movable cone is supported by spherical bearing
and fixed on an hanging erect shaft which is set in the eccentric sleeve, which is
set on the stopping and pushing bearing. The movable cone and erect shaft are
drived by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven
by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is
drived by motor through v-belts.The lower part of vertical shaft is installed in the
eccentric sleeve.
